Re: Where is the fuel pump located in a 1985 fiero
From autozone.com:
The Fiero is equipped with a electric fuel pump and gauge sending unit mounted in the fuel tank. The pump is serviced and a complete unit by removing the fuel tank.
REMOVAL & INSTALLATION
CAUTION
To reduce the risk of fire and personal injury, it is necessary to relieve the fuel system pressure before servicing any fuel system component. If this procedure is not performed, fuel may be sprayed out of the connection under pressure. Always keep a dry chemical (Class B) fire extinguisher near the work area.
- Disconnect the negative (-) battery cable.
- Relieve the fuel system pressure.
Remove the fuel pump fuse from the fuse block located in the passenger compartment. Start the engine and run until the engine stops due to the lack of fuel. Crank the engine for 3 seconds to ensure all pressure is relieved.
- Drain all the fuel from the tank using a suction pump.
- Raise the vehicle and support with jackstands.
- Disconnect the wiring from the tank.
- Remove the ground wire retaining screw from under the body.
- Disconnect all hoses and filler neck from the tank.
- Support the tank on a jack and remove the retaining strap nuts.
- Lower the tank enough to disconnect the fuel sending unit wires.
- Disconnect the fuel line, vapor line and return line.
- Remove the tank from the vehicle.
- Remove the fuel gauge/pump retaining ring by turning the cam lock ring counterclockwise using a spanner wrench such as tool J-24187.
- Remove the gauge unit and the pump.
To install:
- Inspect the fuel pump attaching hose for any signs of deterioration and replace if necessary. Also, check the rubber sound insulator at the bottom of the pump.
- Push the fuel pump assembly into the attaching hose.
- Using a new O-ring seal, install the pump assembly into the tank.
- Install the cam lock ring over the pump and lock by turning clockwise with a spanner wrench J-24187 or equivalent.
- Support the tank on a suitable jack.
- Raise the tank enough to connect all fuel and filler hoses.
- Connect all electrical wires to the pump and tank.
- Raise the tank and install the retaining strap nuts. Use new sound reducing pad if they are damaged. Check all connections and wire to ensure proper installation before refilling the tank.
- Refill the tank with unleaded fuel. Reconnect the negative (-) battery cable.
- Start the engine and check for fuel leaks and gauge operation.
