Maybe, maybe not, try fiddling with the shifter and see if the shifter needs to be in the sweet spot for car to crank or not.
Install test light connected to battery positive and other end connected to #86 of starter relay (relay removed) and fiddle with going to park and neutral and see if you get the test light to light up.

What are your symptoms? You could test the switch by bypassing it. Go from pin two at the switch to a ground with your test light while trying to start the vehicle. That switch is just providing a ground when in P or N.

Does it ever start at all?
ive seen more of these jeeps that had anti theft issues, than any other make and models , which it wont start, if thats the case.
Has anti theft been ruled out?

You should not have power at 86 in the crank position. The relay coil should act as a load and drop the voltage to near zero there. I believe you have an open somewhere after 86.
When you touched your test light there, in the crank position, it should have grounded that circuit though, unless you are using an LED test light?
