Even though this relates to an E36, I'm posting it here because it has the same M50 engine and electrical system as the E34.

This is the story of a BMW lover's journey through diagnosing and fixing a no-start situation. First of all, I want to express a sincere thanks to a fellow forum member, Roberto Baggio (aka RobertoBaggio20). I would have neither had the courage to do this nor would I have had the information necessary had it not been for Roberto. He found a link to a fellow that had information about bypassing the security system on the car. If I did not have this, I would not have been successful. So again, thanks Roberto.

My E36 would not start about 6 months or so ago. I was in no hurry to fix it as this is a spare car. I probably would have been done a lot sooner, but I had to have knee surgery in early December and that really slowed me down.

Now, on to the story. I have a 1995 325is with 236K miles. This has been a very good car and has only had about 4 no-start situations. The first was a failed fuel pump. This was before I joined the forum or knew anything about working on BMW's. I had it towed to a mechanic. He diagnosed it and replaced the fuel pump for around $400. I had an old 85 Mercedes 300D that I was not a bit afraid to work on. I would adjust valves and service the transmission etc., but I was always intimidated about working on the BMW's because (I'm almost embarrassed to say this) I could not even find the darn spark plugs! I know, it was silly, but all I would do at first is change the oil. Anyway, I found Bimmerfest and as the saying goes, the rest is history.

The second no-start situation was a bad fuel pump relay. By this time I had found out about the Bentley manual and was well on my way to becoming a much more savvy DIY'er. I removed the air filter and squirted a little starting fluid into the intake. It started for a couple of seconds, but would not respond to the throttle. I made a fused jumper with an on/off toggle switch per Bentley instructions and jumped the fuel pump relay socket and the car started and would run just fine. I replaced the fuel pump relay and all was well.

The third no-start situation was about 1 ½ years ago. At that time, I had followed my usual daily routine and turned the key to crank it, but I "stuffed it", meaning I didn't let it fully catch before I let go of the key. After that, it would not crank. The first thing I checked was the fuel pump relay, but that was not the problem. I went through the usual routine of checking things, but it just wouldn't crank. I had no fault codes stored in the ECM. I messed with it for about an hour but it still would not crank. On the last try, it coughed a little and finally cranked. The frustrating part was, I never did figure out what caused it to not crank.

I continued to drive the car for another year with no problems. Then one day (a couple of days after a rather heavy snow fall), the wife got in the car and it wouldn't crank. It would turn over, but it would not catch and run. So, I started the usual process of diagnosing it thinking that it would be an easy fix. I was so, so wrong. First, I checked to see if the fuel pump was working. I pulled the seat and confirmed that I had voltage at the connector. I plugged it back in and proceeded to remove the fuel pump relay and use my jumper that I had made per Bentley specs. Sure enough, the fuel pump purred like a kitten. So, while the fuel pump relay was jumped, I tried to crank the car. It still would not start. Now I was thinking that I may have an electrical problem. However, to try to rule out a fuel delivery problem, I got out my trusty can of starting fluid. Yes, I know, one should not use much when attempting to start the car. It still would not crank with the starting fluid. Now I realized that I had a no-spark situation. I had never dealt with this on a modern car. I started doing research on the forum and Google. Next, again wanting to do the easiest thing, I put in a new DME relay and a new fuel pump relay. Still it would not crank. I checked the relay sockets (once I learned how to pull them up to get to the bottom of them) and they all seemed fine and had no corrosion.

I remembered a problem about E36's having a "wet DME" problem. So, I opened up the DME compartment, but it was dry as a bone. Next I suspected a failed crankshaft position sensor (CPS). I checked the resistance and it was about 500 ohms. Well, Bentley states on page 120-6 that it should be at 1280 + or - 10% (BTW, I found out later that it was a misprint in Bentley. It should have said 540 + or - 10%). So, I was way off or so I thought. I thought, okay, that must be it. I found a used one at a junk yard and bought it. When I got it home, it too was at about 500 ohms. I thought, great, now I have two bad CPS's. But it just seemed to defy the odds that two CPS sensors would be bad. So, I tested the one on my E34. What do you know? It too was about 500 ohms. I thought, well, if I put the used one on it and it doesn't crank, then I still can't say for sure that the CPS is not the problem because I can't be sure if the used one is good or not. So, I took the CPS off of my E34 (because I knew it was good since that car was running) and put it on the E36. It still would not crank. I put the original CPS back on and returned the borrowed CPS back on the E34 and it promptly fired up (remember this part for how it plays out later in the story).

