[Vwdiesel] I have an idle, but it dies on acceleration

[Mfgavia at aol.com]

The pump is the stock pump from the 1997 Canadian AAZ engine.  I did  
initially start it on fresh fuel from a gallon jug and I noted that there  was 
virtually NO fuel coming out of the pump's return line.
 
I then ran a couple cans of Lubromoly's "Diesel Purge" through it by  
putting the pump's intake and return lines directly in the bottle.  I still  saw 
almost no fuel coming out of the return line, but I did get some rpm  
increase and it ran smoother.
 
When I tried it on diesel fuel again, I was back to where I started with  
little rpm increase and stalling.
 
It sounds like I need to fill the pump with strong stuff, leave it to sit  
overnight, then run it directly on a bottle and really wind the engine  out. 
 
 
Would it be OK to fill the pump with some "Marvel Mystery Oil", or would  
that be too strong a solvent?
 
thanks!

Just wondering, what injection pump are you running on the 1.9  TD?

Is it an old 1.6TD that was sitting or a new 1.9TD pump that only  sat 
those 5 years?
