Not the igniton switch, its the ingition cylinder and or the housing. The switch is not part of what you are really turning. It's connected to it via gears. The common problem is the key gets worn out and the tumblers wear also. Eventualy they do not line up right and will not make the "bar" drop in the cylinder to allow it to turn from the off positon. If you have the title in your name and the key has never been rekeyed or the code has been changed you can go down to a dealership with all of the info for the truck and they can cut you a key from the vin number. You can try that first before you put a cylinder and housing in it.

The Power control module may be your problem

jack up the rear end high and place chassis rails on stands. Remove wheels . disconnect brake hose to the rear and use a hose pincher to stop brake fluid leaking out . Disconnect the hand brake cable at a convenient point ( probably at the rear of the transmission. Disconnect the drive shaft at the diff pinion and lay to one side . Place the jack under the diff housing centre and take a bit of weight. . If you have leaf springs --undo the "U" bolts around the housing . If coil springs undo the track rods by removing all the pivot bush bolts. Lower the diff housing down and pull out from under the car. Make any changes you have to, to the other diff housing before placing it on the jack and placing it under the car Reassembly is the reverse process of removal..
