I think this is a computer issue. When I try starting my car, it starts right away, kinda. It’s like the engine half engages and all the lights on the dash and radio go crazy. Here’s a video: https://youtu.be/XdAeRB2bCGM

I am assuming it is a computer issue? Or do I need to call a priest for an exorcism?

Hello,

I watched the video, I looks like you may have low voltage. I would check the battery and the alternator output. It should be 13.5 while running? Low operating voltage can do what you are seeing.
The link below will show you how to test the charging system.
