If your fuel gauge is not working, there are several potential reasons for this issue: 1. Faulty Fuel Sending Unit: -The fuel sending unit is a component in the fuel tank that measures the amount of fuel and sends signals to the gauge. 2. Faulty Gauge or Instrument Cluster: - The gauge itself or the entire instrument cluster may be malfunctional. Electrical issues, such as a blown fuse, could also be a factor. 3. Wiring Issues: -Broken or damages wiring between the fuel sending unit, gauge, and instrument cluster can disrupt the communication and cause the gauge to malfunction. 4. Bad Ground Connection: -A poor ground connection can lead to inaccurate readings on the fuel gauge. Check for loose or corroded ground connections. 5. Fuse Problem:
-A blown fuse in the vehicle's fuse box could disrupt the electrical circuit that powers the fuel gauge. Consult the vehicle's manual to locate and check the fuse related to fuel system.
