When I turn on the key I get the two relay clicks, the
pump comes on, and a second or so later the relay
clicks and the pump goes of, just as intended.  This
works with all three brains. It also works with the
trigger points plugged in or unplugged (I mentioned
this because of the results below).

OK, the bent wire test; are you ready for this?
1) With the B brain that injects constantly - when I
jump one side one pair of injectors opens, and stays
open after I remove the jumper.  When I jump the other
side the first pair shuts and the other pair opens and
stays open.
2) With the other B or the D brain every time I make
the jump the front (fuel pump) relay clicks and the
pump makes it's one second run, but the injectors
don't do anything.

Methinks something is crossed up, but which wire?
