FW: [T3] Compression?


John,
	What you are doing by turning the key on and off is pressurizing the
fuel lines.  You are doing nothing to the compression of the cylindO=u
cannot determine what your compression is without running a compression
test!  
	Based on what this guy has told you so far I would say RUN!!!!!!!
go somewhere else.  He is obviously not versed in the VW FI system and will
probably only cause more harm than good.  With the lists help you can give a
decent diagnosis to or explanation of the problem to someone more familiar
with the system.

The low fuel pressure problem can be caused by leaky fuel lines or bad check
valve in the pump.  You should first have all the original fuel lines
replaced and then see where that gets you.  Don't forget the lines under the
front of the car close to the front.


Thank You,
