The EVAP Vent solenoid gets the ignition voltage from the Eng1 fuse in the engine compartment fuse block (PNK wire from the solenoid terminates at pin E3 on connector C3, bottom side of fuse block). The PCM then grounds the control circuit to energize the solenoid (WHT wire, pin 45 on connector C2, PCM). First, check for battery voltage on the PNK wire at the solenoid with key ON and then go from there?
