I have a 2001 GTP coupe, and i will not start at times,it cranks and all but will not turn on. IT dose this now and then, hot or cold. i even replaced all 3 coil packs, for the reason that at the time that it did not want to start, i checked for spark from one of the plug wires, and there wasn't any spark. but that was not the problem. I need help, PLEASE. Dose anyone know what it might be?![]()
