Your compression numbers indicate a blown head gasket at the two low cylinders. Sometimes if your valve adjustment is off it will cause you to get low compression numbers. I'd check the valve adjustment on those two low cylinders looking to see if they are too tight meaning the valves don't close fully during the compression stroke. If not that and it still doesn't start and you know you are getting fuel and its not the glow plugs, then it is most likely a blown head gasket.
