The first thing i would do is turn on the ignition switch and ground the terminal marked as TH SW, normally the one on the top terminal on the relay. If I could hear the solenoid engage, then I would go for a test run and see what happens. If I heard the relay and not the solenoid, then I would look at the solenoid. If I heard nothing, I would jump the terminal on the other end of the relay to battery and see if I could hear the solenoid, thus confirming the relay is the culprit.
