    drivers info center has check gas cap message on it. I checked gas cap it was tight and heard the 3 clicking sounds. I still am getting message of check gas cap on the driver info center,I purchased a new gas cap . I am still getting message and it tripped the check engine light. OBD TESTER, is giving code of P0449.

    The check engine light came on after replacing the fuel pump they said it was my gas cap. Turned out they didn't reconnect some tube when fuel pump was replaced. I was getting gas fumes inside the car on occasiona also.

    gas cap vibrates loose and makes check engine light come on. Bought new cap and it still does it. Even with a lock gas cap.

    After tank is filled, fuel gauge goes to empty and engine light comes on. It does this for a few days and finally clears up. Chevy people say it needs fuel level sensor replaced (1000.00)
