Dying Diesel
Hey,
I have a 1986 6.9 and today when I was driving it down the road it just died. I tried to restart it but nothing happened. A few minutes later I tried it and after pumping the gas it restarted. I ran it for a few minutes and turned it off. A little later drove it again and it died again, twice. the second time I never got it restarted. What could it be? Last night it got down to 12 degrees, does that matter, I never put any anti-gel in it. Or is it the pump or relay, etc. Please help, it is sitting in a gas station as we speak. Thanks

MUDN69,
You might just have found out why they make an anti-gel for the fuel.
Where've you been getting your fuel? Might have gotten enough water in the lines, or even the tank, to freeze and block fuel flow to the lift pump.
Have you attempted to drain the filter to see if anything, water or diesel, comes out?
Have you checked the obvious stuff like tees leaking or any of the tubing with cracks around the edges? R.A.

sounds like the same thing that happened to me driving my truck up from Oregon to Alberta in February. hit -40 celcius and the fuel gelled up & the truck quit. i'd been putting additive in, but it wasnt enough for the weather. let it sit for a few minutes and the engine heat had thawed enough fuel to start it and drive again. found an old deisel mechanic who had us put 2 liters of kerosene into each tank (dual 19 gallon). never had a problem since. they put fuel anti-freeze in at the pump here, so it's not such a worry.

Well, it may be gelling in the fuel, and tomorrow i am going to check it, all my fuel is coming from local gas stations. It has been about a week or two since I last filled up. If i put 2 gal of kerosene per 19 gal diesel, will it automatically start to break it down or will I need to run it around a bit. Also could it be a relay or fuel pump, anything else?

It will break down what is in the tank....but what is in the lines will be another story. Your filter is probably plugged and the lines as well. A warm place for a few hours is the easiest way to get it going again.
Highland County is west of Stanton on 250 about 40 miles. The reason I asked is some of the pics in your gallery look like that area.

I gelled up last year. even though I used antigel and diesel #1. I towed my truck home put it in the garage and put some melt down in the tanks and I changed the fuel filter. It started up like a champ the next day I had the garage up to 95 degrees all night long thank god for wood burners.

I just purchased a F250 diesel, and I'd like to know how to know what kind of diesel I'm putting in it. I have nada knowledge about diesels, it's my first vehicle. I buy my fuel at Sunoco, or at a nearby truck stop. What kinds of diesel are there, I see stuff about number 1 2 and 3 diesel on these forums, and I have no idea what I am using. The temps get below 0 at night here right now, so I guess it could be a problem.

you may well have an air leak on the suction side of the pump. If the pump can pull air instead of diesel fuel it will. Pumping the gas on a Diesel is just good exercise for your foot. the fuel pump automatically goes to max fuel when you crank the engine and stays that way until the engine fires.

Hmmmmm...... I don't necessarily believe that to be true. If it were to do that it would have a tendancy to over rev at start up. Also if I am sitting there trying to start it and have no luck but then pump the gas and start it like I did, I have to say pumping the gas gave it more fuel-oil.

Trust me in this, I have been a Diesel mechanic for the las forty two years. All the fuel pumps I am familiar with except a C.A,V. pump with hydraulic governore go to full fuel on start up. The minute the engine fires the governor cuts the speed back to what ever the spring tension on the governor says. This spring tention is set by where you place the throttle.

I believe mechanic is right- there is no "accelerator pump" to squirt fuel like a gas carbureator has- nothing like that in a diesel pump- so pumping the foot feed is only opening and closing the governor- if the motor is not running this won't do a damn thing but exercise your foot
