If the battery is aging or not charged, it is easy to have difficulty in starting the engine. Two. The ignition system fails. Starting the engine requires the normal operation of the ignition system. If the ignition coil or spark plug ages, it will affect the ignition ability of the engine, causing difficulty in starting.3. Fuel system problems. Fuel is an important substance for engine combustion. If the fuel pump fails or the oil line is blocked, it will cause difficulty in starting the engine. After understanding the above reasons, the problem can be solved. Here are some solutions: 1. Battery problem The battery life is limited. If the owner uses it for a long time or in cold winter weather, it is easy to age or cannot be charged. At this time, the battery needs to be replaced in time.
