The governor ring in the injector pump is a common failure. You can try removing the return line check valve and see if it has metal shavings in the valve. If there is, clean them out put it back together and see if it starts. It may if the valve is clogged.

Early system and not much info on the line.

Injector pump is real common on these old units. Governor rings were failing on the old stanadyne pumps left and right.
