Replaced mine in a1994 today. Symptoms were sometimes crank but no fire. Fired when returned to run position. Some other times, no crank at all. I figured dirty contacts. On a 1994 there are actually two switches, the rotating ignitions switch at the end of the lock cylinder and a spring loaded pin go/no go switch which mounts to the top of the lock cylinder with two screws right near where the key inserts. Both switches wired to the one harness. I found the wiring for go/nogo switch too short so had to cut the plastic in the harness to get enough length to reach. Rotating part held by one screw. Not that hard to replace. When reinstalling the screw which hold it in place, take a piece of masking tape put a small hole in it, insert screw through the hole and then use the tape to attach the screw to the end of the screwdriver. Once installed, wiggle the screwdriver to pull the screw off the tape. The switch at the top of the cylinder is a real PIA though as the screws are under the dash gauges with only a little clearance. I was able to use a small straight bladed screwdriver to turn the screws about 30 degrees at a time and got them out. Wife stood outside truck and held switch in place with her finger while I reinstalled screws using a long needle nosed pliers and then used small straight bladed screwdriver again to tighten them. I have since found small 90 degree screwdrivers on Amazon which appear likely to work better on those two screws. I don't believe there's enough room for the typical small 90 degree ratcheting screwdriver.
This is what needs to be removed to do the job on a 1994: Column covers, kick panel, heater duct held in place with one screw above your left shin, then loosen the whole dash panel over the switches/radio/heater control to access the go/nogo switch at top of lock cylinder. That panel does not need to be completely removed, just loosened enough to provide access. These are the screwdrivers I think might work. Amazon product ASIN B07GNPRRVZ

) I had to use a mobile locksmith. No luck whatsoever with a dealer or a hardware store. I didn’t try the DIY key cutting machine at home depot or Lowes, the machine might work.
