It cranks fine and the temperature was all over the place when I got it going, so I assumed it was the temperature sensor, so I replaced that. Now it only starts if I unplug then plug the crank sensor back in, but it’s not guaranteed every time? When it does start it runs completely fine with no problems at all and no warning lights are present. I’ve put I diagnostic tester on and it’s showing no faults at all.

I think you found the problem, the crankshaft angle sensor which when it goes bad will not leave a code. Here is the location so you can change it out to see what happens in the diagrams below, and a video for the repair on a similar car.

Check out the diagrams (below). Please let us know what you find.
