If your injectors sat around for awhile until you installed them and you
did not check them with a car battery before you installed them, they
may be "stuck". Common problem I have had, especially after they are
cleaned and overhauled, the solvent they use seems to make them stick. I
brought this up before, but if you smack them against a 2x4 and keep
applying voltage, you WILL get them unstuck. As long as you hear a sharp
click when you apply 12v, they are working. I had to do this to many
injectors-now I do it to all, because taking the stinking things out of
a fully dressed engine is way too hard. Try to do this on a 1994 FD with
the sequential dual turbo pneumatic rats nest on top of them....
