GAS GAUGE NOT WORKING

2001 Buick Century • 120,000 miles

Guage either shoots to full, or drops down to empty.

When it's at full unplug the harness to the tank and see if it drops down. That would indicate a bad sender which is the most common cause.

Does the sender have anything to do with the gas tank and specifically the FLOATER? I was told the the fuelpump and gas tanks floater is the cause of this issue.

The sender IS the float.
