I tried to test the injector signal with a test lamp, but the leads
kept falling out of the plug when I cranked the engine, and I was by
myself.  I am pretty sure (but kinda assuming) that the injectors are
not getting the signal.  The wiring checks good, the injectors ohm
good, and I temp installed the old injectors just in case (no spray).

RE: "I think it is more likely that the injectors are not getting the
signal to open up."  Me too.  What would cause that, besides the ECU?

**side note** It was a major PITA getting the timing light to indicate
spark, I taped the trigger switch down & the wires barely reached from
the battery to the plug wires.  I'll never  be able to actually check
the timing that way...  My remote starter switch is also worthless to
me, considering the battery location.  Is there an easy way to use
these things on a Vanagon, or do I need battery extension cables?
