More likley than not your plugs have to be changed, unless, they were cleaned with a spark plug sandblaster. The fouled out part of the plugs hides deep within the insulator chamber and cannot be cleaned without sandblasting. Therefore the spark, instead of tipping off at the electrode, tries to climb into the insulator chamber leaving a very weak spark. P.S. while changing the plugs, turn the engine over without them in to clear the cylinders. Thanks, Dana
Do you have an anti-theft system on this car. That is about the only other thing I could think of besides bad relay or fuse. Since crank sensor and module are good.
3.1 or 3.4 theres no 3.3 in a Buick, Chysler products , no GM next to the battery in the fuse relay panel theres both the relay and the fuse that powers the relay. The pumps fail more often thogh. find the relay remore it and change it with a different relay like the high beam and see if it'll run the relays do fail but if they do the cause is most often the pump drawing too much, Some times cranking the engine and pounding on the tank can ( wake-up ) the failing fuel pump but even if it starts the pump will do it again and it's truly bad. It may stop or not start next time stop on the road and not restart. Or could work awhile if you find the fuel filter dirty and a neww one releives the extra load on the pump.
what I do in the shop is find a computer that the numbers match and swap it out and try it if you can find a good salvage yard that may let you try it before you buy or alot of times you can get a used one for about 35.00 the other way is to remove it and open it up and see if you can smell that is was burnt or see any burnt spots.