Now I was becoming really frustrated and felt that I was reaching the limit of my knowledge and ability regarding diagnosing the problem. Just for kicks and giggles, I replaced the plugs. After all, they had (ahemm, clears throat) at minimum, 138K miles on them, but obviously they would not all fail at once. I decided to check the coils. They were getting proper voltage and had resistance within specs per the Bentley. But, I had no spark with trying to crank the car.

At this point, I basically narrowed the problem down to the DME. That's usually not a big deal right? I mean, after all, you just go to a junk yard and get one or buy one on Craig's List. So, I started my research. Well, I was not too happy on what I was finding. You see, the 1995 325 is a unique car in that it is the first year that BMW put the EWS II security system on the car. This is a system whereby there is a very small chip in the ignition key. There is a EWS antenna ring around the ignition tumbler. The DME is paired with the key and the EWS module. When the proper key is inserted, the antenna receives the signal from the key chip, it is sent to a unit that amplifies the signal. That signal is read by the EWS module which communicates with the DME and gives the go ahead to allow the car to crank. If the incorrect key is used, then, when the key is turned, all of the gauges and such will come on, but the engine will not turn over. This was confirmed when a while back, I had the very early stages of the dreaded "key spin". I tackled it as soon as I had the first signs of it so it was not bad to do. Anyway, I replaced my ignition tumbler and forgot to install the antenna ring. I tried to start the car and nothing. I just about left a big brown spot in my underwear until I realized that I forgot to re-install the antenna ring. Once I did, the car cranked fine. Whew!

Now, back to the story. The DME that is in my car is what is called a "silver label" DME. It is specifically for the EWS II car. So in researching, I found out that my options were pretty limited and the cost of repair was going to be quite a bit. A re-manufactured silver label DME was going to be almost $1200 from the dealer and on top of that, I would have to have the car towed to the dealer to have the new DME "re-coded" or "re-synched" to my specific car. Needless to say, I did not want to chunk down this kind of money on a 15 year old car with 236K miles. So I also looked into having mine re-built. I came across these guys at bmwdme.com. They will test the DME for $50. If there is no problem with it, they send it back to you after you pay the $50. If it is bad (assuming it is not massive damage from a fire, drowning or severe electrical shorting), they will repair it for $475. This was certainly better than the approximate $1300-$1400 it would cost with a remanufactured one (taking in to account the tow and labor at the BMW dealership for re-synching it).

Here is where Roberto really came in to the picture. He was kind enough to research this problem for me (without me asking him to do so BTW). He came across this fellow's blog. His name is Richard. Here is the link: http://qcwo.com/technicaldomain/ews-deletion-chip. He communicated back with Roberto and advised that a standard "red label" 413 DME (for the 1992-1994 M50) would work if the EWS system is bypassed. Roberto forwarded the information to me. I started my search for a red label DME. I am located right between two gold mines in the form of Pull-A-Part junkyards. There prices are unbelievable. A DME would cost about $30. Only problem is, people know this and the on of the very first things that gets snagged is the DME. So I constantly searched for a red label DME. One day they put a VANOS M50 E34 on the lot. I got there the very same day, but the DME was gone. I also searched Craig's List. I finally found one from a 93 325i and got it for $60.

I had to remove the glove box to access the EWS module. Bentley leaves out one important information about a bolt that holds the glove box assembly in the car. It is a 10 mm bolt that is located above the glove box light. Pop the light out and you have easy access to it. Locating the EWS module was the next challenge as there are several modules in there. The instructions given were to cut wire #4 (green) and then cut and bridge wires #1 and #3. The wires are not labeled this way so it was a challenge to figure this out as well. With the assistance of the wiring diagram in the Bentley manual, I was able to determine which module it was (it was the module in the lowest bracket with a yellow connector) and locate which wire to cut (the green #4 wire is the very small, solid colored wire), and which wires to cut and bridge (#1 is black/yellow and #3 is green/black).

