You don't give the make model and year, but generally the gauge is controlled by a float in the tank. The gauge could be faulty, or the sending unit with the float in the tank.
When the gauge reads empty and you know you have fuel in the tank, a mechanic would check the connector at the tank for power and ground.

SOURCE: 2000 buick century custom. fuel gauge fluctuates

The sender unit has a fine resistance wire with a slider to read the level, the slider or wires are worn and making intermittent contact, the low fuel light is a seperate switch so it will still work.access to the sender is usually under the rear seat cushon, under the soundproofing and a cover, have a look and describe what you have .

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.

SOURCE: 2003 Impala fuel gauge used to bounce and now

most of the time this is simply just the float in the gas tank getting stuck had the same problem in my car. unfortunately you have to access the gas tank to fix, but it is an easy fix. hope this helps any questions let me know.

Fuel gauge will fall from half to empty or from empty to half


Sure sounds like a faulty sender in the fuel tank...

Way to check would be to remove the wiring from the sender when tank is low and gauge is playing up at half way , if the gauge falls it's the sender, if not it's the wiring...

2003 Chevy S10 had fuel pump replaced. When fuel gauge shows slightly below half, the gauge falls to empty and low fuel lights blinks. What could be causing this?


hi,

sounds like the sending unit rheostat(sending unit) has a bad contact or break in the resistance wire. inside the tank theres a float attached to an arm that goes to a small rheostat, like a volume control on a stereo. the rheostat is sending a scratchy signal or no signal to the computer and your getting these readings. that part is inside the gas tank, the part usually comes integrated with the fuel pump. the gas tank has to be lowered to fix it.

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.

I have a 1997 BMW Z3 roadster. I filled my tank drrove a mile and the gas gauge falls back to empty. What could possibly be the problem


Could be a short in a wire from your fuel gauge to the fuel tank where the actual fuel gauge sending unit is probably located.

How to test fuel gauge in dash 89 chev 2500 so I can tell if the gauge or tank unit is bad. The dash fuel gauge will change 1/4-1/2 tank overnight even if the truck has not been run.


To test the gauge,unplug the connector at the tank,the fuel gauge will go to full,then ground the wire to the fuel gauge,and the gauge should go to empty,I use a test light for grounding the circuit,to keep from grounding the wrong connector,when doing so,the test light will glow dim,and the gauge will go to empty slow.

Fuel gauge keeps going to empty and warning light


in side the tank on the side of the pump there is what thy call a sender not to be confused with the sending unit. The sender is atached to the float and tells the gauge how much fuel you have.

Gas gauge works than doesnt than works again


This is the sensor in your fuel tank, they have little brushes on them that run on a reostat. it is a common problem, I have been able to remove them and fix them, although the best option is replacement.
