[Vwdiesel] Starting Problem(Update)

[Jdtower23 at aol.com]

I'm the guy who had the '85 Jetta TD with the starting problem...will only 
start with a push start...I replaced the air and fuel filters and pushed it 
to start tonight.....it ran pretty good....drove it about 15 min and shut it 
down....wouldn't start right after shutting it down! doesn't look good....it 
sounds like it's slightly firing(and you can feel it) but its never close to 
starting....almost seems like it's only 2 cylinders trying to fire....very 
uneven....

What do you guys think?
