Put a code reader on it should tell you a code for powertrain

P0449 control vent valve/solenoid circuit malfunction, This code necessarilly deal with replacing the vent solenoid it about the circuit,the evap vent solenoid circuit may have rub through on the frame (located on the back of the fuel tank),it can also be the connector,the vent solenoid itself,or the connector

get a new gas cap your evap sytem isnt working if the gas cap doesnt work then you might have a leak and check your EVAP purge valaves

NO,the abs light being on is telling u that there is a problem with the abs electrical circuit. in no way will it keep your engine from turning over.

when you filled it up all the time did you keep filling even after the auto on the gas pump went off. in other words did you keep putting in gas to round the pump up to a round number. If so you could have pushed raw gas into a little filter and that will give you the same code. i seen it on moterweek, hope that helps.

look at the gas cap seal

you might have the brake shoes adjusted out too much, back them off a little bit and far as the sensor goes, its located on the fuel rail where the injectors are.

call GMC with your vin in hand and they can tell you.
