This may mean there is corrosion on the wires of the in tank sensor, or the float arm is sticking. If you pull the sensor out of the tank and move it through its stroke a few times it may get better, I t may need a new sensor, if you ground the wire at the tank the gauge should move to check it.
I have known some car gauges to come good just by using a fuel addidive, which cleans up the corrosion in the tank sensor.

Guages not working,


If all voltages checked ok,then most probably its faulty instrument cluster board on which gauges are connected.Yes if cluster circuit board looks ok,then also it can be faulty.Somewhere there is minute short or burn on board then such prolem arises.
Also check the fuse box.One under hood and other under dash.Inspect each and every fuse and see if all are fine or not.

Gas gauge is moving up to full when i give it gas


Sometimes those gages go bad, or it could be the float on your sending unit is bad, that is in the gas tank, I have an older model truck that can be on empty and I can put like 10 dollars in it and it will show like it has a full tank, and we know with gas prices these days that isn't much gas lol, but more than likely it's sounds like to me that your gauge is faulty.

Gas gauge sticks to full what could be causing this it is a 2000 buick regal


Look for a problem with the fuel level sensor wire or a bad fuel level sensor. It could also be a failure right in the fuel gauge. Your model probably uses a direct metering (analog) gauge*. These have wire-wound resistors inside that sometimes burn out or break. If the low fuel warning light comes on when it's supposed to, then the problem is the gauge itself.

*Some of the newer GM models starting in 2001 have replaced analog gauges with digital circuits using stepper motors to drive the gauge needles, and they've had reliability issues with the stepper motors.

Fuel gauge is acting erratic. How do you replace the fuel sending unit on a Buick regal 2000?


you must remove gas tank, take out sender then reinstall in reverse order..

Gas gauge was just under 1/4 tank, I filled up and the gauge did not register full. after driving for approx 30mins the gauge slowly moved to full.


There is a small float in your gas tank something like the one in your toilet tank(no I'm not kidding).Its position regulates an electrical current and based on its resistance gives a reading on your gas gauge. My best guess is this float got a bit stuck in the low position and it shock free after some time on the road.This is more common than you would think.Keep an eye on it and if it freezes in empty position or sometimes full position it will need to be replaced. Hope this helps,good luck.

Gas guage not working on Buick Regal 2001? Stays on Full most of time. Sometimes it will drop to empty.

1999 buick when fuel gauge drops below 3/4 it is is not accurate


i dont know the specifics of a Regal, but usually, when a needle fluctuates too much, is because the float gauge in the gas tank is worn out, or its mount became loose. You cant see that effect on a full tank because the instrument needle and the float are pegged against the stop.

My gas gage is either on full or once in a while 2002 buick regal


there is a float in your gas tank kinda like the float in your toilet. Sometimes they stick and if the bell goes off then back.. it prob. from the gas splashing in the tank. I wouldnt' be concerned too much.
