Paul,
My injectors sat for quite a while and got
all dried out inside. There must have been some gasoline left in the fuel
rails and injectors that dried out over time. When I went to use them, they
wouldn’t “click”. I sprayed some carb cleaner into the
inlets and let it sit and soften up the gasoline residue. Tested them again
(+12v) and they started working and seem fine now. No, I didn’t try the
16# hammer approach. ;-)

injectors
I recall someone posting that you could test to see if an
injector is firing by just attaching 12 volts + and - to the two pins of the
injectors, and you should hear a click. Is this a very subtle click, or
fairly loud and easy to hear? I have the peak and hold type injectors if
that matters at all. (72 lb/hr). I touched the two wires to the
injector's pins, and I believe I was only hearing the faint spark caused by the
wires making contact. After about 5 seconds with the two wires still touching
the pins, the injector got pretty hot. Sound terminal or normal?
I called Dave Atkins and he
said to send the injector to him, and he would check it out. If need be, he has
replacement injectors. Don't know the cost (don't really care, just want one).
Sounded like he was in a hurry, so I didn't keep him on the phone. Thanks for
any info you guys might have to offer regarding testing the injectors,
etc. Paul Conner
