I just  went through troubleshooting an engine with zero compression  
on a  couple cylinders.  If it's that low I'd suggest taking off a   
valve cover and see if the pushrods go in and out when you turn the   
engine before you go much further.  If they do, take the other  one  
off as well and hose the valve stems down with some sort of  penetrant  
or light oil.  Now see if the valves move with the  pushrods.  If you  
still don't have any compression, you may be  looking at a piston or  
valve seat  issue.

Or possibly a slipped crank gear.
