Colorado Springs Possible major break down.

[Keith Knight]

Having engine problems. Check engine light came on and code 164-2 Engine -PID injection control pressure data erratic intermittent or incorrect.
Wondering if any one is in the area I could park while I did the work. We are fully contained living, cooking, eating, toilet. Don’t need power or anything else just a safe place to work on it. We also have a motorcycle for going to get parts as needed.
I also have all the tools to work on it.
Any help would be greatly appreciated. My phone number is (863) 781-0165.

Most likely pressure sensor, solenoid, or the HUEI pump.

You need a HEUI pump. *maybe* injectors but in my experience with three of these I haven't run across a badly contaminated injector yet.

Get into CAT ET and go into the diagnostic tests and you can increase/decrease the HEUI actuation pressure. It will probably be jumping around at the lower pressure ranges and maybe more stable at higher pressures.

You can try the actuation pressure sensor and solenoid (3126 HEUI pump it's replaceable unlike the C7 which has the solenoid internal)..... but I have not seen one success with those on any of the trucks that I've been involved with that did this.

The two trucks where this happened on the road were able to get back home (~1500 to 1800 miles in both cases) by pulling over and unplugging either the solenoid or the sensor and power cycling the ECM with it unplugged and then plugging back in and restarting. This seems to cause the ECM to run some sort of diagnostic routine on the solenoid - I've speculated that it probably runs it through it's entire range to set a home position and that seems to "help" it run better for a while.

But yeah - your symptoms match all three of the trucks I've done HEUI pumps on - EXACTLY.

I'm praying for you buddy, can't do much else.

Stay safe

Prayers are welcomed! Thank you!

@jrtoffroad might have a suggestion

@MatthewWBailey might also.

 

[Keith Knight]

Thanks, Matt is way far from Colorado Springs.
Not sure where jrtoffroad is.

 

[Keith Knight]

I reached out to jrtoffroad with a private message. Hopefully he gets it.

 

[ckouba]

I think @B-Dog is in Denver?

 

[Keith Knight]

Thanks I’ve had a few people reach out from Denver area. So many kind people, I’m grateful for their hospitality. I’m just afraid to drive it that far. And having a total meltdown causing a wrecker service.

 

[marchplumber]

Nothing like what you got, but breakdowns on road make a person humble and magnifies the great assistance available here on S. Soldiers!! My prayers are with ya also.....if ever in Illinois, you are welcome HERE!

My last major breakdown while traveling was an o-ring failure on the high pressure side of the of the HEUI pump squirting oil out at a very fast rate. Luckily I was only 10 miles drone family in Michigan. Relatively easy repair thank you! It took longer to degrease the entire truck. Atomized dirty diesel oil is a blast to get off.
What doesn’t kill us makes us stronger. Blessed it happened when it did both times. A few days before I was 150 miles to the west of Colorado Springs where it’s extremely desolate.
I found a camp ground next to an event center for $20 a night. Remanufactured pump and o-rings will be in tomorrow afternoon. Install it Saturday and return the core on Monday if everything goes as planned.

Well at least it isn’t buried in the valley like on a PowerStroke

We lost our primer pump recently and now that we have it all back together it looks like the HUEI is gone. Only 283# at crank. Fortunately we are home now.

I was thinking about trying the solenoid, though with the potential for losing $1,000 injectors I am thinking whole manufactured if we find one. It would be nice to see the necessary parts list before tearing it all down—

 

[GeneralDisorder]

I tore a 3126 HEUI pump down.... Mind you I was legitimately a pump rebuild technician in one career path.... I could not find any smoking gun. I can say there is a surprisingly large amount of soft yellow metals in it and the whole thing is quite intricate and TINY inside. Pistons the size of the tip of your pinky.

IDK but none of them are going the distance. The failure rate seems to be VERY high before 50k miles.

At the moment, I'm 300miles from you. Keep us posted. I have a spare crate engine in the barn for this very reason but I only drive my truck in 150mile loops lol. If you can't find parts let me know

I'm a very new owner of an M1088A1 with a 3126. I'm just learning about HEUI pumps here and online, youtube, etc.

HEUI failures mentioned here on SS concern me.

What do you guys think about:
The NEW GEN 2 IFS Kit

If I understand it correctly, from this page:

It seems the kit filters the oil and protects the injectors from debris coming from the HEUI pump. It doesn't protect the HEUI, but limits damage downstream.

Is this worth doing for $1000?

When I get the Habitat built, I intend to take the truck to some far off places. Maybe a spare HEUI onboard?

 

[GeneralDisorder]

Personally I have seen zero benefits to the IFS kit. I've installed two of them and I'm no longer interested in one for my own truck. In the three cases I've done 3126 HEUI pumps the injectors were totally fine and I never saw any metal on any of them. Injectors worked fine and continue to do so.

To the "saving the injector" argument - that assumes they will get contaminated - haven't seen it. And it also silently assumes those injectors are *worth* saving and I don't believe that to really be the case either. I've seen enough of them have actuation solenoid failures and o-ring issues that if I have an injector failure there's just ZERO chance that I'm going to not replace them all. So time comes I have an injector issue I'm going to swap them all. And time comes I need a HEUI pump I'm not going to touch them.

The very narrow circumstance where I need a pump AND it went nuclear in such a rapid and unforseen fashion that my injectors are also trashed then I lose the gamble. Being I am VERY IN TUNE with my truck the chances of that occuring are extremely remote in my estimation as all the other failures I have dealt with were being piloted by folks that are probably not quite in tune with the machine as intimately as myself.

I also don't like the violent way they vibrate and saw through everything near them. And 4,000 psi running through vibrating hoses that saw through anything in their path including each other..... Yeah I'm good no thanks.

I installed the Gen 2 IFS kit this past fall as a preventative measure.
Mine started acting up 2 days before I got the check engine light and through a code.
Zero contamination in the IFS filter.
Installed the new HEUI pump today and cranked up on the second long crank. Ran rough for a few minutes working the air out. Running good now. Though I haven’t had a chance to test drive it yet.
I want to start another thread focusing on this HEUI pump subject. I have all the part numbers and costs and will post them soon.

 

[GeneralDisorder]

Yup. Exactly the same situation I've seen. The 3126 trucks just keep dong this. I'm sure you're going to turn in that pump for a core (don't blame ya) but I REALLY want to know what the hell is going wrong with them. The lack of understanding is killing me.
