Reasons for difficulty starting and white smoke from diesel vehicles: 1. Low engine temperature: If white smoke appears during startup in winter, it is usually due to the engine temperature being too low and not yet reaching optimal conditions; 2. Water in the fuel supply system: If you place your hand behind the exhaust pipe and water droplets form when the white smoke passes over your hand, it indicates the presence of water in the fuel supply system; 3. Low air pressure in the engine cylinders: If the engine emits white smoke at low temperatures and black smoke when the temperature rises, it suggests that the air pressure in the engine cylinders is too low; 4. Low fuel injection pressure: If the engine emits grayish-white smoke and the vehicle lacks acceleration power after starting, it indicates that the pressure in the fuel injection system is too low.
