Why Can't the Car Start?
1 Answers
The reasons why a car cannot start include: starter motor failure; insufficient battery voltage; fuel pump damage; car gear stuck in D position; engine speed sensor (crankshaft position sensor) failure; excessive carbon buildup in the vehicle; or lack of antifreeze. Specific reasons are as follows: 1. Starter motor failure: The typical lifespan of a starter motor is around 100,000 kilometers. Prolonged use can lead to carbon brush wear, causing the starter motor to fail. Timely replacement of the starter motor is necessary. 2. Insufficient battery voltage: This prevents the starter from engaging the engine. The battery needs to be recharged promptly. 3. Fuel pump damage: This results in no fuel supply. The fuel pump must be replaced. 4. Car gear stuck in D position: This is a self-protection mechanism of the car to prevent it from lurching forward after ignition. Simply shift back to the normal gear position. 5. Engine speed sensor (crankshaft position sensor) failure: This causes the vehicle to lack high-voltage spark, preventing normal startup. Replacement is required. 6. Excessive carbon buildup in the vehicle: Regular highway driving can help reduce carbon buildup. 7. Lack of antifreeze: Adding water or low-quality antifreeze to the car can cause the entire cooling system to freeze in extremely cold winter conditions, leading to engine block cracking, water pump failure, inability to start, and damage to other engine components.
