What are the reasons why a car cannot start but can be push-started?

[GeorgeLynn]

The reasons why a car cannot start but can be push-started are: 1. Insufficient battery power: In winter, the most direct impact on urban family cars is the battery. At low temperatures, the car's power consumption is significantly higher than in other seasons, and the battery's capacity also decreases due to the cold environment. 2. Restricted oil flow: This is more noticeable in extremely cold northern cities. 3. Frozen exhaust pipe or carbon buildup in the electronic throttle: Frozen exhaust pipes mainly occur in cars that are driven short distances between home and work, with low usage frequency. The water vapor from engine combustion freezes in certain parts of the exhaust pipe, and short trips are not enough to melt this ice. After a night, more ice forms, which over time affects the vehicle's starting and exhaust functions.
