I have seen this a lot, there are a few things that could cause this. Check the seals and springs on the valve plate. Check the hoses for breaks especially near the gear.

The pin is only to fit in the squared slot not the round one. When pump is slid onto shaft correctly there should only be a 1/8" gap from pump to keyway. If installed correctly and still not working try to force prime the pump with a squeeze bottle filled with oil.

Which die head has the problem.#711 &911 or the #714&914.If it is the smaller 711,911, check the trigger assembly #19 on break down.Like i said it needs to be cleaned and some were parts need changed periodically on all types of die heads.(example of were parts in breakdown on die head #711 are #'s 13,1,5,4,6,11,7,15) let me know.
