It could be a few things. First, start at the fuel pump relay. Make sure the relay is good and there is power there. After that, you will need to trace wiring to the fuse block under the hood and trace wiring in general to see where power is lost. If there is power to the relay, follow the power from the relay to the pump. Chances are you have a break in the wiring.
