Flat Battery

One of the most common reasons a car won’t start is a flat battery. This often occurs because of mistakenly leaving the lights on for an extended period, which drains the battery. Additionally, a car that hasn’t been used for a long time or only goes for short journeys can also result in a flat battery. If the battery is too low, it cannot start electrical components, prompting immediate attention. If you double-check the fuel tank and are certain it’s not the problem, call a trusted mechanic to diagnose and fix the problem and determine if a battery replacement is necessary.

Starter Motor Problems

If the battery is not the cause, the mechanic will check the starter motor. This is an electric motor that cranks the engine to start it. If the starter motor malfunctions or fails, the car won’t start. Starter motor issues often manifest as a series of clicks when trying to start a car, which is a red flag you shouldn’t ignore. The auto repair team will check the starter solenoid, an electromagnet that’s used to engage an internal combustion engine or the motor. Dirty or corroded wiring in the starter motor is often the cause, and immediate starter motor replacement may be necessary to mitigate such issues.

Clogged Fuel Filter

The primary role of a fuel filter is to remove contaminants from the fuel before it reaches the engine. Over time, debris and other items can clog your fuel filter, obstructing the right amount of fuel from reaching the engine. While a clogged fuel filter may not raise concerns initially, it can lead to starting issues if left unattended. For diesel cars manufactured after 2015, a lack of AdBlue could lead to the car not starting. Check if a warning light pops up on the dashboard and hire a mechanic to clean or replace the filter.

Spark Plugs

A common cause for petrol vehicles not starting is spark plug issues. Just like the name suggests, a spark plug creates the spark that ignites the fuel/air mixture in the engine. Spark plugs are made of ceramic and metal and are often located at the top of the engine. If one or more spark plugs are defective, the mechanic will check if they are cracked or worn out and replace them. If the spark plugs are not the cause, then the ignition system may be the problem. A diagnostic inspection at a reputable auto repair shop can help determine which cylinders need attention. If some cylinders are misfiring, it may be better to replace all the spark plugs to prevent further damage and recurring start issues.
