This is a vid oft truck starting in 35deg. I'm hoping someone can just tell what's wrong!

Looks and sounds like the romps... What type of oil are you using?

 

I agree. Sounds like romps. When you say you don't drive it in winter, how rarely do you mean? And I'm also curious what kind of oil you're using?

 

HPOP? or IPR??? maybe? just guessing....

Any codes that you know of?


Edit:
Is your power or mileage down?

 

Try letting the GP's stay on longer? Seems like you're just waiting on the wts light to go out. Sounds alot like a miss at the exhaust too, might be injectors not firing cold.

 

Yep -- romps..... Here's mine blowing a cloud in the 20s. No audio though -- it's from a cam mounted up high. I can get one with audio tomorrow morning. It'll be like 8 deg....

 

mine did that when my gpr died, might be 1 thing to check.

 

Sounds like a classic case of the romps. I would change your oil to 5-40 synthetic and I bet it will start right up with no trouble. Mine sounded just like that till I switched over to 5-40. This weekend it was -5 and it started fine with no romps.

 

Synthetic oil would definitely cure the"romps",but I don't think the romps would keep shutting it off like that.Has the cps been changed?,I think there is something else going on...

 

15/40 rotella and it only romps the first crank. It's got a new ipr and I've been thinking it's got a weak hpop but I fixed that problem today and got a spr1 hpop from beans diesel today. It should be here by the weekend! If my glow plugs weren't working wouldn't there be some smoke. Same thing for the gpr. The only time it smokes is when it first blows out that unburnt fuel from the attempted starts. And for the synthetic fix I haven't had any issues like this with any of the powerstrokes we have at work. We have 8 total and mine is the only one that romps. I guess I figured 30's weren't cold enough for the syn.

 

Black cps less than 6 months old.

 

Synthetic "cure" to some is a band aid to a problem, it will take care of it, but is also covering something else in my opinion. a couple years ago mine started romping like that and as soon as i switched to syn, they were gone that winter, but the next year, my injectors were in need of replacing, after replacing them since it was in the summer I put dino in, and haven't had the romps at all, not plugged in and its 5 degrees this morning. Just my experience of course, that's why I see some validity to the ICP.

 

Makes no sense how the oil could be the problem... it's been 20's and colder here and I run regular ol' 15W dino oil. My truck did have a bit of that when the glow plugs were bad, but the truck wouldn't fire at all... it'd just spin and wouldn't catch. Also, he's not making ANYWHERE near enough smoke to be the glow plugs. Mine had 0 glow-plugs and I couldn't hardly get the truck to catch in temperatures much colder than 60. His catches just fine.

OP, I'm really thinking you have an oil issue... you said you have a new IPR so that's pretty much not the problem. I'd say O-rings or HPOP... don't see how the HPOP or sticks could be bad since both have barely 120K on them (or whatever you said they had... somewhere around there). Wonder if your ICP jumps when it does that? Need AE or a gauge to watch that when it's cold...

 

bulla, since we are in the same neck o the woods and experience the same temps, mine does have a case of the romps in the winter from time to time. It usually does it in temps below 40 if i wait for the wts light to go out and then start like in your video (but not to that extent, only died on me back to back like that once, ever. usually just sounds like dammit til it straightens out). I havent rigged up a gpr indicator light yet but what i started doing was after the wts light goes out I count to 10 and then crank. It usually cranks up with no issues. Since i started doing that this year there was only one time ive had to cycle it twice to start and that was a few weeks ago when it got to 24. Suppose to be lower 20's in the morning so ill put theory to test again. I changed my oil last week (15w40 Rotella) and put in Delvac this go round. The new oil may help out a bit, I also added one of the "snake oil" additives that are suppose to help with the romps. Since Ive done this, no problems, but again the low temps in the morning and next few days should prove out or not.

 

I believe the low oil temps are causing the romps (because there is some other issue) and as everyone knows, dino 15w40 gets very thick in the cold, unlike the syn oil, which is why the romping goes away when people switch to synthetic oil. They didn't cure the problem, they treated the symptom. IMO. (this is applying the temps the OP is starting in, I know if it is real cold the syn oil is a huge improvement)
