Starting a cold diesel engine that won't start involves several steps. First, ensure the battery is fully charged; cold weather can severely impact battery performance. Use a battery heater or engine block heater if the vehicle has been sitting in cold conditions. Check the glow plugs, which are crucial for starting diesel engines in the cold; faulty plugs can prevent starting. Apply a diesel fuel additive designed to aid cold starts. Lastly, avoid cranking the engine for more than 15 seconds at a time to prevent damage. If these steps don't work, it may require professional attention.
