What you really want to know is a purely mechanical thing, i.e. "Is the injector lifting off its seat cleanly when pulsed? What is its spray pattern like? Does it deliver fuel at the correct rate?" That sort of stuff.
What I'm leading up to is that I don't think electrical measurements will tell you anything about the important bit inside the injector, the valve itself, that lets the fuel through when opened by current flowing through the winding.

Will
