2004 Grand Prix will not stay
My car cranks over but will not start. I had the
battery tested, ignition module tested and all
coil packs tested and all tested good. I
replaced all the plug wires and still car will
maybe your car is out of time.
Check your fuel supply line. electrical problem is one possibility but you have exchanged most of those parts already. You may not be delivering fuel to the engine.
is there a fuel filter in this year? if so, replace it. also, the crank sensor is sending a signal??
I'd suggest checking your fuel pressure and scanning it for trouble codes before you start replacing things.
