I have a 2010 Expedition el and have been having problems with the gas gauge and low fuel light coming on. I figured since I had 118k miles on it, the problem was probably the sending unit. Changed out the pump assembly and I’m getting the same thing. The fuel gauge will work fine some days and others I will get a low fuel light and the gauge will slowly fall down. Take the battery terminal off and it’s back to working for a while. Does anyone have a wiring diagram of the grounds for this. I have cleaned and reattached the ground to the body on the battery ground. I think a bad ground is the issue.
