Regarding my tractor's possible issues with the injection pump!

I had an older Ford that acted the same way when starting on 12v. In my case the shutoff lever wasn’t returning fully and it restricted the fuel a lot. Since you said yours doesn’t reset all the way, the mechanism inside the pump might be sticking. I cleaned and lubricated the lever assembly and it made a huge difference.

Good advice, I hope Arber sees it!!

I still have to get my 2000 working but similar issues, I know for a fact the pump is just gummed up, been through it once now but must have broken something else loose...

Reseal kits are only like $15 for these pumps, not super hard to deal with. I took the starter off and just dealt with the business end of the pump in the back (after taking the top off of course).

There's a check valve and screen in the fuel inlet to the vane pump which could be suspect on yours.

Refurbished pumps aren't super expensive, but yeah, I don't want to do that yet either...

Hi, everyone I am new here and have been having some issues with my Ford 3000 tractor.
Here goes>
The tractor refuses to start at 12v and basically cranks forever(there is no smoke while cranking or even an attempt to start) however at 24v(two 100AH batteries in series or 24v) it starts right up! Yet it doesn't smoke even when it first starts or when pulling things or even when punching the gas... it simply never smokes!
Now I have rebuilt the starter at a local starter machine shop thinking that is the issue but nothing really changed really it cranks the same like some videos I have watched on youtube so there is no problem there also compression should not be an issue since it works very well and pulls great once started and running but still doesn't smoke, it has a down exhaust pipe and the pipe is in good condition and not clogged.
My current suspicion is the injection pump which is a Lucas CAV DPA pump and it does have an issue where if you run it out of diesel bleeding it is a literal nightmare which does point out to the pump or rather the vane pump!
It has all new fuel filters as well as clean everything lines tank everything is spotless. Is there hope that I can fix the problem myself or just get the pump rebuilt and stop pulling my hair or could the problem be elsewhere!
Previously I have owned various Massey Fergusson tractors and none have had this problem!
Any suggestion feel free!

Edit: The shutoff lever doesn't reset fully after shutting off which is another clue to the problem being with the injection pump!

I would do a compression test on it.and have you tried starting fluid while on 12 12 volts?

Plungers are sticking inside the injection pump. Needs rebuilt by someone experienced.

Remove an injector using the fuel line hook up injector so you can see the spray pattern.

DO NOT put any part or your body in front of the injector, it can "inject" diesel fuel into you body resulting in blood poisoning.

Crank tractor and observe the spray from the injector, if any. My thoughts the head (the distributor part) is worn and leaking too much. Indicated by a faster cranking speed it starts.
If the compression was too low you would have excessive blow by, or oil usage. You did not state any of this.
Being it is an older tractor and probably has not had the pump or injectors serviced suggest you at least have the pump tested (a prove me wrong?) and have the injector cleaned and set.
