I feel for ya with the starter problems.  That has been the lone plague for the Lawdog.  I had the same problem, nothing when I turned the key, but I could roll start just fine.  I also found that when it was running I could get the starter to engage and grind.  So the terminals were cleaned.  I worked for a while and then took another dump at Zuwharrie.  There I had to whack it with a hammer.  This was a new starter that I had just dropped $48 bucks on.  So the moral of the story is, as much as the LMS crew has learned about Zuks in general, some problems have to be attacked from all diretions.  Just try everything until the damn thing works again.  Oh, did you check the small wire that tells the starter to engage initially.  Start with that after you have replace the main terminals and wires.  Also check the ground for the starter at the block.  If that fails then replace the starter.  And check that e-mail address that keith posted, or at least shop a couple of parts stores before you shell out 100 bucks for a starter.  Good luck man! Oh, and might I mention that the Lawdog refuses to turn over again. I'm fairly certain it's one of the crappy wires I didn't replace now.
As far as the fuel pump goes, it should make a whining/humming noise when you first turn the key on. If you don't have a meter, listen for that.
