Check the fuel pump relay fuse in the front fuse box. If the ends of the fuse holder/fuse are corroded badly enough or if the fuse has gotten hot enough to weaken the tension on the fuse, the relay will not get power and thus not run the fuel pump. If that is not the problem, try putting one of the other relays in place of the fuel pump relay (the red one). They are all wired the same way, the red fuel pump relay is just a heavier duty unit.

Good luck!
