[Vwdiesel] Jetta just stopped running

  First make darn sure the shutoff solenoid is pulling open.  Swap in the 
one from the other pump, put a plug in its place, pull the plunger and use 
it as a plug only...   If that's fine then make sure you have power to the 
solenoid.    Before you try cranking it over and running the battery down,
fill the pump with fuel (pull the return banjo bolt and fill from there, 
replace 
the bolt.)  If you can get pressure in the tank, fill the supply and return 
lines with fuel as well.  
  The only two ways I know for the pump to actually quit pumping fuel is 
if the vanes wore completey out (not terribly likely) or if the input shaft 
seal is leaking so much air that the pump can't lift any fuel.  
  Other things that come to mind is a brokent timing belt (pump not turning
at all) or a sudden split in a fuel line (sucking air) or a "floater" in the 
tank 
the fuel plugged the line.
  Air filters get pretty cruddy this time of year but that shouldn't make it 
suddenly stop.  A bit overheated can blow the head gasket and make one 
die.
