Hello just recently bought a 03 corolla at 58,000 miles I hit recently 61,000 miles my warranty just ran out. The check engine light was coming on so I took it to the toyota dealership on the computer it said emission fault they said I need a charcoal filter gas cap and vsv valve. The was working then yesterday I was about to go out and the car wouldn't start the motor. The battery wasn't dead it still had juice but it wouldn't complete the cycle of the car starting up. Could somebody please tell me whats wrong
