That would eliminate the icp sensor it's self as being the problem. If it's starts with it unplugged then you need to replace the icp and pigtail.

 

So, if the V is low, I have an oil pressure issue and if the V is high(over .8 to 1.15), the issue is somewhere else, correct?

 

Mostly that is true. That is why you ALSO try starting after disconnecting the ICP. That test should rule out a bad ICP sensor.

 

Well, the ICP is fine then, no chaffing on that harness. I am making the 6hr trip home now for a week of training that I have to do. I hope to get back up as soon as I can with a scangaugeII and get this thing fixed. I hope it's something easy and cheap, but I'm not counting on it especially with my luck as of late.

 

Goodluck with your truck! keep us posted

 

This is going to be a long week while I sit here and fester knowing I can't do a thing about it.

 

I found the OASIS report on my truck and found quite a few interesting things.


At 35K miles:
the cold side CAC tube was replaced, all 8 injectors replaced due to sticktion.

At 70K:
EGR cleaned

At 90K:
installed stc bracket and or replaced stc fittings, EGR replaced due to failure.

At 100K:
replaced injector harness and injectors 3, 4, 6. Replaced EGR cooler and oil cooler. Found code P2291 - repair and replaced IPR and HPOP.

That's all I got...nothing on there since and the truck has 204K on it.

Any thoughts?

 

Check plugs going into FICM make sure they are snapped into place. Happened to me during diagnostics.

I am in GR and have a flatbed trailer. where is your cabin? I would be willing to help when i get back in town on Thursday night. you get the beverages for the corner and we can do a road trip.

 

with all those injector Failures you need to check the fuel pressure or atleast put the blue fuel pressure spring in

 

Is this the correct part number:

Ford 3C3Z-9T517-AG

 

Seems like you got someone whos more than willing to give you a helping hand?

 

The cabin is on Drummond Island...the E end of the UP. It's about an hour drive after the bridge. I will definitely take your offer into consideration, thank you!!!!

 

Yes and some IH alternatives:

Fuel pressure regulator kit 3C3Z-9T517-AG 1843065C98 or 1854267c94 (no cover)

 

I'm gathering a list of possible fixes and considering taking with me:

OEM oil filter and cap
OEM fuel filters and caps
blue spring update

still thinking about:
STC fitting
dummy plugs
stand pipes

If I take the HPOP parts, I am also considering an EGR delete kit while I'm in there.
