I have a 1999 tj that recently decided to go swimming. Not a great idea at all. So my dash lights work but gauges will not and I have read several of the posts to get an idea of what it might be. Yesterday I pulled the sending plug off of the gas tank to see if power and/or ground signals are there. When I pulled it the low fuel light came on which tells me the wire is still sound and that light has come on before when I get low on fuel. Wouldn't the gas level signal then still be intact and something else is the issue? If the low fuel signal is sending back information then wouldn't that mean that the ground wire is good? Thanks
