Flow under no pressure only really tells you the pump is turning. You need to put it to work, I mean turn steering wheel or even put the pressue gauge in the return line. Like I said before, the relief valve is in pump so you can safely block return.While observeing the flow coming out of return line, turn steering wheel. If front wheels do not turn and flow stays the same that will tell you flow is going right on through bolster valve and cyl. If the flow stops or darn near stops, that tells you it is pump or relief valve. A shot pump will flow almost identical amount of oil with no pressure applied.
