Wow this was one hell of a ride, great job by everyone involved. @J-Herkel your persistence and cool head paid off, well done sir.

I definitely considered setting it a blaze a time or 2.. but I also needed to get to work so had to keep at it! Appreciate it!

I felt the same way a few years ago when my throttle body harness took a schit. After several weeks of agony I finally found a hack job splice job at the pigtail under the wire loom that failed. Really proud of myself and the members here that kept me going. Great forum and members.

Well, anyone still following this thread?? If so, quick update. Ended up having to replace the starter after all last weekend. Went to start it and again, nothing. Everything was getting power as it should, grounds were all good, so I took a long ratchet extension amd a hammer and beat on the starter. She fired right up. Replaced it that day. Worked great for a while. Later that evening, did it again. Went to start and nothing. So now I know my relay is getting good ground, my starter is good, everything else is good. The problem is a loose connection somewhere in my fuse box. I'm not sure if it's under where the box plugs in, if it's on the board or a terminal in the box. Anytime it does it, I have to pop the hood, wiggle the fuse box latches slowly until i hear the fuel kick on and everything in the engine bay come to life, then try and start it. Usually after a few times, I can get it. Whenever it does it, it throws a "service air bag" message and throws the Theft deterent dummy light, but once I get the connection right, it all goes away and it starts. Seems to me like it's either a loose wire or terminal. Where within the fuse box area, I have no clue. But for now, at least I know the problem and can get it started within a few minutes if needed. Just wanted to update you guys. Local U Pull It junk yard is slap out of fuse boxes and says they sell alot of them. Online they are $400. Ugh.
