What happens when you remove the purple wire from the starter?

Power going to what?
Does the starter stop when the wire is disconnected?

Yes it does. Actually. With the purple wire on I can't leave the battery (+) connected. That is why I had it off in the first place.

Now you have to determine where that wire is picking up voltage. It could the the ignition switch or the transmission range sensor or shorted wiring in between. I would probably try first shifting it into drive and see if it still cranks. If so, unplug the range sensor at the transmission and see if that stops it.

I've already unplugged the ignition switches (both plugs). I will go try putting it in drive and see what it does. Where else can it pick up voltage?

You don't have to try it in gear now. That was to test the ignition switch. Unplug the transmission range sensor and see what that does.

Ok, there are 2 plugs on there. I pulled the smaller plug first and still had power at the purple wire. Pulled the bigger second plug and now there's no power to the purple wire.

You'd better make sure nobody has modified any wiring or tapped into any of those wires anywhere. This appears to be pointing to a bad range sensor switch but that still isn't making a whole lot of sense because there shouldn't be any power there for anything with the key off. It should be examined more closely by an electrical specialist.
