Which type is it, ESOF ( Electronic Shift on the Fly ) or MSOF ( Mechanical Shift on the Fly ) ?
Best to check by jacking the truck up ( taking safety precautions, parking brake, chock the wheels, jack stands, etc ), turn the key to the run position and place into 4WD.
If the front drive shaft turns, the problem is in the transfer case.
If the front drive shaft does not turn, the problem is in the front axle.
I would suspect the front shaft does not turn, and the most common cause of this is the vacuum motor on the front axle, the vacuum lines to it, or the vacuum solenoids.
The vacuum shift motor is what locks the front wheels in, and without this action, the PM does not get the confirm that the truck is good to go, and illuminate the cluster indicators ( 4x4, and if 4L the Low Range lamps ).
There are 2 vacuum solenoids, one is 4WD one is 2WD ( to move the motor one way or the other ).
Start with checking for vac on the vacuum motor ( actually it is a diaphragm ). The pink line should have vacuum when in 4WD, the blue line should have vacuum when in 2WD. If not, time to work back towards the solenoids. Use a short length of hose on the vacuum solenoids, and retest.
If still missing vacuum on the 4WD solenoid, I would suspect it is bad, but best to test on the other side of it, to make sure the vacuum reservoir ( mounted behind the battery box ) is supplying vacuum to the solenoids.
This is just the most common cause, best to confirm with the 1st test above, to know if you should look to the trans case, or axle.
This is what the vacuum shift motor looks like on the front axle
These are the vacuum shift solenoids

put a ground strap from your transfer case to your transmission. also with someone listening under the car with the key on but not running put your foot on the brake, shift to neutral and turn the selecter to 4x4 low and see if you can hear the actuater respond
