Repair Instructions

Replacing the Fuel Pump

Safety Precautions
- Park the vehicle on a level surface, engage the parking brake, and disconnect the negative battery terminal.
Relieve Fuel System Pressure
- Remove the fuel pump relay and start the engine. It will stall once the fuel pressure is relieved.
Access the Fuel Pump

Remove the Fuel Pump Assembly
- Unscrew the retaining ring or bolts holding the fuel pump assembly in place. Carefully lift the assembly out of the tank.
Install New Fuel Pump
- Place the new fuel pump in the assembly, ensuring proper orientation. Reinstall the retaining ring or bolts.
Reconnect Fuel Lines
- Attach the fuel lines securely to the new pump.
Reassemble Access Panel or Seat
- If removed, reinstall the access panel or rear seat cushion.
Reconnect Battery
- Reconnect the negative battery terminal.
Test the System
- Insert the fuel pump relay back into its socket, turn the ignition on to prime the system, and check for leaks. Start the engine and verify operation.

Troubleshooting Electrical Issues

Testing the Fuel Pump Relay
- Use a multimeter to check for continuity and proper voltage at the relay terminals while cranking the engine.
Repairing Wiring Issues
- Clean any corroded connectors and repair damaged wiring as necessary. Use heat-shrink tubing to protect any exposed wire.
Confirming Power to the Pump
- If the fuel pump does not activate, check for power at the pump connector while the ignition is on.
