There's probably a relay that may control the fuel pump and the rst of the fuel system. I'd go to the local auto parts store and purchase a service manual, i believe it's only about twenty dollars. Good luck.

Aaron, I had the same problem. It is the most expensive part of course the computer. I replaced everything as well till I replaced it. They are remanufactured and have had problems with them as well. I am on my third one now at 200k miles. Oh and by the way it does not show up on the diagnostic check. Good luck

i would check the fuel pressure first if it is in the good ranges then your pump is good. have you checked your spark plugs and wires? if not i would, if bad replace. otherwise i would have the ignition coils checked to find out if they are working correctly. that is all i can think of. good luck
