No start, HELP!!!!!!

Ok, so I have a 2004 converted to a 3V
Today I changed the cam sensor and road test and it was fine. The car came with an SCT tuner and the check engine light was not illuminating, so I programmed the car back to stock. After that the car will not start. I checked the fuel pump out and all wires at the connector are getting power to them. I can't find any wiring diagrams anywhere. I am starting to lean towards the ECM being no good.
Any other input would be great

Have you tried reloading the tune again? Or even reloading the stock tune again? Maybe there was a hiccup when refreshing, or maybe you turned the key off too soon by accident.

Tried multiple times. All 7 wires at the connector are getting power to them. I even tried updating the firmware on the tuner and its not even recognizing the tuner. SCT website says it's a invalid S/N

Was the tuner "married" to another car?

I would re-install the tune back in that was in there before you loaded the stock tune. Is it possible the ecm is for the 2 valve engine?
