What is your question?
My 2010 cadillac srx engine light is on. Diagnostic test says pressure in EVAP system during a non purge condition. Probable causes: purge or vent solenoid failure, plugged EVAP canister condition, Failed EVAP pressure sensor. Tried changing gas cap, butbut engine light came back on. Wheen I out gas in it, ot takes a few secs to start. Any suggestions?

Pull Evap line going to purge solenoid(behind throttle body) put your finger over where hose connected to solenoid. If you feel suction on finger at idle.....replace purge solenoid and clear codes
