What Causes a Car Not to Start After Maintenance?

[DanielLynn]

Here are the reasons why a car may not start after maintenance: 1. Weak Battery: The symptoms include the starter motor turning but not fast enough (lacking power), or the starter motor making noise without turning. Low temperatures in winter or forgetting to turn off certain electrical devices can prevent the car from starting, especially when used for short distances at low speeds for extended periods in winter, causing the battery voltage to drop below the rated value and preventing normal operation. 2. Blocked Fuel Flow: Avoid waiting until the fuel is almost empty to refuel. The symptom is no oil pressure in the engine fuel supply pipe. 3. Poor Ignition System Performance: The symptom is poor fuel atomization in the cylinder due to low intake air temperature, especially in very cold weather.
