Help, I posted a Moaning Noise thread yesterday with no replys, so I thought I would post this,

Yesterday afternoon, I was headed home, my truck was warm, I was on the interstate doing 55-60 into about a 20 mph wind, all of a sudden at about 2000rpm my truck surges forward like i just kicked in Nitro or something, it only did it for about 2 seconds. I figured it was just the wind stopping for a couple second. About 5 minutes later, it did it again. Thought same thing.

This morning, it did it again on the on ramp (no wind at all) and only a couple seconds. I get to my exit an stop, the motor is kinda running rough, like air in fuel. I revved it up a little and it quit. As I take off some idiot stops in the middle of the 2 lanes to turn the wrong direction, I speed around her and then spin out on some ice, nothing bad, just enough to get the tires to spin. It reved up pretty high (3000rpms), and when it came back down, was making a grinding, rattling noise. Like a bearing in an old wagon wheel. The motor surged about 5 good times within a 8 second time span, to the point I had to push in the clutch and let it roll till it quit. I took off again and the noise went away until I let up on the accelerator. About a 1/4 mile and it quit.

No noises, no surges til I get to work about another mile. I pull in the parking lot in my usual space and let it idle for about 2 minutes. The whole time it would spit and sputter then run as smooth as silk, then spit sputter, smooth out, etc.

What the heck is going on with this thing, I am sure the noise (grinding, rattling) and the motor surge have nothing to do with each other, just coincidence. But what could they be?

 

1990 F-350-cc 4x4 fake dually
7.3l ATS wastegate turbo 3" exhaust
5spd
DUH, figured ya'll might need this

 

hmmm, sounds kinda like how my f-350 at work started off, then it hit hard, full no idel un runnable, what about an injector pump, or injectors? or possibly just a plugged fuel filter, i would start with a filter then see what happens.

 

How many miles firemarshal?
How cold was it when this happened?

If it was below 25 you are far enough south the fuel may not be blended and you may be seeing the start of your fuel gelling. (Parrafin wax normally dissolved in your fuel is starting to solidify and stop up your fuel system)

If you have a lot of miles the grinding might be the governor getting ready to step out to lunch, a long lunch. (The one in the fuel pump)

 

I left work yesterday, got about 1 mile and it shuts off. I tried to start it, nothing, switched tanks thinking maybe the pick up tube broke (had almost 1/2 tank) and it starts but runs like crap. I get it about another mile trying to get to a gas station and it dies again, this time no start. I got it towed to my dad's place.

I went to check the filter, it didn't have much come out of the drain, so dad told me to give it a quick crank to see how much fuel would come out. Very little. my filter for some unkown reason has no separate water separator that goes onto the bottom, it is a complete sealed unit with a draincock on the bottom. Weird. We couldn't get it to start, nor could we find a replace ment filter that late at night. We kept the heater on in the shop so that this afternoon maybe if the filter or a fuel line was frozen that it would thaw.

It was about 20 degrees yesterday, and I doubt our fuel is pretreated for gelling.

The tow truck driver also said it may be water in the fuel, cause what I explained to him, he said , was the same thing that happened to his diesel tow truck. He said he had been getting fuel at the same place I do and that a week ago his did the same thing as mine. He said it turned out to be water in the fuel and it froze up his fuel lines.

I got 20k on a rebuild, it had a new injector pump, injectors at that time.

 

Try some fuel treatment, theres some stuff out there called power service, it will go up the fuel lines and help you out of a gelled situation.

 

I got it running. It was gelling of the fuel lines. When I asked the gas station about treating their fuel, they had no idea what I was talking about, this wasn't just a stupid clerk either, but the head manager.

 

Did the "head" manager seem to be wearing knee pads?? I think I would look for another place to get the fuel if 2 of you got the same problem. Seems to be a large sum of water in the storage tank ... whatcha think??

 

Yeah, it seems like a large corporation with a fueling station in the middle of a rather large industrial park would care about diesel with all the big rigs and dump trucks and so forth running around there. I guess it goes to show that a profit means more than a customer.

As for the knee pads, probably so! LOL

 

Personally i dont rely on fuel stations,i always add a little additive at every fill,even in the summer.These ip's need the lubricity all year round.
