It’s best to promptly visit the shop when you first notice that your car isn’t starting up as easily as it usually does. Otherwise, the underlying issue could soon worsen and prevent you from being able to start your car at all, leaving you stranded. At HESCO Automotive & Performance Center, our local mechanics are experts at diagnosing and fixing issues that cause no-start. Here’s a look at four common reasons that cars fail to start up.

Dead Battery

A dead battery is one of the most common reasons for a no-start condition. When you turn the key and get no response, it’s often due to a dead battery. Another sign is hearing a clicking sound when attempting to start the car. Batteries can die for various reasons, such as leaving lights on, a faulty alternator, or simply because the battery has reached the end of its lifespan. 

Faulty Starter Motor

The starter motor is responsible for turning the engine over when you start your car. If the starter motor fails, the engine won't crank, and the car won't start. Common symptoms include a clicking noise when turning the key, but no engine crank. This problem can arise from wear and tear or electrical issues within the starter. 

Fuel System Problems

The fuel system is vital for providing the engine with the necessary fuel to start and run. Problems such as a faulty fuel pump, clogged fuel filter, or empty gas tank can prevent the engine from starting. Symptoms include the engine cranking but not starting. Common signs that fuel system issues are developing include poor acceleration and decreasing fuel-efficiency.

Faulty Spark Plugs

Spark plugs are responsible for igniting the air-fuel mixture in the engine cylinders. If they are worn out or damaged, they can prevent the engine from starting. Warning signs of faulty spark plugs include rough idling and misfiring. Regular maintenance and replacement of spark plugs are crucial to help ensure your car starts reliably.
