Cranking speed is not essential for that pump to work if it's OK. I often turn them by hand and prime them before installing and that's pretty slow. On the engine when cranking it ought to spin at 150 RPM. You stated you had the pump worked on by somebody - so the question remains - was is fixed properly and did it work when you got it? If that pump was off - you could just squirt fuel into it from a hand-held squirt-can (or hook a fuel source to it with a hose) - and then turn the pump by hand and even at one turn per second it will prime itself and inject.
I think you'd better verify #1 that the pump is actually turning inside. That you can verify by removing the little rectangular timing window held on by two screws. Then turn the pump and see if half the parts visible in that window are turning. If nothing is turning - the shaft if broken inside. That shaft is designed to snap in two if the pump turns too hard.
Also, verify the pump is turned "on" via the metering valve linkage.
