I HAVE NO NO NO 12V TO THE INJECTORS

You do or do not have 12V+ at the fuel rail? Ign on there should be steady 12V+. Running there is a neg pulse sent from the ECM. No power is fuse or bad connection. Fuse boxes are a known issue on these rams if they get weather in them. Jump a fused hotwire to the injectors to determine if the neg pulse is good.

Neg pulse signal is determined by cam sensor. Cam sensor is on the passengers head, front lower side. Tone ring can be damaged that it reads. Can pull the valve cover to inspect.
