Okay, then going by what you have stated about replacing the "whole EVAP system" your problem has to be a defective computer then. As long as you're sure that there are no leaks and that the purge and vent valves are working.

Please understand that I don't know your skill level or tools
you have to assist us. Also understand that I can't see, smell,
hear, or touch the vehicle either, so your patience is
appreciated. JA is a great Q/A site, but it does not replace a
repair shop. So please don’t shoot the messenger if I have to
deliver bad news:)
pops up. I don’t get credit for helping you until
you rate me

Thanks, Ron
