Check the linkage and friction-assembly first - as Allan in NE already mentioned.

If your injection pump is a rotary - then it is lubed internally with diesel fuel - but a shaft o-ring could still be swelled and binding.

If your injection pump is an in-line, e.g. a Simms or CAV, much of the internals rely on you checking the oil level once in awhile (motor oil). And, I've seen many run dry with the owner unaware - especially with some older British IH tractors and Fords. The in-line pumps are basically an oil-filled camshaft box with little separate injector pumps riding on the cam - one for each cylinder. When they get run dry, the cam followers get stuck - and sometimes the throttle linkage.
I will also add that many of the older in-lines use air-governors and have butterfly valves in the air-intake that can hang up. I have several British/Indian Internationals like that, e.g. the B-275s with CAV inlines and pneumatic governors.
