If the operating arm is on the high part of the cam, you can operated the priming lever, but there is little or no movement of the diaphragm - so no output.
If this is the case, if you turn the engine half a turn on the handle, you will find the pump operating.
It is important, if you take the pump off, to make sure the operating arm goes between the crankcase and the camshaft.
If it is on the wrong side, the engine won't turn over on the handle, and you will break something if you try and force it.
I know this, I must have removed and replace this one particular pump 20 times, and still got it wrong the 21st time.
Realised I had it wrong before any damage, fortunately.
