The tank purge valve is in front of the passenger cyl head. Did the hoses and electrical connector get plugged back into that? With that message, sounds like either a tank purge hose did not get plugged back in, is leaking, not seated, or gas cap itself leaking. I'd take that purge hose off the purge valve and reinstall making sure it makes a positive click as it seats.

After you find the leak, it takes two drive cycles (cold start to operating temp) without the leak to clear the message. So after you fix something, give it a few days to see if the message goes out.
