3000 not running right help

[Larry in GA.]

I was over helping a friend of mine yesterday do some tractor work. He fell off the roof of his new poll barn last Nov. brook his neck and back and crushed his right arm and still doesn't have much use of the right arm because of nerve damage.
He has a 3000 diesel It will start right up and runs good at idle once you open it up it goes to sputtering sounding all most like an old John Deere. Diesels are out of my league Maybe some day I will give up on old iron and own one. Any help would be most appreciated.

first choice would be starving for fuel....

open line going into the fuel pump.. fuel should flow out.. if there is stopped up filter or something in the tank that blocks the flow of fuel this will happen... could be bad fuel pump.. or bad injector pump as the next two choices..

Thanks
If the fuel flow is ok do we check the fuel pump jest like I would a gas one on my truck?
There is something to be said for old gas tractors no fuel pump or injectors.
using his tractor is the easiest It is a little to far to load up the super C each time he needs something done. I will check the flow Saturday when I go back over there and post back.
Thanks again
Larry

I'd just change the filter first as a matter of practice, and if that didn't help I'd start looking for other restrictions in the fuel lines or tank. That tractor probably has a Simms pump, so if it does... then it's got a round lift pump on the outside of the injection pump. IT could be weak, but I doubt you'd notice a whole lot of difference if it were bad on that tractor.
Check the filters and flow first.

Larry, I'm pretty sure the injector pump timing is retarded. If it is a CAV pump, it has an advance built into the pump: the advance could be stuck. If you will advance the time by loosening the three retaining bolts/nuts and rotate the pump it should make a big difference.
On the other hand, if it is a Simms pump, it has no internal advance mechanism. You have to pull the cover off just in front of the pump, loosen the 3 bolts that hold the gear on the pump and rotate the pump drive in the slots in the gear. If it's a Simms, the bearings are probably bad which lets the pump of time. On a Simms you should change the oil in the pump every time you change your engine oil.

I'd check the fuel filter and air filtration system first before doing anything else.

My 3000 is a bit the same. This tends to happen after a long period of inactivity. If you try driving it, it will stall and be very hard to start.
I have never been able to find out what is causing it, but have discovered that if the cold start button on the pump is pressed it starts right up again. After managing to keep it driving this way for 5 mins and keeping the revs up it seems to clear itself and run normally. I suspect that it is drawing in air somewhere when it sits for a long period but i have never managed to prove this.
I replaced all the components from the tap on the tank up to the injector pump, and including the filter head, as the bleed screw is famous for stripping threads and drawing in air, but to no avail.
Another possibility i suppose could be a sticking piston in the injector pump.
Wish i could be of more help.

Do not know if this is relevant. I have an International truck with a Ford diesel. The truck was very hard to crank. Put an electric fuel pump on about a year ago. Changed the filters also. Have never had another problem. It cranks within 20 seconds every time reguardless of temperature.

If it has a Simm's pump on the side you will see a small round cap with a nut on top.Take this off and there is a wire mesh filter in it.Wash it out good with carb cleaner or gas.This may not be the problem but it can't hurt to check.
