Vats system
Re: Vats system
before the starter wouldn't turn at all. But the security light still worked and the fuel pump would prime like normal. But after I tapped on the starter with the jack handle through the headers, the starter started turning but that's when the security light and the fuel pump stopped working. And it also has no spark now. But also 5 minutes before all this started, I actually started the car and it worked just fine.
Re: Vats system
The bare wire is the purple 12 volt input to the solenoid. With a VATS problem (key or theft deterrent relay) that wire would not be hot with the key in the “START” position. You were trying to connect the 12 volts from the main cable from the battery to the starter (the heavy black wire on the stud to the left) to the stud in the center for the solenoid. A spark may have damaged the purple wire.
But that places the jack handle very close to the PCM ground stud. And the ground wires and the purple solenoid wire are in the same harness bundle, along with the knock sensor and right bank O2 sensor wires. I'm just GUESSING somehow 12 volts hit the ground stud and back-fed the PCM, damaging it. Or it simply burned through the thin PCM ground wires.
You definitely need to examine the ground stud and the wires for signs of damage. Then try and scan the PCM to see if it’s still functioning.

Re: Vats system
I gave you a link to the ground stud photo in post #13…… didn’t you look at it?
Whyever or wherever you were randomly poking around with a jack handle, there's a chance you did electrical damage or mechanical damage. Shorting the 12 volts from the battery to the solenoid is generally done with a screwdriver to bypass the ignition switch.

Re: Vats system
You have a car that is "special". Unfortunately or descriptively that means it requires special treatment. You can buy a cloned Tech 2 from China for about $300 (takes a few weeks) ... or you can buy a scanner that can do some diagnostics... for about $400 (CP9185) ... or you can buy an ALDLcable.com scanner cable for about $80 with shipping and tax and use my app on your pc for free. If you don't think it is worth it, I hope you sell the car to someone who does.
