Check the ecm/fuel pump fuse, should be located under the hood, passenger side front, close to the relay pack. The fuel pump relay is in the relay pack, closest relay to the radiator. When in doubt, which relay is which, look at the wire colors at the connector, match with wirng diagram. Right now, I don't believe the relay is faulty, but you can check the circuits.

Also there should be a fuel pump prime connector, under the hood, It's just a test circuit for the pump. Should be located, driverside firewall, between the master cylinder and fender. Red wire with electrical connector, nothing plugged into it. If you use a jumper wire from the + bat terminal to connector, the pump should run. You don't need to use the ignition key. Use an inline fuse on the jumper.
