Other than replacing the sensor which is part of the fuel pump assembly inside the tank, you may have loose or corroded connections in the wiring just outside of the fuel pump/sensor position on the tank. These connections are exposed to water/salt conditions from road spray. May the force be with you!

2006 GMC Envoy XL gas gauge reads empty


Gas gauge readings are controlled by the sending unit on the fuel pump. I do not believe there is a separate fuse for any particular gauge. In order to fix it, you have to remove the fuel pump from the gas tank, determine if the float is stuck or the sending contacts are out of alignment or dirty. Some can be repaired, but most are not serviceable. Remedy: replace the fuel pump and sending unit assembly. I would first inspect the wiring from the fuel pump connector(s) to make sure you have good connection and wire integrity.

Fuel gauge is not reading properly 2006 Mercury Mountaineer


Fuel gauges are not meant to be precision instruments. You might want to fill up a 2 gallon can and drive the car until it runs out of fuel to see how low the gauge will go before it's really empty. Use the 2 gallons to get back to a filling station.
I once spent three working days trying to get a 1972 Chrysler to read full when it's full, half when it's half and quarter tank when the tank has a quarter amount of fuel. The customer did not want to accept anything else, but in the end all I did was to get close, not exact.
It is possible that the fuel float in the gas tank is "drowned", that is, the plastic float might have a slow leak and some fuel found its way inside. This will cause the float to submerge slightly and give you a low reading. To check this you will have to remove the float unit from the tank.
In any case, if you feel up the job (not easy) remove the float unit from the tank and manually move it up and down while checking the meter reading. You can bend the wire holding the float to correct misreadings.
Personally, I wouldn't bother, just be aware that when the reading is low, feel safe that you still have enough fuel to get to the next filling station.

Fuel gauge reads past full all the time


when the tank is full the resistance is low so the power through the gage make is read full
as the tank empties , the resistance increases so the less current means the gauge reads less until empty there is little or no power , the gauge reads empty
simple check , turn the ignition off, no power , no gauge reading

Why do my gas needle go from low fuel light on to exactly how much gas I have in the tank?


I'm not sure I am understanding your question. The low Fuel indicator light comes on, depending on how sensitive it is set, when you have between 2 and 5 gallons of gas left in the tank. This also depends on how accurate your fuel level sending unit is reading the fuel level in the tank. The low fuel level light depends on the level of fuel in the tank itself but other than using that sensor it has nothing to do with the fuel gauge itself. The fuel gauge may or may not be accurately showing the fuel level.

2006 GMC Envoy XL gas gauge reads empty after filling continues reads empty and the light is on then the check engine light came on what can be the problem how ca i fixe it to save mesome $$$


It is most likely your fuel level sending unit has gone bad. It sits inside your fuel tank to tell the fuel guage how much gas you have in the tank.

The sending unit for the gas gauge is in the fuel tank and part of the fuel pump module, it is not sold seperately. Price is around $350.00, 2 hours labor to install the part.

Fuel Gauge reads empty, but tank IS full


the float in your gas tank seems to have water in it....water is heavier than gas, that's why gas floats on top of water....try putting something like HEAT in it to dry up the water in your tank....
