injector pump?
I have also noticed the lift pump isnt kicking in when I bump the starter. I bumped the key on 3 times to see if it would give me any codes and it says NO BUS. Do you still think its the injector pump?

I ran the pump stand alone and the truck runs. Now I'm leaning toward the ECM or PCM? What do you think

You could pin out and verify the pump is getting required voltages, I've posted the connector pin out somewhere.
You could standalone the pump and see if the truck runs. Otherwise if no the vp has power the pump is done. Hate it for ya man.

Which code for no bus. Ecm would be the next inline for failure
I almost want to say that the pump may allow it run without communication in a standalone but don't hold me too it. Basically what im saying is while no communications could prevent it from running while hooked to the truck electronics but the standalone would still allow it to start. That's a pretty unlikely option but its something to keep in mind
