Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Disconnect the negative battery terminal to ensure safety.
  • Relieve the fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
2. Access the Fuel Pump
  • Depending on the model year, access may be through the trunk or under the vehicle:
    • For access through the trunk:
      1. Remove the trunk floor cover and spare tire.
      2. Detach the access panel covering the fuel pump.
    • For access under the vehicle:
      1. Safely lift the vehicle using jack stands.
      2. Remove the fuel tank shield if applicable.
3. Remove the Old Fuel Pump
  1. Disconnect the fuel lines from the pump (use safety glasses to prevent fuel splashes).
  2. Disconnect the electrical connector from the fuel pump.
  3. Unscrew the retaining ring or bolts securing the pump to the tank.
  4. Carefully remove the fuel pump assembly from the tank.
4. Install the New Fuel Pump
  1. Place the new fuel pump into the tank, ensuring alignment with the fuel sender unit.
  2. Secure the pump with the retaining ring or bolts, tightening to manufacturer specifications (typically 15-20 ft-lbs).
  3. Reconnect the electrical connector and fuel lines.
  4. Replace any access panels or shields.
5. Final Checks
  • Reconnect the battery terminal.
  • Replace the fuel pump fuse and relay.
  • Turn the ignition key to the "ON" position a few times to prime the fuel system before starting.
  • Start the engine and check for any leaks around the pump area.
