Check for power to the fuel guage (or for blown fuse, of course!) If that is ok, and if you can access the fuel tank sending unit, pull off the power wire (usually red or with a red stripe) and hold it to a known good ground. If the guage goes up to full, you have a bad sending unit or it isn't grounded well. If the gauge still does not move, it's the guage itself. Easiest fix is to replace the cluster from a junkyard vehicle "donor"
SOURCE: tail light are not working
I have no power to the tail lights, checked fuses they are good. Can I replace the relay and is it in the same place where the fuses are? Help me I can't figure this out.
