will feel more comfortable with a new one. Paul Conner

Paul,
Someone suggested
slamming the injector down on a 2 x 4 to free it up. I think the
objective here is to try to persuade the plunger to activate. I think
this would be most effective if you directed the forces in the direction of
plunger travel. Seems it would take less force and there would be less
chance of damage to the injector. If I understand how injectors
function, you would want to turn it upside down and hit the inlet side against
the board.
Or, you could order a
new injector. ;-)

Thanks, Mark. I'm thinking
that if I put it in a vise, I might be able to un-flatten it. I will remember
the carb cleaner trick. Thanks again. Paul

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. ;-)

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
