Are there any sensors for your 4 wheel drive on the tranny that stop it from engaging?

[Edit]

Answer

What kind of vehicle do you have, motor size etc.

Answer

It does depend on the vehicle but I am having the same problem with my '92 chev K1500 and have been told that there is a switch on the transfer case that activates an actuator on the front differential it may be one of those things or both

Answer

If it is an older style truck it is probably the cylanoid. thats what mine was anyways
