Yes, nice and smooth.  It hiccups only after a long time cranking like it just wanted to start but didn't.  When towed, the engine spins smooth, but definately doesn't assist with any power.

Hmm, yeah something might be wrong here.  All lights come-on when you turn the key (including the CEL/MIL).  The glowplug light comes-on, but does not turn-off as it normally should (the glow plugs do not cycle).  When you crank, all lights go-out, and after a long time cranking (and while towing in gear) the glow plug light starts flashing.  So, when towing in gear, the engine doesn't run (and doesn't want to), smokes white and no warning lights on the dashboard light-up - except the glow plug light starts flashing after some time.  The oil light works as it should.  And, the clutch interlock seems to function like it should.   I don't have to have the seat belt plugged-in do I!?

Well, that's a bummer, but not.  Having the right tools is always a help.  Gotta be excited about that!
