2001 Pontiac grand am 2.4 but my fuel pump and fuel filter is new and pressure relay fuse works what else could it be? It runs and then it just cuts off while your driving but it will start back up sometimes right away and sometime after u sit for a while.
Any codes in the computer?Also when it doesnt start for while what are you loosing spark or fuel pressure?

If its not loosing ethier then are you loosing injector pluse?You have to be loosing spark the correct fuel pressure or injector pluse those are the top three. There are others but those are the top ones. When it wont start is the security light on solid or flashing?
