When you fill the gas tank don't be topping it off. You need to stop filling when the gas pump nozzle clicks off the first time. Otherwise the fuel gets into the EVAP system, and could be throwing a code to make the check engine light to come on.

But it came on again this morning when I was driving it an I haven't put no gas in

Just have to have the vehicle scanned for codes to know what the cause for the check engine light to be coming on.
