This step-by-step guide helps diagnose engine starting issues systematically. It covers testing the starter motor, checking battery voltage, ensuring electrical connections are secure, and examining spark plugs for corrosion. Each component's functionality is assessed, including checking for loose or broken wires and belts that might affect performance. If initial checks pass but the engine still doesn't start, it is advised to take the car to a garage for further diagnostics. This ensures thorough troubleshooting and proper maintenance of the vehicle.
