Fuel gauge is full, low fuel sign is on

Hello,

This sounds to me like you have an intermittent or poor electrical connector in the circuit that goes to the fuel pump and the fuel level sending unit to your vehicle. In the diagrams below I have included the engine management wiring diagrams for your vehicle showing the fuel pump and fuel level sending unit as well as a pinout diagram of the fuel pump electrical connector, and guides on intermittent and poor electrical connectors, and how to probe an electrical connector for testing. You will have to use a Digital Multi-meter [DMM] to do these tests, so here is a link below explaining how to use one, if needed:

Please go through these guides and get back to us with how everything turns out.

Thanks,
