What could be the reasons if the car suddenly doesn't respond when starting?

Improper fuel quality, lack of antifreeze, excessive carbon buildup, starter motor failure, fuel pump supply issues, injector problems, or sensor malfunctions. Below is more information about car starting: 1. Maintenance methods: (1) Check the spark plugs: Normal spark plugs should have intact insulation ceramics. There should be no cracks or leakage, and the spark should be blue and strong. If any abnormalities are found, adjust the gap or replace the spark plugs; (2) Battery maintenance check: Ensure the battery is securely fixed, and the electrolyte level should be between the upper and lower limits. When it's close to the lower limit, promptly add electrolyte or distilled water to reach the upper line. Maintain good contact of the battery's positive and negative cables, and keep the battery clean and dry. 2. Starting tips: Before starting the car, turn the key to the ON position, then back slightly, and then to the START position to ignite. This allows the computer to calculate the water temperature and the appropriate air intake, making the starting process smoother.
I once had a sudden no-start situation in winter, which was really frustrating. Later, I found out it was just a dead battery—even the horn sounded weak. Usually, it's important to remember to turn off the headlights and AC, especially during short trips when the battery doesn't get enough charge. If the remote key fob runs out of power, it can also cause trouble, so keeping a spare battery is essential. If the starter makes a clicking sound but the engine doesn't turn over, it's probably broken. If the fuel pump's humming sound gets weaker, the fuel line might be clogged. For older cars, it's necessary to check the fuse box—there's often a start-related fuse that burns out easily. The worst is when the alternator fails—you could be driving and suddenly stall, which is a nightmare. Keeping a set of jumper cables in the car can be a lifesaver in critical moments.
