SOURCE: fuel sensor gauge

you will need to replace the fuel level sensor.(sending unit) it is in the tank and is hooked to the fuel pump. you can buy seperatly from pump. you may finf it easier to remove the bed if you have some help. it is six or eight bolts and harness unplugs then you can get right to it.

SOURCE: 1999 Monte Carlo fuel gauge stopped working

Hi there. If the fuel gauge is the only one acting up, its probably a loose or corroded wire on top of the gas tank where the fuel pump sets in. It could also be a loose wire on the back of the gauge, which is easier to get to so you could always check that first by popping off the dash pannel and pulling out the instrument cluster and looking for a broke wire on the back of the fuel gauge. But if I had to bet I would guess its on the other end by the fuel pump. Worse case sinario, maybe a bad sending unit.

SOURCE: 2002 Chevy Suburban: Fuel gauge reads empty, tank is half full

Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.

Good day
You have to look in under the dash and make sure the connections at the back of the cluster is in place. If that is all good then check the fuse box and make sure all fuses are in place and working correctly.
Good luck.

I got a 2001 Chevy Venture and fuel gauge always stays on full


The problem is in the fuel sender unit in the tank. It sounds like the float part of the sender unit is binding when it's at the top (when tank is full) and hangs up there till it falls back down when tank is near empty. It will likely have to come out to be checked, fixed, or replaced. Good luck.

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.

Fuel guage stays on empty and low fuel light stays on,no other problems


You might have a leak in the float in the fuel tank sender unit (the float should sit on top of the fuel and feedback info to the gauge - the fuel gauge staying on empty might mean that the float is either leaking or it is stuck).

1989 Saab 900 low level fuel light


You don;t say whether the fuel gauge is reading accurately, or whether it's always on empty. If the gauge is always showing empty, it's most likely a problem with the sending unit in the fuel tank. Check the resistance across the two terminals of the sending unit.

On a C900, the fuel sender level unit is separate from the fuel pump and located on the right side top of the tank, accessible by removing the trunk floor lift up panel (the pump is located on the left side top of the tank.
Possible problems are: electrical line off or broken, float not working (it's fairly delicate); or gauge not working.

Test the resistance of the sending unit with the lines disconnected, the resistance should be 2.6 to 3.8 ohms full tank, 63.3 to 67.5 ohms empty tank; and test for voltage across the top of the sender unit, if no voltage, that's likely the problem!

If the gauge is otherwise reading accurately (showing 'full' for a full tank, etc) then the problem is likely a gauge malfunction and can be simply replaced.

Good luck!
