What's the reason for the fuel gauge of Baojun 510 not moving?

[Barros]

The reasons for the fuel gauge of Baojun 510 not moving: failure of the fuel float (fuel level sensor); short circuit in the fuel gauge wiring, etc. Fuel float failure: If it's a car that's been around for some years, it's very likely an issue with the fuel float, which is the car's fuel level sensor. The owner can check whether the fuel level sensor plug on the fuel tank is loose, oxidized, or burnt; observe if there's any sticking during the sliding process of the fuel level sensor. Fuel gauge wiring short circuit: If the fuel level sensor is not the problem, then it's very likely an issue with the fuel gauge wiring on the dashboard. In this case, the dashboard should be removed, and a multimeter and a pin should be used to accurately locate and test the wiring corresponding to the fuel gauge on the dashboard.
