Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Access Fuel Pump

Remove the rear seat or access cover (if applicable) to reach the fuel pump assembly.
Disconnect the electrical connector and fuel lines from the fuel pump assembly, ensuring to have rags to catch any fuel spillage.
Remove the retaining ring or screws securing the fuel pump assembly in place.

3. Replace or Repair Fuel Pump

If the pump is faulty, remove the old fuel pump from the assembly.
Install the new fuel pump into the assembly, ensuring it is oriented correctly.
Reinstall the retaining ring or screws, tightening them to the manufacturer's specifications (usually specified in a repair manual).

4. Reassemble and Reconnect

Reconnect the fuel lines and electrical connector securely.
Reinstall the access cover or rear seat.
Reconnect the negative battery terminal.

5. Test the System

Turn the ignition to the "ON" position to prime the fuel system, then check for leaks at the fuel lines.
Start the engine to ensure proper operation and listen for any unusual sounds.
