Need guidance on a '91 TQ 200 20v that won't start

[Ben Swann]

It seems I cover this one once a week.  On these engines that use flywheel sensors, no
fuel is often no spark and something higher up in the ECU control process.  It is all in
how the relay gets triggered on with hall signal and flywheel sensors.  See
http://www.gtquattro.com/FAQ.html for my bent,  and Scott's site is of course excellent.
You may have a momentary fuel pump "prime" but relay not triggering things on
continuously.

If you have fuel spray, you have fuel pump operation, so I'd look to electrical issues.
Review the stuff on Scott Mockry's resourceful website:

Have the Bentley manuals (set of 3 volumes) but they seem to discuss many VW and Vag-Com
tools I will never have access to.

Is there a troubleshooting guidebook that doesn't rely on special test equipment to make
progress in diagnosing a no-start problem?

My car has low miles (26k) and have owned it since new in 1991.  Recently I went to
start it to get the rust off the brakes and no-start, cranks strong, but acts like it is
not getting any fuel.  I changed the large fuel filter in the engine compartment, pulled
the spark plugs and noted they were all dry.  I loosened the front banjo bolt on what
looks like a fuel rail above the fuel injectors on top of the engine and got fuel to
spray out.

Relevant fuse #13 is OK, so I ordered a new fuel pump relay since that would be an easy
to replace low cost possible fix.  In what other areas should I look for a problem?  ]
