How long are you waiting?

Some of those take up to a minute to engage.

Find the actuator for the front diff
Its mounted on the frame I think
See if that moves when the engine is running
See if it has vacume when in 4wd
See if the vacume lines are damaged from the engine to tcase and tcase to actuator
Last thing to check is the vacume switch on the tcase
