There is only one thing that causes this, and that is the guage sending unit in the gas tank.

Fuel gauge problem


Could be either one.
You could disconnect the harness at the tank and ground the gauge circuit to see if the gauge will go to full. If it does chances are the problem is the sending unit in the tank.

My fuel gauge floats from full to empty when I stop at a light! And its stays on empty until I drive for about five minute why is that? I can't get an accurate fuel reading!!


I have the same vehicle and my car actually was full of gas, registered empty & left me on the side of the road..It was the sensor in the fuel line that had to be replaced.

Just had our 2001 ford expedition's fuel pump replaced and the fuel gauge has since then not been reading accurately. What could cause this? I've taken my car back three times and was told that the fuel...


If the guage is reading but not accurately it may be the incorrect fuel pump for the vehicle or the float is may not be in the retaining clip all the way. Also possible that the float got bent during installation. Can you describe what the guage is doing such as reading full when its 1/2 full or jumping around on you?

My gas gauge seems to be acting up. When I get below half a tank the gauge will go up to full and back down again on it's own. It seems like it is only accurate when I put the car in park. what gives?


The float is what measures your gas levels. It is controlled electronically. There might be a loose wire or it could be going bad. You can usually get to them by moving the back seat. Others, the gas tank has to be pulled off. I hope this helps you.

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.

Fuel gauage isn't accurate, i drove 400km. and gauage indicates 3/4 tank full.why is this so.


The fuel tank probably got filled too much gas, and the float got bent, or the float was not installed properly, when the fuel pump was installed.

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.

Gas guage no longer works when below half a tank.


You are probably looking at dropping the fuel tank down and removing the float and sending unit ( all in one unit). Once it's taken apart, you may see that you can fix it or you may have to replace it.
