We call them "stickies" (some forum sites actually use that term), but here on FTE, they're marked "Read First" in Red. They're the first four or five threads at the top of the section. I THINK the one you're looking for is this one - https://www.ford-trucks.com/forums/1...ostic-faq.html .
Correct, IDM is the MODULE (it's not really a computer like the PCM) on the inner fender, driver's side. Thanks to its ingenious (NOT) location, rain water coming through the hood/fender seam has been known to collect INSIDE the module. Pull it, shake it, listen for water. But the codes are sounding more like it's an injection pressure issue.

Don't sweat a KAM error. KAM means Keep Alive Memory. It's the "volatile" memory in the PCM that depends on constant power to be maintained. Whenever you disconnect the batteries, pull the constant PCM power fuse, or disconnect the PCM, that memory gets lost, and next time the PCM gets power it sets that code.
What was the exact code for the ICP?

the guy that had the scanner was not real knowledgeable about it but there was something there that said some pressure was about 270 lbs. on one of the scans,didnt know if it was oil or fuel.did a injector scan to the buss test and it said ok.

Fuel delivery is completely mechanical; PCM does not monitor or control it. So that 270 PSI would be hydraulic oil injection pressure. And it would be too low to run the truck. IIRC, minimum is 500 psi.
