A defective hose from the valve to the intake was forum member Luckyman01's problem, I believe. If it turns out the purge valve itself needs to be replaced, Glenn said none of the valves are all that expensive, and that was music to my ears.

The various valves in the Evap system are simple valves either one way vacuum operated or electrical. Both very simple to test...
The rest of the system is composed of hoses and a canister so also very easy to test.
The major issue with the Evap system is access to all of the components.
If you have a schematic to the system and understand the layout....
you should be able to test much of it with something like a Handy Vac...with it you can apply vacuum and see if it holds over a period of time. If it does then you know the parts of the system your testing have no vacuum leaks.
