I have not been following this thread so what I have to offer may
already have been covered.

I had a no start situation with my 1.9 wbx. It had spark. (Verified
by pulling a plug lead and attaching it to a new plug grounded to the
block and spinning the starter.
It had injector firing pulses verified with "noids" (test light that
plugs into the injector connector.)
  The fuel pump was good verified by removing the output line at the
pump, replacing with a piece of fuel line feeding a capture vessel
and shorting across the pump relay (procedure is in bentley) and
measuring volume over time of gasoline delivered.

Repeated the test at the engine end by removing the fuel delivery
line at the pressure regulator.  No volume here.

Solution??? Disconnect hose/fuel line at both ends and blow it out in
both directions with an air line.  (I used 120 psi)

Retest at the engine end for flow.

Mine turned out to be a plugged fuel line.  YMMV

Good luck.
