    My 99 grand prix died out when I was driving the other night it didn't want to start but it did crank. I did some research and found that it could be the cranksenser or cam senser. I replaced both and still nothing so next i replaced icm and both pcm and nothing I checked the fuel pressure it was good fuel pumped worked and even changed out fuel filter. I am at a loss and don't know whatelse it could be....does any one know what it could be!!

    Are your fuel injectors pulsing? You can have great fuel pressure at the rail and no injector will keep you from running.
    I drink..so consider that when reading my posts.

    Hm. Coils?
    Irridium spark plugs last 100k mi and work just as well as copper. Copper is a waste on N/A and only lasts 15k mi. Don't use Platinum.
    Use 195* tstat unless you can thoroughly explain why not; 99.9% don't need a lower temp.
    Almost any oil filter, ever, is of higher quality than ACDelco. Spend $6+.
