Need some help from Automotive gurus out there, mainly FORD gurus. I have a 2008 Lincoln Navigator L and about two months ago I was going down the road and all of a sudden the gas gauge went to Empty and it is stuck there. Today I replaced the fuel pump and sender unit in the tank, installed the tank back up and still its doing the same thing. I thought for sure it was the sender unit giving me problems. A few minutes ago I check the old fuel pump sender unit with a meter and I am getting UP and DOWN resistance as I raise and lower the arm. So there is nothing wrong with the sender unit. I got online and been reading that FORDS have what is called a Anti-Slosh Module behind the cluster. So, I take out the cluster panel, there is NO ANTI-SLOSH module in these Navigators or at least I can tell because there is no module on the cluster panel. So I went ahead and ordered a used cluster panel a few minutes ago because I accidentally broke the plastic piece on mine. I will know if its the gauge itself once I get the used panel in the mail. Also the LCD panel shows ---- miles to empty and I cannot change it, it will not let me change anything on the LCD panel because its stuck on ---- miles to empty. So I am asking any FORD guru is they may know what would cause the gas gauge to be stuck on empty like this? I am at the point I am lost because myself and my brother in-law figures if it was a ground the fuel pump would not be working as they should be on the same ground. Any help is appreciated...
