Console Fuel Gauge
The console fuel gauge is always stuck on full. No matter if there is power to it or not, battery unhooked, hooked, wires at the tank hooked or unhooked, including the ground that goes to the strap mounting. Nothing changes it, I can manually move the needle back towards empty but it just returns to full.
Any thoughts to this? Diagnostic approach?

What happens if you disconnect the wire in the trunk going from sender to fuel gauge and ground the wire going to the gauge with the key on.

Nothing, even with zero wires hooked and the battery disconnected. Key on or off makes no dif. Gauge just sits pegged on full even if it is hooked to absolutely nothing. Hooking everything up makes no difference either.

You have 12 volts to the fuel gauge?
Also check the fuel tank float assembly and see if the grounding terminal on the float assembly has a good ground to the chassis. If you have 12 volts and good ground then culprit could be the float assembly. |

Did you take a ohm reading at the sending unit by touching one end of the meter to the wire coming out of the sender and the other to the sender body?
If you grounded the wire going to the gauge and nothing happens either the wire going to the gauge, the gauge or there is no power going to the gauge. Check continuity from wire going in trunk to wire at the back of the gauge
