First check if there is change in resistance on fuel level when you add/remove fuel and if there is short ciurcit when there is low fuel.
After that check continuity from dash to fuel tank connector.
Wires are runed from tank to driver side fuse box and from there go to dash.

Thank you, i know there is a red/white cable disconnected that runs to my trunk, but i do not know what it is. Will gonna check my wiring then
