There is a red wire with a connector in the wire bundle near the fuel pump relay on the driver side firewall. That is the diagnostic test point for the fuel pump. Apply 12 volts (+ side) to that connector and the fuel pump will run if it is good. If it doesn't run you either have a bad fuel pump or a bad wire going to it.
