Why does my gas gauge needle never go below 3-4 tank?

My gas needle goes between 3-4th and over the F. Never goes below 3-4th tank. Also I know I use more gas then $22 sometimes. When I try to fill up. The Gas pump shuts off at $22 like its full.

I would guess the fuel level sending unit is malfunctioning, deposits sometimes build up on the resistor pack, or there is and open circuit in the resister pack, does the fuel gauge needle do a full sweep from empty to full and back when the ignition key is turn to the run position? This is a cluster self check mode, if it fully sweeps than the cluster is ok, I would suspect it needs a fuel level sending unit which is located in the fuel tank as part of the fuel pump modual but usually can be serviced separately

SOURCE: car will not accept gas

try pulling back a little on the nozzle, the tank has an anti rolloverball in the pipe and this sometimes cause it to shut off when the nozzle is stuck all the way into the filler pipe

No, there is not a fuse for this. Unfortunately, you have a bad sending unit. In order to replace the sending unit you have to drop the gas tank. Sooo............drive it more to get rid of all of that gas and it will be easier to put back up.
please remember to rate this solution.

SOURCE: gas gauge shows empty after filling gas tank

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.

I sounds like you have an electrical problem with the dashboard. It will have to be pulled and checked.

I had the same problem with the gas tank on my 95 mustang. You are going to have to drop the tank. There is a rubber seal where the filler neck goes into the gas tank that has failed and must be replaced. You are losing even more gas than you think. Everytime you make a left turn gas is sloshing out through that bad seal.

Gas guage moves back and forth from emty to full with gas in it


it sounds like the level sensor on the sender (fuel pick up pipe in the fuel tank) is getting stuck. the level sensor is a float that is attached to the sender, and you will need to remove the fuel tank to get to it.

hope this helps.

1999 Pontiac Grand Am Fuel Problems


The gas guage has a sending unit in the tank attached to the pump, there is a small circuit board on it that has smal"fingers" that send the signal to the guage.These get worn off and thus sends a false reading to the gas guage in the dash. The gas tank must be removed and a new unit put in to solve the problem. I had to do this repair to mine. As for the gas issue, just try pulling the nozzle back out of the filler neck when putting gas in, sometimes the overflow tube gets plugged up and won't allow the air to escape as the gas goes in the tank, making the gas pump think the car is full, pulling the nozzle will allow the air to escape. Hope this helps.

My gas gauge needle won't move after i filled it up


for some reason and I don't know why the sending unit is sticking in the gas tank the only thing I can recommend to try is to go to Walmart and get a bottle of STP gas treatment also read on the bottle to make sure this is the kind that has a lubricant in it for the fuel pump try this first before any major repairs are made because the button could also be sticking on the sensor to let you know how many miles to empty
