Engine basics: Air + Fuel + Spark = Power just because a starter motor can turn the engine over does not indicate the engine is getting any of the above. Either your spark- plugs / ignition system, Fuel pump / injectors , or air intake is not functioning. You or a mechanic will have to check all of those aspects to determine what is wrong.
