Hm. That's a good thing I suppose. Only negative is still on the hunt for the problem... I checked DTCs as well, initially I had a ton but I also had a plethora of issues with various modules that I have fixed since purchasing the truck. After clearing and re-checking, I only had four (U1262 - FORScan says to disregard; B1352 - not concerned its regarding key dinging; P1000 - PCM not ready, expected; P1876 - 4wd solenoid and I don't use 4x4 very often at all, can delay until later).

Like cleatus12r said, this data looks normal to me. Did it stall on you or have any other issue we can look for? If not, keep logging with each drive, and when the issue happens again, save that file and we'll take a look.

Yep. The very end was when it died. Just an estimate on the lines here but I left a stop sign right in front of my house around row 79500 and then at 79778 it died all on its own. I was in drive and accelerating. Put in neutral, coasted to my house, parked, and pressed stop on data.

Ok, here is the section from stop sign to stall. Looks like ICP drops, and MFDES asks for more and FUELPW increases, but RPM keeps dropping.




Did it start again?

Negative. Once it stalls, it only cranks until it cools for a few hours.

Is the ICP sensor original? Unplug the pigtail and see if there is oil in the connection. See if it will start with the ICP unplugged.

I am unsure if it is original. It looks like it has been there for a while. I disconnected it the other day and there was oil inside of it. The truck is cool now so I will have to delay the invocation of no-start until tomorrow.

Ok, that ICP is suspect, given the connector oil, and your symptoms. Recommend unplugging it, and driving with ICP unplugged. The PCM will use a default values for ICP. If the rig does not stall, the ICP sensor is likely the culprit.

We recommend replacing it with a motorcraft part from a reputable seller, due to fakes out there. With that oil leak, I'd say get one on the way and eliminate that variable. Riffraff diesel performance and Dieselorings are good sources.

My phone really did not want to take good photos with no lights outside so this was the best I could get tonight. As you can see, there is oil on the rubber part and also pretty much the entire part beyond the rubber. I can do the test tomorrow to see if that improves the situation by disconnecting it.

That's a great pic - if that's not the problem, it's certainly headed that way.

Please get a log of data WHILE CRANKING after it stalls. I want to see what the pressure is when it doesn't start.

Unless there’s some sampling delay or such, it appears the rpm starts to drop before ICP falls. Could this be as simple as a failing CPS?

I will gather the no-start data today too.

I sure hope the CPS is not failing. I have replaced it twice. Once with aftermarket and one with Ford.

CPS failing no big deal.
I've had Motorcraft CPS failing after 6 months.
Always keep new in glovebox.
