Ensure your diesel engine is ready to start by checking the fuel and oil levels first. Then, turn the ignition key to the 'on' position, allowing the glow plugs to warm up for about 15 seconds. This is critical, especially in cold weather. Once the glow plug indicator turns off, turn the key to start the engine. Do not crank the engine for more than 15 seconds at a time. If the engine does not start, wait for a minute before trying again to prevent damage.
