Gas gauge not working properly?


This is caused by a defective fuel level sending unit inside the fuel tank.

1987 Nissan Maximum gas hand doesn't work & transmission is reading full but it leaks sometimes


There are three fixes possible for the gas gauge....but I would have this troubleshot by a garage:

1. The gas gauge itself does not work anymore. It could have just finally "died". Problem is, you cannot replace just the gauge. It has to be the whole instrument cluster. Having a garage shoot power TO the gauge and then shot the gauge itself will let you know if the gauge assembly is bad.

2. The fuel sending unit is bad. This means the wiring to the gas tank fuel pump/sending unit is bad and does not work. The signal is not being sent to the fuel/gas gauge. This means the fuel pump assembly needs replacing.

3. There is a wire problem somewhere between the gas tank and the dash to the fuel gauge.

The transmission leaking but still reading full just means that there is plenty of transmission fluid in the transmission. The drips or spots you are finding are not enough to "read" low enough. Unless you have a HUGE spot of tranny fluid left on the ground, I would just think about a transmission fluid filter change. This way, a new pan gasket will be installed and fresh fluid filled to the proper level will be accomplished on your car.

If it has a new tank and the gauge has not been reading properly since it was installed and wont start now it might be out of gas.

1970 chevy nova gas gauge problen


Well friend, you know the dash gage is good cause that was a proper test procedure. Since your not getting proper readings it has to be the sending unit. Pull it apart and clean the rheostat with a pencil eracer and light pressure, the assemble it and try it again. if still nfg, replace the sending unit. they're cheap from any auto parts store.

I have a 2000 buick Le Sabre. gas gauge does not work properly. i filled the tank and the gas gauge reads full. and it works properly past half. then it starts flucturating. i disconnected the gas gauge...


There are three possibilities. The gauge could be defective. The instrument panel voltage regulator could be bad or not grounded or (most expensive) it might be the sending unit.

Both speedometer and gas gauge not working properly. Gas gauge giving readings all over the dial and speedometer starts to give proper speed then it reduces speed on meter until reading zero even though...


Hello: To correct this condition you will have to replace the cluster. After replacement the mileage and engine hours will have to be reset then the cluster will have to be programmed to your truck.

2001 chevy silverado 4.8 gas gauge not working properly


Fairly common problem with GM vehicles. The sending unit in your tank has a small circuit board that an arm is attached to which moves up and down according to your fuel level. This circuit board and arm are not making good contact. Unfortunately the only good solution is to replace this part.

Gas gauge shows empty after filling gas tank. Eventually the gas gauge will register the proper level.


The gauge circuit is shunted on most cars, this is wierd, but needed to stabilize the readings... Your description sounds like normal function. Drivers would complain if the qauge were to be instant, going around corners, starting, stopping, all move fuel, and the gauge would indicate this, cauing driver alarm...Been this way for ever, although yours sounds like it is on the far side of the scale...if it reads correctly after a while, you could replace everything and you would have the same performance.
