What Causes Difficulty in Starting a Car?
2 Answers
Difficulty in starting a car could be due to a damaged starter, a depleted battery, an electrical circuit malfunction, or issues with the ignition system. The following sections explain the possible causes: Spark Plug Failure: Spark plugs are wear-and-tear components that require regular replacement. If spark plugs are used for an extended period without replacement, the electrode gap may widen, affecting the spark plug's ignition capability. Dead Battery: The battery is another wear-and-tear component that needs periodic replacement. Typically, a battery lasts 3 to 4 years. However, improper usage habits can shorten its lifespan to less than 3 years, necessitating earlier replacement.
The other day when I was repairing cars, I often encountered owners saying their cars were hard to start, mostly due to battery issues. After years of use, starting becomes strenuous, and if the voltage is insufficient, the battery terminals might also corrode. If the starter gear is worn out, it might make a creaking sound a few times without the engine turning over, which is also a common cause. If the fuel pump isn't supplying fuel smoothly, such as a clogged filter or an aging pump, the car won't get enough air and the spark plugs won't ignite. Cracked ignition coils leaking electricity or spark plugs with thick carbon buildup result in weak sparks. Poor-quality gasoline can also cause trouble; adding fuel with too much water makes the engine sputter and fail to start. Cold starts are even more troublesome in cold weather, as thickened oil hinders engine rotation. I suggest first checking if any dashboard lights are dim and testing the horn's sound level. If the battery is weak, try charging it; if that doesn't work, go to a professional shop to test the circuits and voltage with proper equipment—don't tinker around yourself, safety first. Regular maintenance and replacing small parts can prevent these issues, saving you the hassle of breaking down on the road.
