Do a pulleys stop your car for starting?

No, pulleys do not stop your car from starting. Pulleys are part of the engine's accessory drive system. They're responsible for transferring power from the crankshaft to various components like the alternator (which charges the battery), power steering pump, and air conditioning compressor. A malfunctioning pulley *could* indirectly affect starting (e.g., a seized pulley preventing the engine from turning over), but they don't directly prevent the starting process itself. The starter motor is the component responsible for initiating the engine's rotation.
