didnt unplug anything besides whats in the tank. could have pinch something putting the tank back up. Its a pain to put gas in it. (nice and slow)

I believe....if you look above the drivers side tail pipe(the end of the pipe),,,you'll findthe solenoid and the evap canister....little round solenoid ,,,looks kinda like a little fuel pump with a plug in the end of it....make sure its plugged in,,,and all the evap lines are on .....also need to check all fuses....I'm at home and dont have a wiring diagram to look at ,,but can tomorrow...
