My poor Westy died, and I don't know where to go from here- help?

It was running poor, loss of power, stumbling, etc, which I think I
narrowed down to the AFM.  There were 2 grooves worn into the black
coating, so I loosened the circuit board & slid it forward, and the
van ran great for about 2 days.  Then I drove it to work one morning
(ran fine), but when I tried to go to lunch, it wouldn't start!  The
motor turns over quickly, but doesn't *sound* like it's firing.

Thinking it's a spark problem, I geared up with my multimeter & timing
light (to check for spark through induction), and headed off to the
parking lot.  the timing light will flash on all 5 distrib wires, so
the spark is there, but it sounds like it's not firing....

So I turn to fuel- the pump is running when the ignition is switched
on.  I don't have a pressure gauge, but I took off a fuel line next to
the injectors & there was residual pressure.  So I pulled the left
injectors out to see if they were spraying, and BINGO!, they're not!
I'm excited at this point, because I've found the problem, right?

I did all the VO meter checks on page 24.20 of the Bentley, and
everything checked good.  I ran through a bunch of other FI checks
also (the ones I could do with the motor not running), and everything
checked good.  I checked the relays very thoroughly, because I believe
I'm not getting power switched over to turn the injectors on.  I'm a
bit pissed at the Bentley, because the index lists what is supposed to
be water-cooled Digijet injector troubleshooting on 24.38, but the
tree is obviously for the air-cooled system....

Anybody have any ideas what it could be, or where I should look now?
Thanks in advance!
