Vanagon Fuel Pump Relay Location at Dustin Silva blog

Vanagon Fuel Pump Relay Location. The fuel pump relay should still be open. Check for battery voltage at the fuel pump to the two wire terminals at the fuel pump (brown is ground the other is power). I’ve tested the fuel pump directly to the battery and it works. The fuel pump is controlled by the fuel injection system’s electronic control unit (ecu) via a fuel pump relay. Based on what i understand the ecu relay should turn ecu on in the run position, which in turn will give power to the fuel pump relay. The wires to the relays tested out fine and there is power to the leads. If you do not have >10 volts, supply battery voltage to the power wire, and ground to the ground wire to see if the pump runs. When the ignition key is turned to. This is easily done by removing the fuel pump relay (placement varies according to model) and running a jumper wire across where the outputs. If you have >10v the fuel pump has likely failed. Assuming your 87 is like my 84, the fuel pump relay is on the drivers side of the engine bay in the box above the coil. Once the engine starts and stays running, the ecu simultaniously supplies a ground to the fuel pump relay causing it to close;.
