I have an 87 Carrera cabriolet in concours condition with one exception.Last winter my Carrera would not start - it would turn over, but notcatch. I went into full diagnostic mode and checked everything. It turnedout to be a corroded fuel pump fuse. During my attempt to checkeverything I bent the middle clip connection on the female side of thecrankshaft reference sensor when reconnecting it. I used a pair of needlenose pliers to straighten the connection out and all seemed well.This summer the car began to not catch again. However, after about fiveminutes of trying it started up strong and ran fine. The problem remainedconsistent until the other evening when the engine quit while travelingdown a road at 45 mph! All electrical power remained, but I could notrestart it for fifteen minutes. When it started it caught fine. Isuspected the reference sensor connection. I have tried to reproduce theproblem and then jiggle the connector. This appeared to work twice, buthas more often not made a difference. I can still get the car going aftersome cranking, but clearly something is wrong. During the winter Ichecked the fuel pump with a homemade switch and it worked fine - I canhear it activate now, so I believe the engine is getting fuel.The oxygen sensor also seemed fine, although I have not checked it again.I have ordered a new female connector housing for the crankshaft sensorfrom Porsche but have doubts about getting the wires out of the old one.Any ideas about what the problem might be and what I might try to correctthis?
