5 Reasons You Can’t Start Your Car Engine

    Reasons You Can't Start Your Car Engine

    As you are about to head out in the morning, suddenly your car just won’t start.

    Who else has experienced such a situation? Yes, the engine refusing to start can give you a headache and ruin your day.

    All vehicle owners surely want their cars to be always in excellent condition. However, having engine problems is not uncommon.

    Several reasons may cause your car engine to fail to start. In this article, we share some of the reasons you can’t start your engine.

    Gear lever fixed at a position other than ‘N’ or ‘P’

    Gear lever position

    Did you know that your car won’t start if you rest the gear lever at D, R, 1, or 2?

    Remember, your car engine will only start if you fix the gear lever to ‘P’ or ‘N’. It is to avoid any potential accident occurring when you start the car engine. This is also to prevent your car from ‘jumping’ or moving on its own once the engine is started.

    Therefore, ensure that your gear is fixed at the right position before turning on the car engine.

    Dead car battery

    A car battery is essential in supplying electrical power to the car engine. Typically, a car engine won’t start due to a depleted car battery.

    For your information, a car battery will start to lose its power after 12 to 15 months of use.

    Several reasons deplete a car battery, including:

    • Not turning off the vehicle lights
    • The car has not been in use for a while
    • The battery has been used for a long time and needs to be replaced

    If the car battery has been in use for more than a year, you can unplug the car battery and have it charged at a nearby workshop. However, a recharged old battery will become weak again after a few days.

    You should get an expert’s view on whether you can use the same battery or have it replaced with a new one.

    Some of the signs that your spark plug is damaged are:

    • Your car engine is unusually noisy
    • Uneven combustion
    • Unable to start the engine especially in the morning
    • The engine squeaks while the acceleration power decreases

    If you find your car showing such symptoms, please send your car to a workshop to replace your spark plug.
