well the enigne if it really is frozen is toast. sounds like it was run out of oil.

I assume the starter is engaging and trying to turn the motor over, but for some reason, the motor will not turn over.
If this is the case, I'd remove all the spark plugs and see if the engine will turn over. If it will, look for liquid that might be blown out of one (or more) of the empty plug holes.
If all this occurs, then it sounds like the engine was hydro-locked: a liquid (likely coolant) leaked into one or more cylinders (likely bad lower intake manifold gasket) and caused the engine to "lock up" (liquids will not compress like air/fuel mixture will.)
Give it a shot and get back in touch.

Thanks
