I then took an ohm reading like everyone suggested on the sending wire that goes through the trunk to tank. (I did not drop the tank) I took it right on top by the rubber boot. It read .06 on a fuel tank. Fuel gauge yet to come of empty. Any Advice?
I finally figured out the trouble with mine.....I had replaced the the sending unit, the o-ring clamp the holds sending unit in place was grounding out....I took oring off attached wires guage worked......I carefully put ring back on tapped into place gage still worked.......If you have changed sending unit, you might want to double check it.
