So the engine and radiator are full of coolant? Why did it overheat? The battery has a full charge and battery cables/connections all good? If the cranking rpms sound faster than normal, you may not have any compression? Have helper crank it while you check for spark at the plugs, also, use a gage and check proper fuel pressure and fuel injector pulse? Check for applicable trouble codes? Those are the basic checks, in my opinion.
