WB,
Since we don't yet know what happened in your last thread, on the same topic, I'll assume your pump was full of fuel, it was turning, no fuel was squirting out of the pump body with the injection lines removed, and the fuel shut-off lever was in the correct position.
Throttle should be held wide open to prime the pump also.
I hope the pump supplied to you has been set up for the correct rotation, left hand or right hand, sometimes it is indicated on the decal. I would verify that with the supplier.
Your pump should not have any stuck components from long term storage, since it has been tested recently.
It is always a good idea to replace the 2 shaft seals. Engines have been lost through oil dilution.
Remove the pump and mount it in a vise, carefully wrapped with a protective material like an old coat. Tilt the pump so that the drive end is at a 45 deg angle. Construct a rod with a flat end on one end that will fit the slot inside the pump and can be turned with a variable speed drill on the other end. Fill the pump through the shaft hole with the cleanest diesel you have, preferably what drains through your 2 new fuel filters. Think clean here. Supply clean fuel through a short hose to the fuel inlet fitting. A funnel will do. Drive the pump with the drill, slowly at first, the same direction the engine does. Be very careful of the pump bushings, do not rub them with the tool.
Once the pump starts squirting fuel out all 4 holes, reinstall it. Crank the engine with the fuel supply line connected, the fuel return line disconnected , the injection lines off, the fuel shut-off in the correct position, and the throttle wide open. Let us know if this does not work. Phil
