The problem is usually the crankshaft sensors.These are located on the front of the engine block and are kind of hard to get at.You have to do this from the bottom.Best done on a cold engine or expect to get burned from the hot exhaust.There are 2 of them and they need to be replaced as a pair.They are also both different so you need to be careful not to mix them up.I usually do one at a time.If you have the codes scanned you will probably have codes for the crank sensors in the pcm.Hope this helps and let me know if you have anymore questions.Good luck.

If it starts up for a few seconds and shuts off the oil pressure switch is to blame

Stalls when coming to a stop


Mine stalled when I stopped and it was the Idle Speed Motor. If it only stalls when you stop, I would check that before messing with the fuel filter or pump.

1995 Cadillac Seville SLS stalls out


It sounds like it may be time for a new fuel filter, try replacing the fuel filter first. The filter has a life of 30,000 miles or one year, if it has not been changed, good chance that it's the fuel filter. Take not that a dirty fuel filter will make your fuel pump run hotter and will shorten the life of the fuel pump which is the more costly repair of the two. Good luck and keep me posted, Be glad to help you get your car running 100% again.
