What did you do to make that side of the pump operate? Sometimes a gentle tapping with a hammer or mallet can loosen up a frozen plunger. Are you absolutely certain there is no air in the system to the injection pump?
Until you have flow coming from both lines, don't worry about where they go just yet. I don't know about the Mitsubishi engines, but Yanmar numbers their cylinders beginning at the bellhousing, so the number one cylinder is nearest the clutch, and cylinders two through whatever are closer to the front of the engine. I don't know if Mitsubishi numbers their machines similarly. You should be able to figure out which cylinder fires first just by slowly turning the motor with the valve cover off and synchronizing the fuel pulses from the pump to the valves closing.
My manuals for my Mitsubishi tractors do not have a list of which cylinder is number one, but the firing order is 1-2 on the two cylinder S370, according to my service manual.
