Sounds like you have an injector that wasn't firing, or not firing
properly.  All the injectors need to be rebuilt.  Also, the injection pump
more likely than not needs rebuilding.  The head needs to done, with a
perfect valve job.  Have it ported and polished while its out -- make it
nice and smooth.  Did you check compression before you took it apart?  I
can't remember from your earlier posts.  While its out be sure to spring
for a new water pump, and some of the gurus (no apostrophe this time) may
suggest examining your oil pump, and replacing.  I rebuilt a 1.6 TD in
1994.  Didn't know what I was doing, but managed to make it run.  I made a
mistake in trying to cheap out, though, and didn't rebuild the pump or
injectors.  Problems that later had to be addressed.
Of course, if the motorious is out, HK would heartily recommend turboing
that baby so she'll blow nicely.  The one you have can't be done
safely.  Find a 1.9 TD and drop in, then quit worrying about all this other
stuff.  Of course, that might be more than you plan to spend.  But so well
worth it, and would drastically improve value of the van.
