Float in tank is stuck or defective gauge Sounds like the sending unit is stuck in the full position.
Where is it stuck? on full or empty? if on full you got a bad ground, if empty you got a bad float.
check sending unit in tank and check gauge for proper operation and connections, and grounds
Yes, but if your gauge is showing full when it isn't, then it's probably either a bad gauge or a stuck floater in the tank.
Float could be stuck in the tank or the ground wire on the tank is broke.
Bad connection, blown fuse, or the float in the tank is stuck.
The gas gauge sensor is most likely stuck. It is inside of the tank and over time it will get corroded.
More often than not, a fuel gauge problem is usually a faulty fuel gauge sending unit in the fuel tank.
The float that tells your gauge how much gas you have may be stuck or there is a problem with the system that sends that information to the gauge.
the sending unit may be stuck
You first need to discover what is wrong. It can be the gauge, the sending unit (the part that measures the gas in the tank), or some associated wiring.
The fuel gauge could be getting improper signals from the fuel sensor. The sensor is located inside of the fuel tank.
