Why is the car weak to start?

[SanBentley]

Car starting weakness may be caused by: 1. The battery's poor charging capacity due to long-term under-voltage, lack of electrolyte, or overcharging; 2. Excessive wear of internal copper sleeves, rotor scraping, or burnt contacts in the engagement switch of the starter motor after prolonged use; 3. Wear of the internal regulator and carbon brushes in the generator. The steps to start a manual transmission car are: 1. Fully depress the clutch pedal; 2. Push the gear lever to engage first gear; 3. Lightly press the turn signal lever downward to activate the left turn signal, alerting vehicles in front and behind; 4. Press the horn button to alert pedestrians in front of the vehicle of the impending start; 5. Release the vehicle's handbrake; 6. Lift the left foot until the clutch reaches the semi-engaged state, causing the vehicle to vibrate slightly; 7. As the vehicle begins to move, release the clutch and gently press the accelerator.
