Take the spark plugs out, put tranny in neutral with the E-Brake on. If starter won't turn it, put a wrench on the crank bolt and see if it will turn the engine. If it won't turn, engine is probably seized.
The oil light should have come on (assuming it is not burned out) if the pump wasn't pumping. Did you see it come on when it started to hesitate? If the cam is broke, leaving a couple of cylinders with the valves totally closed, removing the plugs will allow the starter to spin the engine, plus you can see if any water comes out of the spark plug holes (i.e. hydrolocked from a massive HG failure).
