Tyson:  Hopefully you found it out as I'm a few days behind.
My rant has the test in it. Either black or grey. RE-read:

The part has two screws holding it on.  A pressure regualtor.
By the front pass hood pin near the fuel distributor.
An ohm meter should have a constant 150/200 ohm or so reading across the two
pins with the plug removed.
The point here is that if the Ohm reading increases in value during testing
is an open circuit (infinity - or blinking) that part is clogged OR BAD and
needs replacement.
A used VW quantum or other Audi 5cylinder part will work, but test it first
at the junk yard.
