I just got home from school and back to the car. I removed the gas cap, checked the seal on it, and it seemed fine... checked that because I saw a post earlier AND because the instructor at school told me it was a possible vacuum leak. Got in and it started just fine. Left the hood open and listened for hissing sounds, but I did not hear anything unusual. Also, the check engine light was no longer on. So I get excited, put the car in drive, and it dies as soon as I let the pedal go. Just tried to turn the ignition on three times so fuel pump would absolutely be primed, turns over and over but no crank. I'm going to check the air filter now.
