If you put power to that solenoid and nothing moves, it's not working. You say it makes a clicking sound, so maybe it's just stuck. Maybe try cleaning it really good and test it again.

Some part of that solenoid should be touching the throttle. That is the part that should be moving. When energized, that solenoid holds the throttle in the proper location for your truck to idle. When you turn off the key, the solenoid de-energizes allowing the throttle to essentially starve the engine for fuel. That combined with cutting the power to the coil is how the truck shuts off. The solenoid isn't really required for shutting off the truck; it just helps prevent your engine from dieseling (running on a bit after shutdown.)

Sounds like your solenoid is not pushing the throttle to where it needs to be and when your engine warms up and the choke comes off, the throttle drops down too low and starves the engine for fuel.

Good luck and I hope this helps,

Mike.
