Ok, this is driving me up a wall.
Backround
So i finished the swap, odb2 all oem except for the fuel tank sensor.
The car ran great, idled perfectly, no issues whatsoever.
Then it began to have trouble starting, starting and idling fine after two or three cranks.
Lately it was taking me longer and longer to start, until it left me stranded after trying to start it for about an hour.
Resolution
The battery is a fresh bmw battery, the starter spins the motor great.
I checked compression on the motor, 200,200,205,195,192,190, so thats not bad.
I replaced the loud, but working, 318is fuel pump, with an e36 m3 fuel pump, that had much more noticeable spinning torque when i bench tested them both.
I made sure the ews system gets power at all times and when the ignition is switched, also made sure to position the transponder chip properly inside the anntenae ring( which prevented me from initially getting the motor running after the swap).
Spraying starting fluid is weird because it might stumble for a second or two, but then it won't ignite during later sprays.
I tried to check for spark, but apparantly the coil needs to be grounded along with the plug itself, so i'll recheck for spark.
I replaced the crank position sensor with a cheap 40$ duralast, noticed the old sensor had a hairline fracture and was leaking oil. Still nothing:(
The pikes peak code scanner gives me a few codes for oxygen sensor related issues, but nothing that relates to a no starting condition. No camshaft sensor code or crankshaft sensor code for that matter.
Im so overwhelmed that i can't figure out whats wrong.
The symptoms sound like it could be anything from a bad ecu, ews system being missaligned somehow, ...
I don't think its a bad ecu, because im able to read codes from it.
I really should get some fuel pressure gauge to see if its near the required 50psi from the schrader valve on the fuel rail.
Besides all that, i really could use some advice.
Should i order oem cam and crank sensors to be sure, Should i just have a known good ecu flashed for ews delete?
