On your car this sounds like an opportune time WYIT to replace the crank sensor. Don't know if you have to measure and set depth of sensor to toothed ring on flywheel or there is a magnetic pick-up or a gap in the flywheel ring but ... if you do ... this seems like an ideal time for some preventative maintenance.

FWIW I've pro-activley replaced mine on both my E30 [front of motor, easy to do, only one sensor] and E39 [back of motor under intake, access from bottom, PITA sorta] BMWs. Less than 1 "C" note for part and labor is free + and good POM [peace of mind].
Well, the car is back together and it won't start. No, I didn't buy new sensors ($180 a pop from 944online.com--this will be more like 4 c notes when shipping is added). :XX But maybe one or both went bad when I pulled them. The one way in the back was really stuck but good.

I'll double check all electrical hookups, etc. I also snapped a vacuum tube on the master cylinder while trying to get the old sensors reinstalled. I am ready to go hi order on the car, cut it up and sell it for parts. I'll keep the fuchs, though.

Any ideas on what may be wrong?
