I know this has been talked about a 1000s times but I just want to clarify a couple things. The truck is a 2001 with a manual trans. Hot wired the pump and it started right up. Good possibility that the ecm is going to be my problem correct?

Do you have a security key fob? It's possible the truck is preventing start because the truck thinks its still locked.

 

Is there any other error codes? Might give clues to CCD network issues or power issues. The fuel pump relay if it fails will toss a P1689 code and the truck won't start but the VP44 will start if hot wired. 

 

ASD Relay issues? I know this rare but its possible the ASD relay is clicking or preventing start up. 

 

P0606 code? That is an ECM death code and most likely will not start. 

 

Wait To Start light coming on instantly? If the wait to start light doesn't come on the ECM is not booted up and the fuel pump relay will not energize the VP44 so the pump will not start either. This is another form of ECM failure typically around the RAM being bad. 

 

All hi or lo volt codes. Another type of failure of the ECM where the 5V signal fails and could prevent starting. But again there will be a long list of error codes.
