check engine light is on.Digital display read "check gas cap" once and the check engine light wont go off.After I pump gas it takes 5 mins for my car to start. Found out that this was because its taking longer for the pressure to build back up in the gas tank.
check engine light comes on after gas cap indicator comes on and stays on
