Why does the car not respond when trying to start?

[LeJourney]

Reasons why the car does not respond when trying to start are as follows: 1. The car has been parked for a long time. The usage time of the car battery is the main cause of power loss. Typically, the lifespan of a car battery is two to three years. If it exceeds this period, the car is highly likely to experience power loss after being parked for just two to three days, resulting in weak starting. 2. Forgetting to turn off the lights and onboard electronics. If interior lights are left on when parking and turning off the engine, the battery may be drained overnight, leading to insufficient power and weak starting. 3. Forgetting to turn off the air conditioning before shutting down the engine. Not turning off the air conditioning before shutting down the engine causes the air conditioning system to automatically start working when the ignition switch is turned on. This directly results in an instant high power load on the vehicle, which over time can cause damage to the battery. 4. Insufficient fuel pressure. 5. Poor performance of the fuel pump, spark plugs, or distributor.
