Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle’s battery to prevent electrical shock.
  • Ensure the vehicle is parked on a flat surface and secured.
2. Access Fuel Sending Unit
  • Tools Required: Socket set, screwdrivers, fuel line disconnect tool (if necessary).
  • Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
  • Disconnect the negative battery terminal.
  • Remove the rear seat or access panel to reach the fuel pump assembly.
  • Unbolt and carefully lift the fuel pump assembly from the tank.
3. Inspect and Test Sending Unit
  • Inspect the fuel sending unit for corrosion or damage.
  • Use a multimeter to measure resistance across the sending unit terminals; it should vary as the float moves.
  • If the resistance is constant or out of range (typically 0-90 ohms), replace the sending unit.
4. Replace Fuel Sending Unit
  • If necessary, install the new fuel sending unit.
  • Tools Required: Torque wrench for proper fastening.
  • Reinstall the fuel pump assembly into the tank, ensuring it is properly seated.
  • Torque the mounting bolts to the manufacturer’s specifications (check service manual for specific values).
5. Reassemble and Test
  • Reconnect any fuel lines and electrical connections.
  • Reinstall the access panel or rear seat.
  • Reconnect the battery terminal.
  • Start the vehicle and check the fuel gauge operation. Ensure it responds correctly when adding or removing fuel.
