Pontiac grand prix 3800 no start or random shutoff
I have an issue. I've seen this asked on here
several times too so it must be common.
However.... I have replaced the fuel filter,pcv valve ,
plugs , wires, and crank sensor but the problem
still exists. Someone told me I may not be getting
fire that I may have bad coils or icm problems but
it runs fine when it starts. Ive exhausted all options
other then fuel pump...I think. Can someone shed
some light on this dull ass parade of mine??
What came up when you scanned it for trouble codes?
had the same problem,,spent a fortune trying to find the problem,,no garage could pinpoint the problem,,it was the electronic ignition switch below the coils or what the coils sit on,,,the flat electronic plate,,so far ive replaced it twice,,it just about drove me nuts to find it. my car has 376,ooo on it and drives like a dream
