Well, just like the title says, the engine started to cut out this afternoon. Here's the scene: Engine was fully warm. Outside temp around 15*. Pulling a pretty good hill that I usually do in 5th@60. I had it in 4th, figured I'd wind her right to the gov, just for the heck of it While maintaining 65 in 4th and about 20psi, the engine began to break up. EGT's were running 700-ish post turbo. I let off and shifted into 5th and gave a tentative stab of the throttle and it was firing on all 6. Proceeded the rest of the way home with no problems, but I didn't wind her up again. Had about 1/2 tank of fuel and I'm running a full dose of Power Service in the white bottle with this tank. Thoughts?

Just what happened to me, I'm not saying this is what is going on with yours.
I had my engine cut out briefly pulling a hill in OD, turned out to be broken plunger return springs in the pump.

 

Huh....that doesn't sound cheap.

 

Haven't you been having fuel supply line "issues"? If it sucks air it will cut out - just ask Vinny. You might want to put a fuel pressure gauge on it so when it does it again you'll know if that was the problem.

No way that it's a gelling problem. At 15 degrees the PS white bottle would keep things flowing even if the fuel heater was dead.

 

Thanks Dave. Maybe I should pick up a pressure gauge this week, since that's the great unknown in this equation. I spliced rubber line on the supply side and that cured my slightly-slow start this summer, but haven't checked up on my zip-ties...maybe I've got one scraping through...I'll check that tomorrow.

 

BTW, I asked the parts store for 'diesel rated' line. Is there any way I could have gotten the wrong stuff, and if so, what are the symptoms?

The hose will get gooey, and eventually it will break down and clog up the filter.

 

are you saying you used zip ties to hold your fuel lines on or you mean you used zip ties to hold them up on the frame rail?

 

Just the frame rail, hehe. But, they were little ones, so they could have cut through, theoretically.

 

oh ok, hope you get your problem figured out good luck

 

Got some 'diesel rated' fuel line this morning and replaced what I had. The old line felt real spongy...the guy at the parts store said it's all the same stuff...I made him look up a diesel application in the Gates book. It was the same stuff that he sells for gassers, so maybe I just had old crappy line. Got a new fuel filter, just for good measure. It felt great throwing away a 1 week old Baldwin$$ filter....She runs good now, though, so it was worth the cost. It was -10 with the wind while putting the line on...I don't know who liked it less, me or the truck:

 

good to hear shes running better for you now. I wish mine only smoked that much on start up

 

Wind chill doesn't count

Glad you got everything fixed.

 

''Wind chill doesn't count''

Haha, Alec! I was plugged in, so I was already cheating...

 

If your problem persists, especially if the engine seems to shut off when you really lay into it and comes back on like a switch after you let off, look at the ESS pump solenoid connection. Mine had a connetion problem there when I first bought it. After serious diagnosis with a multimeter, I ended up putting a new female connector on the wire and polishing the male contacts, problem solved.
