What are the symptoms of a bad timing belt on a 2002 KIA Sportage?

Engine stopped suddenly without warning and will not start. This is an interference engine and if the belt broke you will have internal engine damage. Belt should have been replaced at 105,000 miles. If you have less than 105,000 miles it more than likely is not a broken belt. Remove the distributor cap and tun the engine over. If the rotor does not turn the belt may be broken.
