Did you hook up the ignition switch correctly? If not installed with the key in off position and tang in second slot this will happen.

Will have to remove the ignition switch in order to check it and then re install it.

i just found out if your truck locks in 4 low check the wire hardness next to the fuse box under the hood brake fluid will eat through the wiring and make the truck act funny and never diengaugr the 4 low to 2 wheel
