What happens when you try to start car and timing is off?

When you try to start a car with the timing off, the engine may not fire properly, leading to rough idling or failure to start altogether. The misalignment can cause the spark plugs to ignite the fuel-air mixture at the wrong time, resulting in backfiring, poor performance, or engine damage. Additionally, it can lead to increased exhaust emissions and potential damage to engine components if not addressed.
