Well, if I'm right, it won't make a difference whether you look at voltage  
or current waveform, because they simply tell you about the electrical  
performance of the winding in the injector.  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.

Regards

Will
