Long term no power where crank no start usually is the EWS. It's stupid it didn't just block the crank.

You said you did EWS delete but undid? What do you see on scan of EWS module?

The only sensor I know that prevents a start is the cpk crank position sensor.

You mentioned no codes on cps. Of the dozen or so I've replaced only ones ever had a cps related code. They work -ish and cause an inherited unrelated code. Won't affect start but wanted to throw that out there in case you get it started and it likes to stall with no cps code.
