Fuel tank gauge does not work?

If your fuel tank gauge is not working, it may be due to a faulty fuel level sending unit, a broken connection, or an issue with the gauge itself. Start by checking the vehicle’s fuse related to the fuel system, as a blown fuse could cause the gauge to malfunction. If the fuse is intact, you may need to inspect the wiring and connections for any damage. If these checks don’t resolve the issue, consult a professional mechanic for further diagnosis.
