Electrical / Dead, no start. Timing chain feels tight

similar thread. However, I have no power to the fuel pump. Dead on both plugs to the pump. If the engine had no compression would it fail to close the circuit for the fuel pump to engage?

damn guys, I had a bmw guy I ran into come look at the car. motor is no go he said to have it rebuilt. What sucks is I had him come over after I saw another thread of a related problem with a youtube video attached. Basically the guy said the cranking is way to weak and he thinks the timing chain guide is probably broken.

 He hand cranked the motor and didnt like what he heard. Well, Ill double check the compression numbers but it looks like I might need a new motor. My father was driving the car when it died and he was only backing out of the drive way!?

good working icv? Also may be interested in ecu? Or do you just have the blocks.

Just checking in.

Good deal on fuel pump relay? Or is it the wrong product.

That Bav auto article is quite informative. Ill follow through the steps tomorrow and repeat the tests myself. My mechanic friend who is helping me is quite impatient and irrational maybe if I slow down and think Ill be able to locate the problem (it works for psychology). lol

Thanks still! The problem will be solved!

I'll take the second one. Two-prong is fuel pump power, three prong is the fuel sender for your gas gauge.

Ok. No power at the fuel power feed. Thats not good huh? I also did the jumper test with a wire in 30 and 87 with no power. Damn, not looking good. I will re-test. However, what am I looking at if no power to pump feed?

Guys, I think Im getting to worked up and not properly reading my materials. Im begining to think that its a relay issue.

Im going to grab some coffee and re-read.

My only big question is.

1.) How powerful should my fuel pump, pump when connected to a car battery?

2.) Which connector feeds power to the fuel pump? The two prong connected to the white socket? or the three prong plug connected to the black plug?

Im thinking the black plug may be the fuel level unit and I tested power on it instead of the pump power.

Ok, old cps tested bad. Thus, all is not a loss and it may have caused a problem else where.

I pulled the fuel pump. Tested it, it worked however, it was hooked up directly to a 12 volt battery and didnt seem to be running very fast. Im guessing that it is bad. However, my only question is why didnt it run slightly when I did the jump test (with a jumper wire in socket 30 and 87)?

Since it was bad, would it simply not have enough juice to run?

Also, I tested for power at the rear of the car and got power to the fuel pump feed with the jumper wire in place.

new cps. still not start. =(  e36 cps and crank sensor from e36 and it still just turns over.

Reset button any where for ecu or fuel pump?

It's part #3 in this diagram, around $22 at pelicanparts.com. You might find one cheaper in a salvage yard that has some M42 E30s in it.

i work in one lol. no e30s but a couple e36

The stomp test uses the throttle position sensor to signal the DME to display all codes.  Turn the key to position 2 (don't start the car) and pretty quickly press the gas pedal all the way down five times.  You should see the CEL start to blink.  It takes me a few tries, the timing has to be perfect.

When I had a no start like yours, the only code it displayed was 1215, bad MAF.  Needless to say, the MAF was OK...it was that damn CPS.  So definitely test that first.  You also don't want to have to replace it...I had to pull the A/C compressor & mount to pull & clean mine.  It was filthy from a leaking crank seal, and once you get enough rust stuck there it'll fail to signal the DME.  However, once it was clean the car fired right up.

Check the resistance on the crank position sensor.  Believe it or not, the fuel pump will not prime the system if the CPS sends no signal to the ECU/DME.  Resistance should be 640 ohms +- 10% IIRC.

Next likely candidate is the relays.  There are three that are not in the relay box, they're under that long thin plastic cover on the firewall.  They're the main relay, fuel pump relay and O2 heater relay.  Test those by pulling them & jumping their sockets in the car.

Last candidate is the fusible link.  Only do this if the check engine light is good but never turns on.  There is an 80amp link buried in the positive lead wire coming off the battery in the trunk.  You'll see a long plastic protective shroud on the passenger rear wheel well...remove the plastic nuts & move it out of the way.  The small wire powers the DME among a few other things.  It is not fused and passes through no relays.  There is a lot of heat shrink tubing...but you'll eventually find a small silicon board, and it should have a tin strip running along it.  My 325is didn't on day...that's how I found it.  I used a bolt to reconnect it...you could splice in a 40amp inline fuse holder I suppose.

stomp, produced a 1444. like i guessed. new cps ftw

If you're getting spark to every plug it's not the ECU and most likely not timing.  I would check fuel.

Yes, Im thinking CPS, or fuel. On that note if cps is gone it will not inform the ecu that the engine is spinning to close the circuit and prime the fuel via fuel relay and fuel pump.

CPS tested bad, so ill replace and if that doesnt fix the problem, ill pull the tank and pump and change those too.

If you read the link that romeomike gave you above half your questions would be answered .You asked what relay was what and in that link there is a picture of the relays with descriptions .
again ................ check it out there is alot of info there ........
