My PS is one sick pup. I have been reading a lot of the posts with trucks that are having the same problems as mine but there never seems to be a definite answer as to what fixed the problem. okay here are the symptoms that I am experiencing....

Hard Start: In the mornings, it will start, die, then restart with a nasty "loping" (basically feels like only half my motor is operating)

Once operating temp is reached, it seems to run smoother but once driven there is horrible power loss. It feels like I am driving into hurricane force winds or towing something ridiculously heavy. It has even died at times while driving.

To date, and have replaced my glow plugs, my CPS with the new version (-B), and replaced my UVC harnesses (both sides). I am now leaning towards the IPR or IPC. With the choking and sputtering I am also thinking about the EBPV and associated sensor. I do not have a check engine light so I am assuming that there are no codes to be pulled. Any help or advice would be greatly appreciated.

I 'll assume the oil is fresh & full...

Here.... Is some reading for you...Scroll down to #5 & see if anything sounds familiar

 

[JasonShort]

hmmm....The oil is good, but I dont recall getting an immediate response from my oil pressure gage.

 

[action4478]

You age going to have to verify sufficient fuel pressure , & hook up a mechanical guage or a scanner to verify the high pressure oil system cold & warm...Read... This....

 

[JasonShort]

Do you have any pictures associated with this...or know where I can find some?

 

[action4478]

I'll see what I can do...

On Edit ...Idont have pictures,, I wish I did ,,

Maybe someone else will for both of us...

I found this ... Click here... Once it is opened , click on the drawing to enlarge it....

 

[JasonShort]

Great information, but it just seems to be a little in depth. Not that I am lazy or anything, I am just a little unsure and I dont want to bite off more than I can chew.

 

[action4478]

Might you have a friend that can help you with it ?....

 

[JasonShort]

Yes but with conflicting schedules who knows when we would be able to do it. I am trying to get this thing back on the road ASAP. It's my daily driver.

In the mean time, is there anything else you recommend looking at outside of what I have already done?

 

[action4478]

Change the oil , Maybe a 5 w ,Replace the fuel filter if you haven't already. Unplug the EBPV or wire it open, Empty the fuel bowl & fill it with sea foam, & use Stanadine fuel additive in the tank , about all I can think of....

 

[JasonShort]

Probably a newb question but...where's the fuel bowl? haha

 

[action4478]

On top of the motor under the cover ..The top is round ,takes a large screwdriver or equivelent, tp remove the top, it unscrews.Lay the screwdriver in the grooves...Look Here..

 

[JasonShort]

Oh duh....where the fuel filter sits...got it. ook with the EBPV, as read above I have considered that, how do you go about wiring it open?

 

[action4478]

On the bottom of the valve under the turbo, mine has a pie shaped (or so ) lever, connected to the actuator, looking down from the top ,full open is clockwise. (PO) wired mine open, now I believe it is rusted in place open...Have someone start the motor when its warm & watch the lever move, It may be just fine ,or stuck closed.... Look here...

 

[JasonShort]

Thanks....I'll update if anything new arrises and i'll be sure to inform everyone else on the forum as to what the final fix was.

[action4478]

Super...Good luck....( I see you have been reading)....

 

[JasonShort]

Okay...after many firm hits to the head and a few "adult" beverages I traced down all the lines and connections to my HPOP. On the intake side I found a loose connection which is what I am hoping was causing my pump to be below the level of oil recommended. So I tightned that fitting, topped off my HPOP, and cleaned the fuel bowl with some SeaFoam and she started STROKIN the way it always had in the past. I am going to keel an eye on that line and possibly later down the road replace it, but for right now it seems fine.

Thanks to Rick and all the other professionals on here that help keep those ridiculous parts and labor costs down.

You're welcome ,Glad we could help....

First post here... hello everyone. Wow, I am having the same issues as Beefle so perfect timing for such great responses. Hard start cold start only in the morning. Loping before a smooth idle. Fresh oil, new fuel filter, recently drained and cleaned reservoir/bowl. I think I'm about to follow down the same path here, but I've got a couple newb questions for these acronyms used. Can you guys please clarify what HPOP, IPR, IPC, and UVC harness? Sorry to ask you to spell it out, but the only abbreviations I know in the post is the CPS and EBPV.

Thanks in advance.
