12 the 1999 2200 engine an interference one?

You could remove the valve cover and turn the engine to see if the camshaft and the valves are moving. If the valves are moving then the timing belt or chain is not broken, but it could still have jumped timing. I suppose you could, if cam and valves are moving, position the valves on one cylinder in the closed position and apply air pressure to that cylinder via the spark plug hole and listen for air escaping at the exhaust pipe or intake manifold. Not foolproof , but might work.