I consider myself an electrical moron, so I have to tell you, I was scared to start cutting and bridging wires. So, I cut the green wire #4 and capped off each end. I then cut wire #1 and #3 at the EWS module and spliced them together. I put the red label DME in the car. I turned the key and the dashboard lit up as usual, but the engine would not turn over. Remember me mentioning how the EWS was activated when I forgot to put the antenna ring back on the ignition tumbler when I replaced it? Well, I knew that the EWS was being activated because it was the exact same scenario. So, I also spliced wires #1 and #3 on the DME side as well. Again I tried to crank the car. This time the engine would turn over, but it still had no spark and would not crank. Now I was really ticked off and thinking that I had no chance of fixing this thing. So, I just put the wiring back to as it was from the factory and I put the silver label DME back in it with the intention of having it towed to my mechanic.

By chance, I thought I would get a used camshaft position sensor and replace it, but to my understanding, a bad camshaft position sensor will not cause a no-start situation, but can cause the car to run poorly. So, off I went to the Pull-A-Part and found an M50 that had had the intake removed, so it was a breeze to pull it. Due to weather and issues with my knee, I didn't work on the car for a couple of weeks. The other day it was nice out and my wife was doing some things and I commented to her that I had just decided to have it towed to my mechanic. My fear is that he would spend a couple of hours (at $80/hr.) just to diagnose it and he may well say it had a bad DME. So I would then have to send the DME off for a $475 repair. As I told her this, she said "what about that wire you bought?" I asked "what wire?" She said "you know, the one you bought at the junk yard the other weekend." I was like "oh yeah, the camshaft position sensor I pulled at the Pull-A-Part". So, I opened the hood and began trying to figure out how I was going to get the VANOS off so I could remove the sensor. As I looked around, I saw an electrical connector under the intake manifold that was not connected.

I traced it and found that it was the connector for the CPS. Remember earlier in the story when I took the CPS off of my E34 and put it on the E36 and it still would not crank? Earlier when I was swopping the CPS from my E34 to the E36 and it didn't work, I proceed to take the CPS back off and put it back on the E34. I bolted the original E36 CPS back on the front of the engine at the toothed wheel. Well guess what, I didn't re-connect the sensor (doh). I was like, "well crap, that explains why it wouldn't crank with the red label DME". Just for kicks and giggles, I re-connected it and tried to crank the car with everything stock (silver label and stock EWS wiring set up). But just as expected, it would not crank and seemed to have no spark. So, I proceeded to do the red label DME swap again. I put it back in and re-did the EWS delete wiring bypass.

I tried to crank it again. It would not crank, but sounded like it wanted to. So I tried a one second squirt of the starting fluid in the intake at the MAF. I tried again and still no start, but it sounded like it wanted to crank even more. So, what the heck, if one second is good, two seconds should be better right? So, I gave a good two second squirt and tried again.

It did not crank up immediately, but just like something winding up, IT FINALLY CAUGHT !!!!. It ran rough for a couple of seconds, then smoothed right out. I didn't let it run long because I had not yet filled and bled the coolant system. I shut it off and waited about 5 minutes. I tried it again and it cranked up immediately. So in the end, it was the DME that was bad and the red label DME swap into an EWS II equipped car does indeed work. After about 6 months, the lifters were noisy on start up. This was due to leak down of the lifters over time. Also, the VANOS was rather noisy. After bleeding the coolant system and making sure everything was okay, I took it out for a short ride (7-8 miles) without revving beyond 2500 PRM. By this time the lifters had pumped back up and the VANOS quieted down.

Here are some morals of the story that I learned:

If you have the desire, persistence, a good repair manual, some decent tools and some basic mechanical skills, you can do most anything on the BMW's (well, at least the older models like E36, E34 and earlier). Realize however that you may have limitations on your abilities. I'm not at the point that I would feel comfortable doing and R&R on a head gasket or head. Sometimes you just have to take it to a mechanic.

Don't be afraid to ask for help from other BMW owners who may have experienced the same problem. Listen to their input. This forum has some of the nicest and most knowledgeable people around.

Be willing to do research on the problem. Remember, Google is your friend. Search it and search this forum as a lot of the problems have been experienced before.

Don't just throw parts at a problem. Try to be methodical in your approach. Think things through thoroughly. If you get stumped or frustrated, take a step away from the vehicle (sounds like you're being arrested lol) and take a break. Take time to "re-charge" your batteries so to speak. Sometimes during that break a moment of clarity will come that will point you to the problem.

Always double check your work. Had I realized that I failed to re-connect the electrical connection side of the CPS, I would have had the car running a couple of weeks sooner.

I hope this long winded dissertation has or will help someone who faces a no-start situation.

