First you need to figure out why the fuel pump is not comming on. Becaus that is your main and more than likley only problem.
Being that you replaced the relay already I would have to say that you may need a new pump. If you need to know how to change it you can follow this post that I made on how to do so.

Also if you need a low milage pump Morad Parts Company - 3800 Motors, Transaxles, & Stock Parts has one. Ask to speak with Eric and tell him Parker From TDCRacing sent you.
That should do the trick if not let us know.
