UPDATE!

The bike now runs, BUT only for a moment.

The problem was the previous owner wired the fuel pump wrong. This led to the fuel pump and lights working, but no communication to ECM, and hence no spark. Having fixed the wiring, the bike now starts – briefly.

If any throttle is applied, the bike immediately dies, if any throttle is applied while cranking, the bike won't start. When it does start, it idles for ~2 seconds. IF the idle adjustment is maxed out, then the bike can stay on as long as it remains over 7k RPM. Anything below and it immediately dies, and if idle adjustment is changed it also dies.

So, now I am at a loss. There is no codes, now I can get into dealer mode, and everything seems fine electronically.
