Thanks for all the help, you guys are great. I'll look at all those things. However, I feel pretty certain it has nothing to do with the turbo. I can hear it spinning up when the revs finally climb up towards 3300 or so, so I know it is not seized. I have a naturally aspirated Rabbit diesel, and no matter if the turbo and ALDA are working like new or completely shot, the engine ought to rev up under zero load pretty quick. There's a blockage of something somewhere, I am almost certain of it. Either that or the pump is shot.

Ahhh...first I have to get it running again, my friend changed the fuel filter and now it won't start. Oh well...
