It is possible that they "click" ok while the fuel orifices are plugged with some gunk. I took mine and safety wired them to the injector manifold, hooked up a fuel supply, hit them with 12v and observed the spray patterns. Probably a waste of time, but it would tell you that you're getting a good mix of fuel into each chamber. BTW, Initially I had incorrectly wired my injector relay. It took me a while to figure out what I had done wrong and correct it. I got it wired correctly now... I think.

Fired up the engine again this morning, and did the following tests:

1)    Triggered the pirimary injectors individually; all clicked as expected.

Al,
You may have answered this already, but have you checked the injector spray patterns?  It is possible that they "click" ok while the fuel orifices are plugged with some gunk.  I took mine and safety wired them to the injector manifold, hooked up a fuel supply, hit them with 12v and observed the spray patterns.  Probably a waste of time, but it would tell you that you're getting a good mix of fuel into each chamber.

BTW, Initially I had incorrectly wired my injector relay.  It took me a while to figure out what I had done wrong and correct it.  I got it wired correctly now... I think.
