Anyone seen the problem of their '92 SL2 dieing a lot while driving (maybe two or three times in a trip of 10-15 miles. You pull over to the side of the road (scared to death of being rear-ended) and it will restart ok. Idles ok, but dies while driving or sometimes at stop signs. No particular warning.


Anybody had the same symptoms? How did you track down the culprit?


Thanks for any help you can give.

If you don't have a check enging lamp on you probably have a crank sensor that is failing. That and a fuel pump areusually theonly two things to cause a stalling problem with no codes. When it stalls and you try to restart it watch the tack needle and see if it moves. It should move to about the 400 mark during cranking but if it cranks and the tack needle won't jump up at all it's the crank sensor not sending a signal to the pcm.

 

rick, a crank sensor wont trigger a CEL?

 

Saturn are funny, if the crank sensor goes down the car just thinks,hey you shut the car off. It can produce a code if it goes out of its calculated resistance range but usually it just wont produce a signal and the car can't tell the dif between you shutting it off and stopping the signal anda faulty sensor stopping the signal. You figure it should produce a code ,kinda major fault, but I'v done loads of them with no codes,no tack signal is the dead giveaway.

 

may need a tune up, check ignition coil pack for corrosion
