I disconnected the wire from the sending unit, The gauge still goes to full when turning the key on. This tells me that the wire is grounding out on the body some where. What do you all think? Cleon

Try grounding the wire at the sending unit and if the gauge goes to empty then your wire and gauge are good, and your problem is the sending unit or the ground for it. All tests the key needs to be on. Last edited by dens41; 10/20/14 09:28 PM.
