you start with a smoke test to check for evap leaks. then you test the soloniods for operation and then have a scanner tool activate and de activate the soloniods to verify that the pcm is doing its job you obviously need a scan tool and a shop for this procedure. the easy answer is, there is no quick fix for this.
