325iC problem help needed

Hey guys

Another project on my hand .

I bought this BMW 325iC 1995 with auto tranny , car sat since 2009 , last year out side .(owner stated car run great before the hibernation )

Car In very good shape with 111k.

Before starting it I did put battery , oil / coolant /plugs beside putting little oil in each cylinder before attempting to fire it .

Also I took the fuel pump out bench tested it , then drained the gas tank , new gas filter .

Time to start the car .

I turned the key nothing happen , all lights on the cluster but engine didn't spin NO crank.

Checked all fuses one by one all look good , so I figured it might be an ews issue , went to the dealer made another key ($96) as seller mentioned car might not have the right key .

Same problem nothing happen with new key ,no change .



Then I said I have to do the ews delete thing by crossing the wires behind the glove box .


Now car crank but won't start .
I tested the CPS it is putting out 520 OHM.

I checked for spark by taking the air intake box and spraying starting fluid while cranking , Nothing , it seem car not getting no spark /fuel.

I also tested the fuel pump plug no power there even though I bridge terminal 30 and 87 on pump relay.

with the bridging on pump relay I tested fuse 18 for power , dead no power there , I also tested continuity between pin 87 on fuel pump relay and both sides of fuse 18 NO continuity .

Known I got the same exact car , so I took all the relays from my running car and put them on this one like Fuel pump relay , main relay .

I also tested on the car a good working DEM 413 maroon after doing the wire snip process , no change .


I also tried starting the car in NUTRAL , same thing .

What I am missing ?

Why I am not getting NO spark and NO power to fuse number 18 ?

Thanks guys .

Long shot, but did you test the crank position sensor? A bad one (especially after it sat for so long) would explain the no spark.

Why I am not getting NO spark and NO power to fuse number 18 ?



Thanks guys .

First check that you have spark at the spark plugs.
I don't remember if EWSII disables both crank and ignition or just ignition (spark)


I feel you have something else going on over here.
First check that the spark plugs are producing spark, if no spark check causes.

Then check for fuel delivery, you mention there is no power at the fuel pump plug, two reasons that could be are
1- DME is not turning on the fuel pump, but you already checked the Crank Position Sensor (CPS).
2- bad wiring (been there), check continuity between fuel pump plug and relay.

To really cross out CPS put a test light (not a multimeter) at the fuel pump plug. Key off light off, key on light should momentarily turn on, crank and light will turn on. If no light at all and wiring is good then check with another CPS or that CPS is plugged in to correct plug, happened to me once. Also some people confuse the Crank position sensor with the Camshaft position sensor.

A bad Crank sensor = no start
A bad Camshaft sensor but good crank sensor = running car but poorly.


Also have you tested the MAF?


Since it did not start with starting fluid I'm guessing you have no spark. But could also not be getting fuel.

No spark , I even took the coil out shorted it to engine so the spark plug ,nothing .[/COLOR]


Crank position tested good , continuity between fuse 18and pump plug good I tested that . no power to fuse 18 though .




Have to check the light test today , I am sure plug in right spot .




Also have you tested the MAF?
no I didn't



Thank you

If have no spark then MAF does not play a role here yet but good idea to rule it out.

So I looked it over and EWSII disables both crank and ignition.

Here is some reading.

Check for all the items under "a" where is says engine no start.

This is a long shot but since you'll most likely be checking wiring check for your engine block to chassis ground. It is on the passenger side by the engine mount, might be missing, broken or corroded. Two things BMWs do not like bad grounds and overheating.


I do not have much experience with EWSII but if the coding is right and the key are right there should be no need to bypass it. Since its cranking now I think it means EWSII is not the issue, but there is something that's preventing spark.

bliger7gz thanks for ur help
Ground wire one of the things I checked , actually I took out and cleaned contacts .
I tested today coil and injectors , got power to both , but still no spark no power to fuel pump ,no power to fuse 18 even with the jumper on 30and 87 of FP relay .
May be I should try another CPS even though one on it testing good with 520 ohm .
PS: only cranks with the ews bypass , if I put every thing to original no cranking just lights on cluster comes on .

Found the problem , u wouldn't believe what people can do .
It seem the previous owner got some kinda fuel issue and messed with relay sockets , he moved the main relay socket to fuel pump spot and vice versa ,so the FP socket had the main relay and the Main relay socket had the FP relay lol it took me 10 hours testing today until I corrected the problem , car fired right up on carb cleaner , not taking gas even though pump running , so I got it going after all this time for like 6 sec few times , amazing how quite this engine is .
Now back to the fuel issue , I placed a fuel test gauge off the line coming to injectors rail , it seem pump not giving good pressure as I see the needle at 50psi when I jump 30and 87 on FP but when I crank the car needle bounce back and forth between 35 and 45 , got dark so tomorrow another day .
It feels good after this effort for days

So what I did today is what out lined in this youtube .


all diagnose looks good , pump getting power putting good pressure , system holding good pressure as described in this video , car still won't fire up unless I fog it with gas thru the air intake ( paint gun filled with gas ) with the fogging I can keep it running as long as I want , car runs nice and smooth , once I stop fogging it dies even though FP pump working.
It has code 1215 probable due to me moving the MAF out of the way ( still hooked though)so I can fog it , by the way I put another MAF from my running car ,no deference.
what I am missing here ?

The injectors aren't firing. Test the electrical pulses with a noid light. You can make one out of a #194 bulb. Straighten the wire contacts on the bulb, pull one injector electrical plug and put the #194 bulb in the plug, then try starting the engine while watching for a faint pulsing glow of the bulb. If the bulb lights, the injectors are clogged or dead. If the bulb doesn't pulse, the injector harness is faulty or the ECU is bad.

Did exactly what u recommended , got this 194 bulb from radio shake , pulse there , so I pulled the injectors out and bench tested them , oh boy oh boy that hibernation since 2009 seized those injectors so bad , they don't even click , for the heck of it I was able to free one up by soaking it with parts cleaner and wacked it with a screw driver , but I just ordered them of eBay remanufactured with 3 years warranty.
Thanks for the help

You're welcome! Glad it wasn't harness or ECU.

The car starts fine. But will not go over 3k and when it does it sounds like studder but doesnt have the jumpy hesitation. I changed fuel filter.. would a318i pump work for 325i i been doing research they said yes of its the tu version?
