Have you smoked the system? Without a snap-modis, and a smoke machine, its almost impossible to figure out faulty evap components.

Not exactly sure what smoking the system means and what is a snap-modis?

When you smoke the system, there is a tool used to fill the evap system with smoke in order to find a leak. The Snap On modis is a very expensive diagnostic tool that can be used to activate, or deactivate system components.
