    Default 03 Yukon Denali CEL

    I let my 03 Denali run out of fuel and now the check engine light will not go off. Are the two related and what should I do?

    It's possible the two can be related. Make sure your gas cap is on securely once you have fuel back in it. Then have the check engine light looked at using a scan tool. If the gas cap was left off with the key on or cranked it will set a code.
