How to Wire a Fuel Pump on a 1984 Nissan 300 ZX

The Nissan 300ZX is a sports car manufactured by Nissan from 1984 to 1996 in the United States. The 1984 Nissan 300ZX has a 6-cylinder 3.0-liter engine, and some models have turbocharged engines. All versions of this vehicle use fuel injection, which requires a highly-pressurized fuel system. The fuel pump in the 1984 Nissan 300ZX is within the fuel tank, so you must remove it to install the fuel pump.

Instructions

    1

    Start the engine and disconnect the fuel pump relay in the fuse box. Wait for the engine to stall, and attempt to start the engine three more times to ensure you have completely relieved the pressure in the fuel system. Turn the ignition switch off.

    2

    Disconnect the electrical connectors for the fuel gauge and fuel pump in the trunk. Place a hose into the fuel tanks filler tube, and siphon as much fuel as possible into a gasoline container.

    3

    Detach the ring for the fuel filler neck on the fuel tank with a socket wrench, and remove the right rear wheel. Disconnect the protectors for the fuel filler tube protectors and the fuel lines to the fuel tank.

    4

    Support the fuel tank with jack stands, and loosen the bolts for the retaining straps on the fuel tank. Disconnect the fuel tank and remove it from the vehicle.

    5

    Turn the retaining ring for the fuel pump counterclockwise with a hammer and brass drift. Remove the retaining ring, and lift the fuel pump out of the fuel tank.

    6

    Install the new fuel pump by performing steps two through five in reverse order. Replace the relay connector in the fuse box, and fill the fuel tank. Start the engine, and check for fuel leaks.
