That's a good one as a practical example, that said (in this case) I'm not sure that a screen could hold up to 3000 + psi differential!! I suppose if the plug were solid enough it could!

With those numbers, I'm in the camp of "something is wrong" as well!

I think he is aware of the symptoms and the data. Question is - what are YOUR plans?

You have been given a couple of directions to explore. We aren't able to identify the specific issue unless we get lucky with a guess. You, on the other hand can do some testing and inspection.

KOEO?? Just what I expected...something's wrong alright LOL

UNFORTUNATELY, your ICP sensor is kind of a pain because it's behind the turbo on the HPOP with your IPR. FORTUNATELY, that is where you're headed anyway, so...

If I were you, I'd pull the necessary crap out of the way to get to the IPR & ICP. First, disconnect the ICP sensor and see what the above PIDs read KOEO (ICP, ICPDes, and ICPv should all be 0). If they are, try to start the truck. If it starts, i'd replace the ICP sensor and pigtail. If it DOESN'T start or the above values AREN'T 0, you might have to change the ICP pigtail anyway to get there first. However, I would also pull & inspect the IPR (you're gonna need a special socket). Suspecting a short in the ICP sensor or pigtail like @bismic mentioned earlier (03 & 04's are known for this).

Another thread as a good reminder to have a known good IPR on hand for troubleshooting...

Well, I'm going with option one...Electrical short...Squirrels is my guess...

I swear I've been driving it every week or two...

They chewed up the wire loom and some of the sheathing around the power wire.

Then I noticed one of the little ****s made their way back here. This is where the harness branches off to the ICP sensor...

This is why the ICP sensor volt request was made so early in the thread!

Anyone know what harness that is and possibly what the part number is? I have a friend that works for a Ford service center. He might be able to get me the harness so I can just replace the whole thing and not worry about any other possible breaks in the wires.

That is part of your main engine harness.

You will be better off making 2-3 or 3-4 wire repairs.

Wait a tick - you're JUST NOW lifting your hood to reveal this???????

From the book of Dude Rules: Chapter 1, Verse 1 - "Wheneth the truck won't starteth, lift up thine hood and stareth towards the engine bay from whence sits thine engine. Acteth like thee knoweth wherein the problem lieth!"

C'MON MAAAAN!!

I'm out...

LOL, Jokester. I was thinking the same thing - dude hasn't even got out of the driver's seat yet. But what about that black degas bottle? Wonder what his deltas look like.

It's not black... Entirely. It's original equipment. The top is black but the bottom is just old and dingy.

When the bottom is that black, there's often oil or soot in the coolant. Sign of possible blown oil/EGR cooler or head gaskets/rings.. even if not, I'd clean it up or replace it just to be able to tell if your coolant is getting dirty.

You can't get it completely clean, but it's easy to take off, then rinse with a degreaser.

but maybe you can see into now. Just doesn't look clear enough in that pic.
