    I have the same problem. I have a 2006 GMC Envoy - Each time I feel the tank, the pointer either remains on the empty (Yellow Light On) or it gradually goes up to full after a few start and stops, then it drops again to empty with beep and the yellow warning light on again. I just replaced the gas cap with a brand new from a local dealer. It did not help. It is frustrating. Please help. George Ogbona

2006 ENVOY fuel guage reads empty after fill up. What is the cause and how to rectify?


Usually I find there are two common causes for this problem. If the gauge goes to empty after a fill up but then starts to work and be fairly accurate as the fuel level in the tank drops then it's often the fuel level sending unit which is attached to the fuel pump module inside the tank. I have seen some guages go bad also [actually the servo motor that runs the gauge] but usually the gauge will stick in one spot and rarely move or go to either end of the scale and stick there. A good shop should be able to determine the cause of your problem pretty quickly. Hope this helps and good luck!

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.

Gas guage-oxygen sensor?


The oxygen sensor has nothing to do with the fuel gauge. There are two possibilities for the gas gauge error, first it could be the in-tank gas level sensor or it could be a defective stepper motor which drives the gauge. A professional scan tool can determine the fuel level being sent by the in-tank sensor, if that disagrees with the gauge, then the stepper motor needs replacing.

Gas gauge problems


Common problem on the 03-06 Envoy instrument clusters for the fuel gauge to go out. It's usually caused by one of two main problems, either the stepper motor on the cluster's circuit board is going out or the sending unit on the fuel pump is going out. Check out this blog post about the problem - Envoy fuel gauge problems

2006 GMC Envoy XL gas gauge reads empty after filling, then slowly moves up after driving but will continue to lose pressure until it reads empty and the light is on, then the check engine light came...


Sending unit. Its all one unit including fuel pump, float, ect. The check engine light is because of the high or low resistance in the unit. Let me know if you have already fixed.. You have to drop the tank to get to it also.
