are all the electrical connections intact to the transfer case?

Or are they ripped off? Is your shift linkage bent or broken? what

happens when you grab the shifter and shift it?

Crawl underneath and have a look to make sure your linkage is

intact and adjusted to shift properly and engages transfer case all

the way in to position(invite a friend((slave)) over for beer and

get them to shift it in and out while you watch the action). There

is a contact at your shift linkage(similar to the one that lights

your brakes when you press the pedal) that when shifted into four

wheel drive turns light on, is it there and functioning(take a

digital multimeter and test for power shift it in and out of four

wheel drive?

Most importantly get a hanes manual for your truck it will help

a great deal. I think your problem is simple, and you should check

all the things i told you above first.

i am not a mechanic by trade but i have rebuilt a few vehicles

in my day and that's what i'd try.

Most likely a vacuum leak. Check the lines around the injector

pump. Paid dealer to fix mine and this is what they found.
