95 3-4 Posted May 19, 2007 Report Share Posted May 19, 2007 I have a 1992 Buick century, 3.3 259,000 miles and it has begun stalling and not restarting once it warms. When it is in its stall and no start mode it has no spark and no injector pulse. I figure it is the crank sensor anyone concur ? Quote Link to comment Share on other sites More sharing options...
1990lumina Posted May 19, 2007 Report Share Posted May 19, 2007 Sounds like a bad crank sensor since it will work when it cools off. Could be a bad ECM too, but that'd be the last resort! Quote Link to comment Share on other sites More sharing options...
joey b Posted May 19, 2007 Report Share Posted May 19, 2007 get a DMM. on the 2 plug harness that goes to the ICM (it is purple and yelllow) test the resistance while cranking the car. I'm willling to bet that it is the ICM and not the crank sensor. The crank sensor is only a 5 inch long magnet. Nothing special about it really.
