Three key things are essential for an engine to start: fuel, air, and spark. Fuel mixes with air to be ignited by the spark, initiating the engine's combustion process. Ensure the fuel system is delivering gasoline, the air intake is unobstructed, and the spark plugs are in good condition for reliable engine performance.
