Unfortunately the engines are "interference" engines so there are bent valves. The 4.2L in those cars used a timing belt not a chain. Still you've probably got multiple bent valves is the belt is broken.
You say it won't start. If there are bent valves there will be very little compression. So when cranking the engine, it will spin a lot faster than usual.
