Help me diagnose

The a new ecm?

If it runs on either, you have a fuel problem. Pressure or air. Don't use the either to much, or you will be creating more issues. Recently my 2006 had the same symptoms - cranks, starts on either, sometimes runs for 2-5 seconds, no codes. Would run for 2 minutes when I primed the pump. Installed a FASS fuel system- problem gone. Some have found the bleeder valve (plastic) sucked air, some have found the filter support cracked. Good luck

That's not true at all. You could have all the fuel in the world but if the injector doesn't get the command to fire it never will.

Agreed, however I understood there was no codes that would indicate an injector failure

Well Ecm and wiring harness are both good. Got it connected to a good reader and it shows a security code. Some how the security system is cutting fuel.

Going back to this question. I noticed everytime the door was opened the security light would turn on. The key fob also would not unlock and lock doors. I tried the whole over riding the security light trick but had no luck.
