Getting warmer... I tested the spark (unfortunately ungrounding it for
second and thus grounding it through me - that felt good) and all is OK.
Timing is good - all marks line up.

But I think I figured out what's not working right. I pulled one of the
injectors (one of the two that I was able to get out), blocked the injector
hole to prevent an air leak, and operated the fuel distributor manually by
pressing directly on the air plate mechanism. First, the injector does not
spray at all for about 6 seconds, then, when it does spray, it pulses
(sprays fuel intermittantly) until I raise the air plate by about an inch or
two. Then it sprays regularly. So I'm figuring I have a fuel pressure
problem. I'm going to check that the fuel pump is delivering enough fuel
(the Bentley says 17 oz. in 30 seconds) If that seems OK, then I guess it
can only be the fuel lines (that I made using 200 PSI hydraulic line based
on a recommendation from a list member and a hydraulic shop and they seem
OK), the control pressure regulator, or the fuel distributor itself. The
only way to test this stuff is with a pressure gauge which I'll have to buy
unless someone in San Diego has one to borrow.

So any advice on testing procedures from the list? I'm also still trying to
identify the two-wire connector that is on the fuel distributor - I can't
figure out what this goes to...
