Solution
1. Preparation
  • Gather required tools and parts.
  • Disconnect the negative terminal of the battery for safety.
2. Inspect Fuse
  • Locate the fuse box, usually found under the dashboard or in the engine compartment.
  • Remove the cover and identify the fuel gauge fuse.
  • Inspect the fuse visually; if blown, replace it with a fuse of the same amperage.
3. Access the Fuel Sending Unit
  • Raise the rear of the vehicle using jack stands for safety.
  • Remove the fuel tank access panel (if available) or drop the fuel tank to access the fuel sending unit.
  • Disconnect the wiring harness from the fuel sending unit.
4. Test and Replace Fuel Sending Unit
  • Use a multimeter to test the resistance of the fuel sending unit. The resistance should change as the float moves.
  • If the resistance is outside the specifications, proceed to replace the unit:
    • Remove the fuel sending unit from the tank.
    • Install the new fuel sending unit, ensuring it is properly seated and secured.
    • Reconnect the wiring harness.
5. Reassemble and Reconnect
  • If the fuel tank was dropped, reattach it securely.
  • Replace any access panels that were removed.
  • Reconnect the negative terminal of the battery.
