I would post in the 7.3 forum. You will probably get better help.

You'll find everything here from engineers that actually designed Ford components, to trolls. The trolls aren't hard to spot because they leave a lot of droppings.

If I'm not mistaken, the IDM is nothing more than an amplifier for the PCM signals to the injectors - a little like a fancy-schmancy GPR. I doubt that needs to be programmed. Look at the last link in my signature and that will help you to cover the many known quirks on the PowerStroke version of the T444E.

Ah hell... click all my links, there's some good stuff to know. You are a perfect candidate for AutoEnginuity! I have trinkets on file (too big to attach here), PM me if you want me to send them.

Again... welcome to FTE!

I'm sure ou already checked battery voltage and TNT the glo plugs are working. Mi had a no start issue once cause I didn't have my truck plugged in and glow plugs weren't working. My buddies wouldn't start because voltage was below 10.5 while cranking.
