if you had a cold-start injector it's real easy - remove fuel line at CSI, stick lineinto a safe receptacle, turn key to IGN and pump should fire up and squirt out.
seeing as you don't have CSI it might be easier to detach the line at the fuel filter and point that pipe into a safe receptacle and do the IGN thing.
if you have an external pump it should be obvious where you can remove the line to test for basic functioning of pump.
most modern ECUs will run either do a quick priming pump (run for a few seconds) or run at reduced speed until engine gets up to idle speed.
if you want to test for performance of pump (e.g. pressure) then you'll need some sort of T-adaptor and a fuel pressure gauge. But i'd say that these pumps either work or not.
to remove pump, drain fuel from tank (look in disgust at all the gunk you've just collected from the tank), remove tank from car (exhaust is usually in the way), remove intank-pump from tank, replace with walpro unit (or something similar), re-attach everything in roughly the same order you removed it, turn key to IGN and carefully look for leaks around any fuel pipes you undid.
you can do this youself if you have suitable tools (and petrol containers/funnel/etc), a hydraulic jack and stands (so it's safe to crawl under car) - the ma61 tank is easy to remove (compared to RA40) so MA70 should be about the same? (assuming you have a MA70?)
safety note: have a fire extinguisher and/or hose handy.
