Check the fuel gauge fuse first, as it could have blown and caused the issue. If the fuse is fine, then it could be a faulty fuel sending unit. Try cleaning it and if that doesn't work, it may need to be replaced.

H

Another possibility could be a faulty ground wire connection. Check the wiring and connections going to the fuel gauge and make sure they are secure and not corroded.

T

If all the above steps do not solve the issue, it could be a faulty fuel gauge itself. Consider taking it to a mechanic for a proper diagnostic and repair.
