Re: 94 Fuel Pump Problems

Most oil pressure senders/switches, are backups to the fuel pump relay.....

Way to check the circuit, is disconnect the harness to the fuel tank.....4 wire harness......2 wires for the fuel pump, two wires for the fuel sender to the fuel gauge....you attach a test light to the harness half, going away from the tank....attach it to the 2 wire fuel pump circuit.......

Turn key to "on", don't crank....should light for 2 seconds and then go out.......now crank the vehicle.....light should be on steady.....if this is the case, and you have no fuel pressure, you need a pump....
