[VanAlex]

Fault code u0100 can be resolved by checking whether the power supply to the engine control unit (ECU) is normal. The reasons for engine starting difficulties include: 1. The air-fuel mixture being too lean or too rich; 2. Malfunctions in the fuel supply system or intake system; 3. Faulty spark plugs or ignition coils; 4. Severe carbon buildup inside the engine; 5. Aging or loosening of engine mounts; 6. Insufficient cylinder compression. Solutions for engine starting difficulties are: 1. Adjust the air-fuel mixture concentration; 2. Inspect the fuel supply and intake systems for faults; 3. Check if the spark plugs or ignition coils are functioning properly and replace them if necessary; 4. Clean carbon deposits inside the engine; 5. Replace the engine mounts; 6. Use higher-quality fuel.
