What have you checked? Have you tried using a smoke machine to see if you have any leaks, or any of the valves are working properly?

smoke machine, no. i havent done it that way simply for the fact that i cant get my hands on one, but i did peak around and use starter fluid to see if it would rev and blah blah.

likely a broken vacuum line to the evap purge solenoid, or a bad solenoid. common problem.

you are experiencing a vacuum leak.
