Spark+Fuel but no start--S50

[Steven]

update-- well not really. I sprayed some carb cleaner into the intake and nada. All i got was the engine turning over and once again a short fire. Seems like it only fires the first time I try to start it of the day...

Atleast your car isn't frozen into the ground. So close but seems so far.

[Steven]

No one?

Since I rebuilt the top end of the motor, could this be a timing issue? I think it's all correct, but honestly it seems like I've checked everything with nothing to show for it...

[Steven]

This is to help diagnose the problem so you can see what I'm getting

If you aseembled it with the proper vanos setup tools its almost impossible to f up the timing.

If you r3vtard styled the install without the proper tool set it will be wrong yes.

If the bs litmus test of starter fluid = car doesnt fire then your wiring = wrong.

If the car wont fire all the time on starter fluid then your spark plugs are just not doing anything.

Back to square one:

Water temp sensor
Crank position
Power and ground at dme/ injectors/ coil


Bs test shows all; if engine doesn't idle on brake cleaner than your shit is not wired correctly.

Unplug afm and tps and iac to make sure they are not mixed up or bad.

The starter fluid thing you'd said contradicts itself... If it isn't firing then my wiring is wrong yet, if it isn't firing I'm also back to square one....?

Also, it was timed with BMW tools.

Think simple:

If your dads car didn't have gas in the tank it would fire up every time on starter fluid.

Don't disable dads car; just stating the logic.

Disconnect everything in the engine harness and check each plug by pulling back the rubber insulation and cross checking the wire colours with the bmw ETK manual.

If you did everything perfect by ETK it should just fire.

I did a s52 obd1 e34t swap a few years ago and my shit wouldn't fire. Turns out the CRANK sensor plug was plugged into the oil pan level instead crank sensor. Duh!!!

Doesn't the crank sensor not send fuel or spark if it's disconnected? I'm getting both... And it's coughing... Soil can't imagine my wiring is wring although I'll check.

No idea. Your car dont run could be anything?

are you getting a CEL with the ignition in the ON position?

[Steven]

OMFG something weird is going down with my engine... SO. When I try and turn it over normally, it just coughs and dies. You all saw the video, HOWEVER, when i tried to compression test it (took out the fuel pump relay and compression tester in cylinder 1) it started right up. weird. OKAY. Put everything back together and same thing as before cough die. Take out the relay again and bam starts up. wtf. Seems like it's pumping too much fuel into the cylinders and is flooding it when it is trying to start, thus making it die....


And yes i do get a check engine light with the key in the ignition

Also I rechecked my wiring and found a couple wires mixed up. None of them should've effected starting though. Fixed them and still nothing happening.

A few things.
1. post pictures?
2. you said 95 M3? EWS ecu?
3. does the fuel rail have a FPR on it? Late 95's have it under the frame rail, and not on the fuel rail.

What pictures do you want? I have about everything.
Yes. 95 s50 out of an m3 Red label DME with turner tune for 21.5# injectors and 3.5" maf
Yes it does have that. I think i have it hooked up correctly although, it could be wrong. I put the small hose coming out of the underside of the manifold onto it.

So what happens if you unplug the MAF?
