[Vwdiesel] TDI non-start followup

OK.  We went through the system and determined that there's no power to 
the fuel selenoid.  There's still no check engine or glow plug lights on 
start-up either which indicates a failure somewhere in the ECM system.  
I checked the  grounds which were all good.  I checked what I think is 
the power supply lead to the ECM and found 12V.  The common failures 
I've read about involve the 109 relay or the ignition switch, but having 
power to the ECM would seem to preclude those options.  My current guess 
is that the ECM is hosed. 

Anyone know someone capable of testing VW ECMs as a stand-alone unit?  
Barring that, anyone know a cheap source of ECMs?
