Tucker doesnt want to keep running

We have a problem at Challenge Mountain with our Tucker. I think its a 200a. It's an inline six turbo diesel. It quit twice today. The first time we kind of figured it ran out of fuel, as the maintenance man only put in ten gallons in. We purged the line and it eventually fired, we checked the tank and it was half full, it's a 90 gallon tank. Thought maybe the fuel pick up was askew, so filled it up. It finished up the hill, but it felt under powered. I started on our sledding hill and it died again. I figure the pickup tube is bad, but it is welded in, ?? It must not be stock.
I can't post pics for some reason, but if someone wants to see the tank I can put it on our facebook page.

Also there is a plug in connector off of the alternator that looks screwed up, it has a black wire on one side and a white one on the other.

I cant post pics, must be too big, ill put them on our FB page, if you care to look, thanks.
 
does it have a lift pump? if there is not consistent feed to the injection pump the fuel can cavitate and will not run. i am no diesel expert by any stretch of the imagination. look for your fuel supply like you have done with the pickup. check the filters, drain water separator, check if there is consistent fuel being delivered to the injection pump.

i had fits with a new machine a few years back. it had water in the fuel, after draining and refilling the tank a few times, i finally found the hole in the tank that was letting water in. it would run but poorly and eventually it would die.
 
what year do you have i'm guessing a b series cummins so what pump do you have if it's a ve or p7100 check out the hose between the lift pump and tank i've seen the inside og the hoses seperate and collaps and block off the fuel supply i've also seen the hoses and fittings leak air and cause problems lastly if you have the same fuel heater the newer dodges have they are prone to having leaks i just bypass the fuel heater which is located next to the fuel filter and looks like a ufo with sone wires comming out of it
 
Its a 94. the lift pump must be the thing that looks like a primer. Thanks, I'll start there. I'm not a diesel mechanic, I race cars, so this should be a piece of cake. :whistling:
 
yes the lift pump has a primer attached to it get me some pics of the drivers side of the engine from the vintage im going to guess its a p 7100 injection pump but start your inspection process at the lift pump and go backward check the line between the lift pump and the filter than chect between the filter and fuel heater if equiped also some early model heaters were sandwiched between the filter and filter mount than inspect the large line to the tank remove the return line at the tank make certain the fuel is returning if you have a plugged return you can't properly fill the inejectors and fuel pump
 
Filters??you said something about maintenance and fuel,did that just service it? Filters the right ones,are they tight?
 
I've had the same thing happen the other day on my Pisten Bully and the fuel line has a small amount of ice clogging a 90 degree fitting where it came out of the tank. Cleaned it out and away I went.
 
We've got a busy day today, 50 visually impaired skiiers . I'll try to get to it this afternoon. thanks But it is a 359 5.9 lt
 
We got it running and down to the barn. It was like it ran out of fuel. There is a small inline filter that wasn't changed, all the others were changed and tight. The program director says he's going to call in a pro to look at it, if not I'm heading up Wednesday to fix it. I'm wondering if all of the ice on top of the tank could be part of the problem,maybe it's putting pressure on the lines. Can anyone tell me what that plug-in is on the harness coming from the alternator, it just doesn't look right to me, it looks like a broken fuse.
Thanks for the input, I'm sure it'll be running soon, not so sure if we'll get to groom again, but at least it will be running.
In the meantime, I am welding myself into this recliner and catching up on some relaxation.

I have one of these engines in an AG sprayer. In my case there was a generic inline fuel filter hiding between the engine and it's fuel tank. Don't know if Cummins put it there or some else. Untill we found it we had problems. Cheap fix, but no so with regards to time. Didn't know that little filter was there....Might be worth a check...

you have he ve series pump like the early dodge trucks its an afordable pump with a good rep so im guessing that the fuel filters are on the positive pressure side of the lift pump like a dodge which should rule out an airleak at the filter the diaphram lift pumps like the ve uses were prone to failure i have replaced 2 in my 89 also i would look for air leakace around the little filter you described and if the fuel tank wont vent your not going to get fuel
 
We had a couple of diesel mechanics come in and check it out. I guess they had an tough time figuring it out. I think we should have left it up on the hill and they may have had an easier time narrowing down the problem.
They say that little inline filter may have been a few microns off and a little plugged. I think that the filter was probably for a lawnmower and there was a restriction on one of the fuel lines. All that ice can't be good.
Now we need snow, if any of the snow gods are listening, so we can run it.
Thanks again for the input, I'm just a volunteer here, so i'll take all the help I can get.
