If The Guage reads full all the time, chances are that it is toast. You'll have to replace the Gas Guage with a factory or aftermarket replacement. Auto Wreckers often provide a cheaper alternative, if you don't want top buy new. Honestly.......Give your gas tank a kick! The float in the tank might free up for awhile.
MY 94 3.1 V6 HAD THAT PROBLEM THE DIFF WAS THAT IT READ ONLY UP TO A HALF OF TANK. WHAT FIX IT WAS IN THE BACK OF THE TANK THERE ARE TWO PLUGS PULL BOTH OF THEM OUT THEN SWITCH THE KEY TO ON YOU WILL NOTICE THAT IT WON'T READ GOOD OK THEN BACK TO THE PLUGS AND PUT THEM BACK IN. TURN THE SWITCH ON MORE TIME AND THAT WORK FOR ME.... HOPE IT HELPED
i have a 1990 ford ranger and my fule gauge always reads full, why?
Either the gauge is broken or the sender is broken.
BUY A FORD
In the gas tank
Defective fuel sending unit.
you should go to a car shop for that one!:)
gauge is broken
Check the ground to the tank. That may help
bad sending unit in tank, or short in wireing.
you need to replace the sending unit in the tank!
The fuel gauge on a 1985 Chevy Silverado will read full all the time if the sending unit is defective or the wire has come loose. When the tank is full, the sending unit normally shuts off which cause the gauge to read full.
Either the wire from the gauge to the sender is broken or the sender is bad.
