Engine + Driveline / E36 M42 won't start/stals if cam sensor is plugged

« on: September 15, 2010, 12:46:54 PM »

Pulled the cylinder head, confirmed, bended 4 intake valves and 2 on the exhaust, going to fix it and will report as soon as she's operational again, will make some improvements this time since the head's out. Her last run http://www.youtube.com/watch?v=ZoxvNgaDOKs
after this pull I've parked her on the garage and didn't start again :p on the video on 4º gear could see some power loss after 5000rpm guess she was warning me of the bended  valves :p this run was versus an E36 318is, mine has a few mods I would describe with pictures later,

cheers

Nothing new keeps doing the same, already checked every wire back to ecu, the crank and cam sensors plugs on the e36 only fit on teh correct place, not possible to plug the cam sensor on the crank plug.. with the cam unplugged the engine doesn't take longer to fire, looks the same as always, can't get out of this I'll pull the head next week to check valves and compression rings.

hmm you give me an idea, I'll replace the crank pulley tomorrow, the idle it's puzzling me too, If unplug the ICV the idle goes down but keeps going up an down but between 1000rpm and 1500rpm.
Yes the coils are matching the cylinders, thats no insult sometimes we just check the complicated things and leave simple behind! I've checked:
intake manifold, unassembled it to the bone to check all the sensors plugs and signals between the plugs and ECU, replaced gaskets too to eliminate any micro air leak that could possible exist, next tested every sensors the cam and crank were bad bot working just to eliminate possibilites I've replaced them with brand new ones same way but same result. Fuel pump, FPR and relay check, engine main relay, DISA, Knock's (replaced both with brand new) TPS, AFM, lambda, injectors, coils, spark plugs, engine temp sensors were replaced with new ones too, and tested with another working ECU.
I've checked the distribution chain guides and chain tensioner.

At this time it sound's like something were wrong on the internals bended exhaust valve maybe, but she's not showing signs of that just looks something wrong with the electronic, a hell of a mistery here!

Cam and crank sensors are brand new, cam has 1250 and crank has 550. Timing is correct checked it twice, stomp test says 1444 all the time even when plug the cam sensor and stals it records nothing... It's an euro e36. Vacuum lines all new already check with carb cleaner spray everything nice, fuel pressure at the pump it's good, installed a new FPR and hasn't changed nothing keeps the same

Hi, I've a weird one on a 93' M42 E36, so has been replaced knock sensor's, camshaft and crankshaft sensors, and the engine only starts with high idle and coming up and down between 1000rpm and 2000rpm with cam sensor unplugged, if I plug the cam sensor the engine stals and gives a missfire with a big bang on the exaust..! And won't start with cam sensor plugged, just gives a 1 second work and stals with missfire on the exaust. I've checked every sensors, injectors, fuel pump etc this is weird cause she was running pretty well and become like this with no explanation.. AFM replaced, Idle valve replaced, engine temp sensors on the head replaced, double checked everything and no solution yet..!

Any suggestion?
