It wont.. Not until the "flapper" is raised, will fuel make it's way to the
fuel injector lines. You only need 3 things: spark, fuel and air.
Assuming the air (compression) is there, do you have spark at the plugs? If
no, find out why. If yes, is the ignition timing correct? If yes, then you
need fuel. You've established the fuel delivery TO the fuel distributor..
A couple of backyard ways to find out if it is indeed a fuel problem, pop
the boot off of the throttle body (TB).. take some carb cleaner and spray a
couple of seconds worth into the TB while holding the throttle open.. Then
try to start it. If it starts and dies, then it's a fuel problem.
To test the fuel delivery, I suggest popping the injectors out of the head
(nows a good time to replace those old o-rings!).. place each injector into
a cup or such, I use pop bottles..
Then turn the ignition to the RUN position. You should hear the fuel pump
energize for a few seconds, pressurizing the system. Now take the rubber
boot off of the fuel Distributor, and using a magnet, attach it to the
flapper, and lift upward. It'll take a strong magnet, as fuel pressure
creates resistance against the arm. If you don't have a magnet, you can use
a pair of needle-nose pliers, and pull up on the flapper, using the center
bolt head. If you have fuel spray (should be a fine mist - drops, streams
indicate bad [dirty] injectors)...
If no fuel, then check the INLET fuel line going to the fuel distributor.
If may still contain the "break-in" screen filter inside the banjo bolt that
is supposed to be removed during it's first VW service, when new. I've seen
these still in place and clogged to the point where the car wouldn't start.
If it isn't in there, then replace it all and we'll go from there...
