first thing check compresson take out one plug at a time hold your thumb over hole if you have compresson it will pop your thumb up check all four this will tell you if any valves are stuck
I would suggest taking all 4 plugs out and squirting some oil into the cylinders before turning it over. The cylinders could probably use the oil. If you start with just one and another is full of water you could bend the crank. The engine will probably need a rebuild if the cylinder is full of water but no need to ruin the crank.
