    Yes i do have the same problem.

    I have an obd2 (gadjet to read the codes when engine light appears). After refueling it hat happenned that the fuel meter went crazy. But after a few days it dissapears. the code was referring to the fuel level in the tank. However, the code for the knock sensor, even though i erase it reappears after about ten miles of running. I havnt replace it yet. But i supposse I am due!!!

    I have the same problem, The check engine light comes on after I run the car for about 15 minutes or so. The light goes off if I let the car sit for a little while(more than 24 hours). But I got the light checked (at autozone) and its says the problem is the knock sensor, the thing is the car runs fine until the light comes on then it seems like it is bogging down. I didn't think it was the knock sensor because I also had a cylinder 3 & 4 mis-fire code previously until I replaced the plugs. Anyway I ordered the sensor and will put it in this week, I will report back if that fixes the problem.

You need to check the codes in the computer. Under the steering wheel on left hand side there are two plugs green in colour plug them together with the ignition off. Once together turn ignition but dont start motor the check engine light will flash in pattens which can be found at this web site: http://legacycentral.org/library/literature/codes.htm
There are instructions also on this site hope this helps

Check Engine light comes on and gives a 463 code


This ultimatly will be a problem with your fuel pump. The actual code references the fuel sending unit voltage.. I suspect that your fuel gauge is not operating properly either. The fault is likely with the fuel level sending unit, but on most modern cars its built into the fuel pump.

Good luck.

Gas gauge goes to empty and then full after fillup


very well sounds like the sending unit in the tank. Try running some octane booster and fuel injection cleaner in tank of the truck to loosen any deposits on the float.

SOUND LIKE FUEL PUMP GOING BAD.YOUR FUEL LEVEL SENDING UNIT IS ALSO GOING BAD ITS PART OF THE FUEL PUMP ASSEMBLY.FIRST HAVE CAR SCANNED TO SEE WHAT TROUBLE CODES IS.REPLACE FUEL FILTER AND FUEL PUMP RELAY FIRST THEY ARE CHEAPER ROUTE THEY COULD BE THE PROBLEM.BUT FUEL PUMP COST BETWEEN $300.00 TO $700.00 THAT WHY CHECK FILTER AND RELAY AND HAVE IT SCAN BEFORE BUYING ANY HIGH PRICE PARTS.IF FUEL PUMP GOOD I BELIEVE YOU CAN BUY FUEL SENDING UNIT SEPERATE DONT HAVE TO BUY WHOLE PUMP ASSEMBLY BUT CHECK AROUND SOME AUTO PARTS PLACES WILL MAKE YOU BUY THE WHOLE FUEL PUMP ASSEMBLY JUST TO FIX THE FUEL LEVEL SENDING UNIT.

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.

Check engime light comes on and off


If you hear any ticking or knocking inside the engine do not drive it. You could change the oil pressure sending unit if there's no noise, most times that will fix the problem. It is advisable to put an external mechanical pressure gauge on there, either temporary or permanent...then, you can read the actual pressure...
I prefer gauges to lights because most time lights (either temp or oil) tell you "you have just blown your engine", instead of warning you when a problem is just beginning.
