Alright new problem.

First test this morning was looking at fuse 4 and the cas relay. After 10 minutes of driving the ray was warm but not hot. Many videos say it should be hot. Fuse 4 was ok

Then, tested from the cas, terminal 21 and 22 for the starter. All good as seen by the first video. (*DISREGARD*) However there was a loud thud near the end which resulted in no power to the ignition. Car will not react to key presses nor key in ignition.

Edit: fixed it. Cas plug was not in all the way. Car is fine

Ok so next step is ordering a new relay. It will get here some time tomorrow, I also ordered a multimeter so that I may be able to watch the alternator as we crank to see if there a major drop in voltage. I can't imagine a bad alternator would contribute to the no start issue but who knows at this point.