Best regards,
Steve

I have my car running woo whoo the problem is that I don't have power to the pin 86 at the fuel pump relay, I jump it then sounds like wanna run but doesn't so I check the firing order and it was bad, so I fix that then the car runs :) now I have to figure it out why that wire has no power, the manual says that is power from the ignition switch but I don't see any red/black wire on the switch, also it has a vacuum line coming from the intake that is not hooked up to anything, I'm wondering where that goes
 
#66 ·
Congratulations :thumbup:

Have you checked/traced the red wire at the base of the fuel pump relay socket? As best as I can tell from reading the wiring diagram on page ELE-9 of the E36 Bentley manual, the power for the fuel pump relay should come from the B+ jump start junction point :dunno:

Anyway, props for continuing to search out the problem. Once you get everything straightened out, I would love a write up and synopsis of what the problem turned out to be.
 
#67 ·
There is b+, and ground coming from the dme, what I don't have is power to the red/black stripe wire, the manual says that wire has to have power with ignition in on position, at the same time I dont have low beams,hazards or ac cluster, so I'm thinking it could be related, but I don't know, I'm going to work on my car after work and I let you guys know
 
#68 ·
I see. Are you testing for voltage at that wire while someone is holding the key in position #3 (cranking position)?
 
#70 ·
Ok. I'm pretty poor with electronics, so forgive me if I make suggestions that make no sense.

I am fairly confident that the fuel pump is not energized until the key is turned to the #3 position (cranking position). I would suggest you test with the key in #3. If it cranks, then it sounds like you need a new fuel pump relay if I'm reading everything correctly.

Good luck and keep at it.
 
#71 ·
ok so i was studding the wire harness and it looks like the wire gets power from engine control module relay, so im going to trace that one today and see whats up, im excited to get that car on the road and see how runs, i have it all apart right now, and i have to have my lights working too and some other stuff, but definitely im getting close, thanks to you guys, ill keep you guys updated:thumbup:

Steve, I wanted to say that is a very resourceful information regarding taking a break, think it through and reattempt the problem, yet the most of important news of all - "process of elimination - is what I learned in School currently, as I completed a course in electrical, everything has a set value to work if it falls or exceeds the limit it won't perform, depending on it's system: as I start up my BMW collection soon, I honestly cannot decide between two cars, the 1989 535i needs a transmission rebuild, and a 1992 BMW needs electrical related rework in the ignition system: both cars are fairly straight in body, interior the 89' is better, like the classy look, however am partial to the elegant BMW body the 92' has... please help me choose thanks... with Regards, Justin B.
 
#74 ·
Hello Justin. Welcome to the Fest!

I'm slightly confused due to your statement of being partial to the body style of the 92. If the 89 and the 92 are both sedans, then they should have the same body style (E34). Anyway, I would personally prefer to tackle an electrical issue (assuming that the car wasn't flooded, in a fire etc.) than worry about a failed automatic transmission .... unless you are inclined to do a 5 speed swap (I think South26 has a 5 speed swap available for the 535). Ultimately, you will have to decide. Good luck on your choice.
 
#75 ·
Ok guys so finally I have my car on the road, ended up been a mess with relays, ( besides dme,ews and key) everything works now, and I take it for spin today, I wanna thank all you guys for your help in the process, tomorrow I'm going to fix an small power steering fluid leak and thats it, I hope this threat help other guys to fix problems, and I some one have problems with your car let me know, I'll be more than happy to help :)

I dont know how i missed tis thread in april. But it was a great read. It really has been a while since ive been here, last we spoke steve, you were still fighting that no start. Very happy you fixed it though,
Almost as happy as knowing that My car has a Red Label 413 :)

I'm dreading firing it. It's be 6 months not only not running, but not running without a valve cover. I'm an idiot.

I'm sure everything will be fine. So you have a red label 413? When did you do your swap? Keep in mind that the Vanos will likely be very noisy upon start up and for the first several miles. You may want to pull the fuel pump fuse or fuel pump relay and crank the car over a few times to allow a little oil pressure build up.

Let us know how it goes.
 
#79 ·
That's a good idea. I'll do that.
My car was produced in 9/94 as a 95 model year so the 413 Red label is OEM. Just got it at the absolute best time, new model year with the good previous DME.

