Hello, my name is ***** ***** I'm here to help get your problem solved. Starter wire being shorted should usaully cause the 40 amp IGNA fuse under hood to blow. If good remove starter and verify pin 30 has voltage at all times, 86 should have gorund, and 85 should have power with key in start position. 85 gets power via purple/white wire which goes to transmission range switch. Transmission range switch gets power via purple wire from 10 amp crank fuse on fuse box under hood. And 10 amp crank fuse gets power via yellow wire from ignition switch. So you will need to do testing to see where voltage stops and go from there. You most likely have a blown fuse or bad ignition switch. Here is a wire diagram to help with test. Let me know if you have questions or run into questions, you can reply to this answer at any time without additional fees. Thanks.
