fuel gage does not work, sending unit is ok, intrument cluster in new. whats the problem
i was told it can be the wiring harness between the fuel tank and the instrument cluster. how can i get part #'s and a diagram?
Wiring harnesses do not fail unless damaged or tampered with. I assume that you checked the sender out of the tank with an ohm meter if you say it's ok. Have you hooked up a scan tool to read the fuel level indication from there? Each individual loom should have a tag taped to it somewhere - you are talking about a lot of wire. Check the continuity of your loom first. Ground the sender to see if the cluster indicates a full tank. Most of the time, it's the fuel pump module (pump and sender) that has failed.
sending unit checks out and fuel gage always reads empty. theres 2 plugs on the instrument pannel. which plug is for the sending unit and whats the pin #'s of the wires into the plug. so i can see where my signal is broke between the tank and instrument cluster.