Just thought I would ask.. I have a 97 528i e39 Do you know if/how I can bypass ewsII ? Having issues with no cranking when trying to start. Sounds like I may be having communication issues between dme and ews but my mechanic seems to think it is ews issue. I am willing to bypass ews if it will get my car on the road. Posted question/thread in separate post. Just thought I would ask you guys.

Thanks in advance

#82 ·
Hello Cory. I believe the E39 has the EWS II and I believe it can be bypassed. However, I'm not sure and haven't done it on an E39 so I don't know any specifics. Did you post this question on the E39 forum? They might be able to help.
 
#85 · (Edited)
Sorry to hear you are having trouble. No-start situations on these cars can be a real bear to figure out. Can you advise what symptoms you began to have that lead you to the conclusion that your EWS is not functioning properly? There are several things that can mimic a bad EWS. If you will, please give more detail. Have you checked the status of your battery? Have you ruled out a bad neutral safety switch? Prior to cutting the green wire, would the engine turn over when you went to key #3 position or did nothing at all happen?

If I am not mistaken, the green wire of the yellow connector is the #4 wire that needs to be cut. However, I also believe that #1 and #3 have to be cut and bridged on one side (don't know if it is on the DME side or the module side). On mine, I had to bridge the #1 and #3 wires on both sides, but, I also had to do a DME swap since my DME went bad. Mine was also on the E36 and after conversing with Supertech777, he advised that the wire colors on the module are not the same on the E34. I can't confirm that because the downloadable Bentley that I have is missing the pages for the wiring diagram for the EWS.

Supertech777 wound up buying a EWS delete chip and he was still able to use his silver label DME. Perhaps he will chime in today since he went through the same problem.

PS: Make sure to cut any wires with enough of a pigtail to re-connect them if necessary.

EDIT: I just realized you are having the problem with your M3 and not an E34. All of the wring cuts/modifications I did were at the yellow connector at the EWS module. The colors of wires listed in the original post should be correct for your car.

One night I locked my keys in my car while they were still in the ignition, so I had to break into the car and pop the lock to open up. Right after that the car wouldn't crank at all, ok so maybe it was the battery; unfortunately, had that load tested and the volts + CCA were still good.
Since my car is a 95 I do not have a neutral start switch (or maybe it was taken out because I haven't used the clutch since ownership).
Before cutting the green wire, the engine wouldn't turn over all, no fuel pump noise, no starter click, nothing. and even after cutting it, nothing. Just lights and instruments.

I didn't know about wire #1 and #3, so I would have to cut them than cap them together? both lines? and at both sides (DME and under glovebox)?

I also found a EWS ring and a separate key under my steering wheel today, they were taped together, but the key doesn't turn in my column, I'm so confused by this new find.

Okay. So you have a manual transmission so that rules out a neutral safety switch. I'm not sure how breaking in to the car would activate the EWS. Since you found the extra key taped into an EWS ring, it sounds like someone swapped out something in the ignition portion of the steering column, but kept the key and EWS ring to trick the EWS system into believing all was well. Did the EWS ring get disconnected? If so, try re-connecting it and re-connect the green wire. It may be that simple.

As far as wire 1 & 3, I had to cut and bridge them on both sides, but again, I was swapping my DME because it was bad, so I'm not exactly sure about just bypassing the EWS.
 
#88 ·
Nope EWS ring still connected, is it likely that the key column has been changed so the key I ordered from BMW this week is not going to work when it comes in? :mad:

My DME is not stock either, I forgot to mention I have a S50b30euro in the US spec M3... So wires 1 and 3, I cut both, leaving me with 4 wires in total, so I connect 1 & 3 and 1&3 and do that on the DME side as well? Is that what you did? If so I'll give it a try because I have no use for the EWS system and I can always splice back the wires together if nothing works.
 
#89 ·
Crap. The new key will likely not work :cry: Why did you order a new key?

Regarding wires 1 & 3, yes, you need to bridge them on both sides. As you said, you can always re-connect them if needed.
 
#91 ·
I don't think the key will be a total loss though. It should unlock your doors, but will likely not work in the ignition. Good luck.
 
#92 ·
Ok so I put together wire #1 and #3 and just cut #4, all under the glovebox.

Like this:

Image


You can see wire #1 from the engine and #3 from the yellow harness together, and I have the other set doing the same thing and than I have the #4 just sitting there cut.

I also have the RED DME with a ews delete as seen here:

Image


Image


Let me know if anything looks weird. Did you cut the wires connecting to your DME in the engine bay as well?

