You have a couple of options.   Do you have a mechanic's stethescope, 
the kind with the metal rod probe? (you might be able to improvise using 
a long screwdriver with the handle stuck in yer ear.)

Anyway, it's easy to hear the injector fire.  It makes a *pink* noise. 
You could also go to the autoparts store and buy a injector test lamp. 
It's a little clear plastic button the size of a quarter, with a small 
bulb in it.  You plug it into the harness, and the lightbulb lights when 
 it gets the signal.

Oh I think you can also use a multimeter to measure the resistance of 
the injector.   The service manual will tell you what it should be... 
but if it's zero or infinite that's probably not good.

Last year my Milano exhibited similar problems.   I went through all the 
steps you've gone through, only to find that the injector screen was 
clogged.   I put in a new injector and all was good.

If you get to the point where you are pulling the injectors, you might 
want to have them serviced.  The electro-mechanical bits almost never go 
bad. I had mine cleaned and blueprinted (you'll get new seals, pintle 
caps, and filter baskets too) by http://www.cruzinperformance.com/ 
$11 per injector.
