Really need to get a scanner on it and watch ICP desired and ICP actual. Might have some sort of a high pressure oil leak.

What kind of scanner will it take to see that. will like a matco scanner work or will it have to be done at a dealer

Matco would probably work. I use Autoenginuity with the Ford enhanced bundle, it's like a $350 software package.

You MIGHT even be able to do it with an SCT handheld too and a labtop with the livelink downloaded.

Of course, the dealer can do this as well. Where are you located?

ok i put the truck on a scanner and checked the icp actual and desired they were the same, but the scanner showed 3 things P0336 Crankshaft position sensor sensor performance; P0487 Egr throttle position control circuit; P2291 Icp to low on cranking. Would any of these things be causing my problem?

ICP too low for sure. The crankshaft position is typically thrown when you try cranking the truck a lot.

the code said icp low when starting this guy said that a sensor could be bad making it say that because they scanner said the actual and desired pressure were the same. so what do i need to do to fix that?

change the icp sensor, i think its on the passenger side valve cover on the 2004.5 and newer

what about that egr code is that somethin to worrk about

you can clean it, but mines deleted so i dont have to worry about any egr crap
