2006 GMC Envoy Denali: check engine light

Filed Nov 8, 2016 · Fuel system · 140,000 miles · KY

Initially, when the car was filled with fuel, it immediately indicated that the car was empty and the engine light came on. Once you used a couple of gallons the fuel gauge began working and the engine light went off. Just recently the system is not correcting itself and the fuel gauge will constantly go between full and empty so I never know how much fuel I have in it. Also the engine light is remaining on.

Initially, when the car was filled with fuel, the fuel gauge would automatically go to empty and the engine light would come on. After driving several miles, the gauge would correct itself and the engine light would go off. After months of this, the system does not correct itself and I never know how much gas I have - it constantly goes from full to empty.

When starting my vehicle and start to drive I notice 2 check engine lights pop on. One engine light has a arrow pointing down and the other just have the engine light symbol and the my speed starts to reduce a lot. I will pull over to the side of the road shut the car off wait for 5-10 minutes and crank it up and after maybe 15-20 minutes of driving it pops back on. I've had the mechanic to diagnostic machine and he has said the throttle body needs changing, had that done and the same problem came back. So I had my old one put back on and then the mechanic say maybe it's the gas pedal sensor. Had that changed and the problem is still their. I love my truck but I don't have the money to kep trying to fix this problem. I need help, from someone, please

After driving approximately 20 miles on cruise control I tapped the brakes to disengage the cruise control. The vehicle dramatically lost power and the check engine light came on. I was able to avoid other traffic and pull over on the freeway, I then drove off the freeway on the shoulder and into the nearest gm dealer at maximum speed of approximately 30 MPH. The problem was diagnosed several times resulting in rewiring of the throttle body connector and finally replacement of the throttle body after the third incident of the same issue. Loss of power and unable to proceed at more than about 30 MPH.

Fuel sensor failure in the gas tank. Causing the fuel tank to read empty when full, causing the SUV to stall when the tank is full, causing the check engine light to come one. This is a safety issue.

I've got a 2006 gmc envoy and the gas gauges never reads full. It's always readying either empty or full. I've been dealing with this for about 4 months now. Hoping that something would come of this before I just go out and have someone fix it. My check engine light is on due to this problem. Thanks!
