545i crank but wont start, HELP ASAP

me and my buddy were trying to diagnose his secondary air pump code, so we followed a DIY on youtube about testing the salmon colored relay under the passenger side air filter in the relay box.
the DIY said to insert a wire in two spots where the relay would go, and then to turn the car on to see if the air pump turned on. he started the car and i saw what looked like a tiny spark come out, but it was not where i plugged the wire in. it looked like it was a few inches away. but i could be wrong.
i also cleaned the MAF sensor. we put everything back together and the car wouldnt start. we attempted many times. i need help ASAP because the car is blocking my driveway and we cannot push it aside because the power steering wont work unless the car is on. and i would like to fix this asap because he is out of a car and using mine for now.
i attached a video of me trying to start the car. i need some serious help here guys. what do you think went wrong? is there anything i can do to check what it could be? all of the fuses in the trunk and glove box are ok. you can hear the car is just cranking and trying to start but it wont. it just keeps doing this until i pull the key out.

please help!!

If you saw a spark when you were doing what you were doing, you likely fried something - hopefully nothing serious. I don't know where the fuel pump relay is located, but since you were mucking about with another relay, perhaps it's in the same general location and you fried it (sounds like it's not getting fuel). Anyway, check to see if it's throwing any codes and go from there. Are you getting any errors on the iDrive?

Additional info: Have a read here - http://www.honestjohn.co.uk/forum/po...ex.htm?t=70672

It pertains to a diesel E60, but the electronic bits should be relevant.

This is a stretch, but I only add it because of the "crank, no start" problem. The below happened to me. There is no SES light, but codes are thrown that can be detected by INPA.

Quote:
Folks, this was an odd one. Probably my fault, but it seems to happen to enough people for various reasons that it's worth a thread someone can find in the future. Also, people get sold a new CAS when all they need is a simple software reset.

Symptom is that everything works, engine cranks fine -- but no start (and no SES light). Fire up INPA and you'll see various codes, but the one that's the problem is '4A63 EWS Manipulation'. Means that two modules aren't synched, so the car believes there is a security problem and immobilizes the car.

The fix is easy (with INPA). E60>>Engine>>N52 [in my case]>>Shft F6 EWS -- Start value comparison and Shft F7 EWS CAS -- Start value comparison. In my case, EWS CAS resynched the modules and the car started right up.

NOTE: My INPA had "valve" instead of "value". Since screwing with the valves in INPA is not something you leap into, it took awhile to figure the bad translation. Must have looked that this five times wondering what valves has to do with the EWS....

NOTE: Different engines have this selection in different submenus, I'm told. I didn't confirm this.

and NOTE: This can be caused by multiple issues with keys, but also by newbies getting too random while learning INPA. Probably what happened to me. I learned a lot while I diagnosed it, testing fuel pump ops and so on. Also, tried several Web suggestions (insert key in door twist left and right; or use valet key), and neither fixed anything.

So, if you get a "crank, no start", check for this fast fix via INPA. Good luck.
If you know someone with INPA, hook it up and check this possibility. Pulling fuses may have screwed up communication between modules.

One more item: it's likely you depleted your battery while cranking. It can happen pretty fast with BMW's. Put a charger on it, or jump it to another car, while cranking.

Good luck.

When you put the key in ignition, do you hear fuel pump run for few seconds? (remove rear seat and listen for the fuel pump noise).
If you don't hear pump running, very likely, as someone suggested above, fuel pump relay/fuse may be toast.

thanks for your prompt replies! its highly appreciated. im stressed out so hard right now.
on another forum i asked the same question and someone said i might have fried the DME?
would this be likely? does it sound like what i have in the video?
i will check the relay today. hopefully its ok. how would i check it with a meter?

thanks guys!!

Okay, you need to answer pcy's question: Does the fuel pump run briefly when you put the key in the ignition? That should tell you if your fuel pump relay is working or not. Let us know what you find and we'll go from there.

pcy is right.

If you have INPA, you can test the fuelpump ops through the program.

If not, you might need to have someone put their ear next to the rear passenger side seat to hear it click. The fuel pump in located in the tank, under the seat. Good luck.

U can also disconnect the fuel line to the the fuel rail line. ( easy to disconnect ) get a small hose to a plastic water bottle and put it it on the fuel line.. Have someone turn the key and it should spray into the bottle. Then u will for sure know whether ur getting fuel to the fuel rail. Pull a coil pack and check spark to the plug. U need to make sure u have fuel and spark to the cylinders to help narrow it down and give u an idea what direction to go to find the issue . good luck and keep us posted

I had a similar problem, but i caused by something else. I have access to INPA and my issue was(actually still is) I was getting EWS fuel manipulation code, which I have to take care of through key-immobilizer sync in INPA. My pump wasn't engaging either on open door/key, but I could start it via INPA.

There are many you tube videos on relay testing. dme relay looks exactly the same as the fuel pump one under the glove box.

Check out this video on how to test them:

hey i want to first of all thank you guys all so much for your responses and help.
i tried to troubleshoot it but couldnt hear the fuel pump. i checked all the fuses. the diagram in the trunk said the fuel pump relay was the 20amp fuse in the trunk. it tested fine.
i finally had it towed to a bmw specialist shop because i felt bad and didnt want my friend waiting too long for the fix. they said they scanned it and there was "a ton of codes"
so im fearing the worst and thinking its an ECU fried. they said their master tech will be in on monday and be able to diagnose it for me.

if it really is the ECU/DME, do i have to buy a brand new one from the dealer and have it programmed? or can i buy a used one and have it programmed.
im reading that its VIN specific and the car wont work with a used one unless its reprogrammed. but then that coding the used ECU can cause problems.
this was old information so i dont know if someone has found a way around this yet.

im hoping for the best, hoping they find out its just a relay or something. all i can do is hope its not a $2,000 repair

I have read that you'll need a new DME if the old one is fried, not possible to use a used one

(for the low low price of $1200+!)

Schpenxel is correct that you cannot just install a used DME and expect it will work.
The VIN must match the car and the DME, EWS and key use rolling codes that must match.

There are places that will repair your DME. Or you can buy a reprogrammed unit they sell, or send in your own used DME to be reprogrammed with your VIN and the rolling code by using one of your keys and your EWS that you send in when you order (this is how the dealer programs a new one).

I have the same issue after my 550i was done some body work on. Have no spark and no fuel. I was thinking some type of immobilizer kicked in but dealer said that would shut down the starter also,key being lost its coding with car also dismissed by dealer...im about to take it to a diagnosis to the dealer and ill let u know what they will come up with,maybe it helps
