My 300zx decided to identify as a 1 cylinder v6. So I went through the ignition system and fixed 3 major problem. My harness being cut, my PTU being shorted and unusable, and my popped ignition coil. Hope this helps guys.

Here is the write-up I referenced as I went through my diagnosing process. Made this way easier for my brain to understand.
