Costs for evaporative emissions controls troubleshooting varies. The dealer has the best diagnostics tools using a Tech II. You could check all vacuum lines running from the fuel pump pod to include tank seal to the filler neck and charcoal cannister. From the cannister and vent solenoid the lines run to the purge solenoid at the engine area. Also, make sure vacuum is good coming from the throttle body to the purge solenoid. Other possibility is a defective fuel tank pressure sensor giving erroneous results to the PCM for the small leak down test.