By the way, it didn't work, no starter no fuel pump, just the regular old lights and dash. Any more suggestions?
 
#94 ·
Okay. A couple of things. The red label DME you have is not a standard red label 413 that I swapped mine with. My guess is because your engine is not the M50. Having said that, I'm not sure the wiring trick I used will work.

Secondly, I don't think the problem would be your EWS if your DME is already bypassing the EWS.

I could not really tell how you joined the wires in your pictures (although they are very good close up shots). I'm a horrible artist, but I drew this diagram out to show the wiring modifications I did along with the red label 413 DME swap:

Image


All of the modifications seen in my drawing were done there at the EWS module connector.

If none of this works, then you may need to consider finding a used DME like you currently have.

However, although you don't have an automatic, I think there is still some type of switch that is engaged when the clutch is pushed in so the car can crank (i.e. similar to a neutral safety switch in an auto). If so, then that switch may have failed.

Don't know if this helped you much.

IT WORKED :D I switched my wiring to yours and everything powered up and car came alive!

I'll write up a DIY on bimmerforums for this and throw a link in this thread, probably tomorrow after I'm done ripping enjoying my car.

Once again, I couldn't have done this without you BMR_LVR so I would like to say thank you, I will also give you credit in my DIY.

THANK YOU!

Ok, I've been following this thread and I have a question. The differential was being replaced on my E36 and while waiting for the part, the mechanic left the key in the ignition. Now he can't test drive the car because it won't start. Does this sound like a EWS II issue to you? I only have one key. Should I get a new key programmed or go through your ring replacement process?
 
#99 ·
Hello Dez. "Because it won't start" is way too vague to determine if there is a problem with the EWS on your car. There are so many things that can cause a no-start. Firstly, what happens when it doesn't start? Does the engine crank over? If so, I doubt it is EWS. If all gauges and lights on the dash come on, but the engine will not turn over, then EWS is a possibility. There are other things that can cause the same symptoms, such as a failed neutral safety switch, failed starter or starter relay, etc. I would not think that leaving the key in the ignition would create a problem with the EWS. I would personally think that other systems need to be ruled out first.

Don't know if this helps or not.

I tried to sent this on the 17th but I didn't do it correcttly.........

Thank you for the quick response. I apologize for the lack of detail in the original post. I've spoken to the mechanic to verify the current status of the situation. It's not the battery. The ignition was removed. The starter was bypassed. All power is on but it won't turn over. The security light is blinking. We discussed the ring as well. He says he has the software to test the electrical and mechanical components, but cannot determine why it will not start. He has played with the power locks and ignition in different sequences. We are trying to avoid going to the dealer and spending more money. The supervisor at the dealership sounded like she had no clue. She wants me to tow it in so they can run diagnostics. I drove the car to the mechanic and it has been on a lift for 2 weeks with the key in the ignition. The work was done on the rear end. The differential was replaced and the ring that connected both ends of the drive shaft was replaced. 2 support arms were replaced to stabilize the front wheels. Nothing electrical was worked on. Any suggestions would be appreciated.


Thank you,


Desmond

...It's not the battery.
  1. The ignition was removed.
  2. The starter was bypassed.
  3. All power is on but it won't turn over.
  4. The security light is blinking...
  5. ... I drove the car to the mechanic and it has been on a lift for 2 weeks with the key in the ignition.
  6. Nothing electrical was worked on.

Can you give more info/details as how the battery was ruled out as not being the culprit.

I'm trying to wrap my mind around the fact that the ignition was left on for 2 weeks as the car remained on a lift...yet...now that the car won't start...it's not due to a severely discharged battery...which is what would happen to a battery left on for two weeks.

Again, its not that it couldn't be something else...but from what we've been told...I can't see how your battery could not be the issue without more details as to how the battery was ruled out not to be the culprit.

Did they give you any specs on the battery? Did they recharge the battery then test it again to see if it's still holding a charge? What are the battery's voltage numbers when they put a meter on it? How about when they put a load on the battery...does the voltage drop off like cement block thrown in the river...or does it retain enough cranking amps to start the car?

Left on for two weeks...a car battery could discharge to the point of permanent damage...especially if it's already had over a couple of years service.

^ I assumed that OP meant that the key was just left in the ignition (in "0" position) for the 2 weeks. I don't think that situation would cause his problem.

However, if your understanding of his situation and your scenario is correct, then I agree completely that the battery could be toast.
