I'm not trying to be mean, just don't want someone to read this and think they can fix their Jeep in the same manner. This is a placebo fix. If the screws you took out were about 1/2 long (that's what comes from the factory), they screw into a plastic block about one inch thick. There's nothing there to short to. If you ever take one apart, you will see what I mean.
The reason people mistake the screws for something that is causing a problem is that when you disturb the harnesses, you cause an intermittent connection in the harness connector or solder joints inside the PCM to have a better connection.
There is a temp fix that sometimes produces the same results as moving the screws. It involves using zip ties around the connectors. This has worked for a lot of people.
So, the crank sensor apparently fixed your vehicle and you may have a pending problem with your PCM.
