5 Reasons Why Your Car Won't Start

Sometimes we don’t realize how important is the vehicle in our lives. We use it to drive our kids to school, driving to work, to travel and more. When it gets damaged, we are in big trouble.

There are several reasons why your car won’t start. Let’s look at some most common reasons.

1. Dead battery

One of the most common reasons why your car won’t start is a dead battery . The battery stands to provide electrical power to the vehicle and electrical components, such as lights, radio and so on. When the car is running the alternator charges the battery. If your battery failed, you won’t be able to start your vehicle to use electrical components. There are several reasons why your battery can die:

  • You forgot to switch off your headlights or dome light

  • You have a loose wire

  • You have water inside the component which leads to poor conductivity

  • The battery's lifespan has expired

Some common symptoms include:

  • None of the electrical components work (e.g., the lights, radio, etc.).

  • Battery light is on.

If you are not sure that the problem is with the battery, you can test it by jump starting your car . If the jump start works, you’re most likely dealing with a dying battery or an alternator that is just having trouble recharging the battery. Try to replace the battery or alternator, cleaning the connections, or go to your trusted mechanic to fix the problem.

2. Defective ignition switch

If you found out that your battery is working correctly, but your car still doesn’t want to turn over, then you might have a defective ignition switch . You can determine this issue by turning on your headlights. If they turn on, but your engine isn’t able to start, then a bad ignition switch is the main problem.

3. Faulty starter

One more reason why your car won’t start is a defective starter. A starter is an electrical motor that is connected to the battery. It activates the engine (i.e., pistons, crankshaft, etc.) when you turn the ignition switch on. Once the engine starts, the starter’s job is done. If the starter gets damaged, the engine will not crank properly or may not crank at all when you turn the ignition key on. One of the main symptoms of a broken or weakened starter is a clicking noise when you try to start your vehicle. It is very similar to the bad ignition switch.

Some common symptoms include:

  • The car is not starting when turning the ignition key.

  • Hearing a loud clicking sound when turning the ignition key, but the engine does not start.

  • Very noisy when trying to turn on your car.

4. Clogged fuel filter

If the fuel filter is clogged, the gas won’t be able to reach the engine. It becomes hard for your car to burn the needed fuel to get going. You should change the fuel filters every 20,000 to 30,000 miles, try to replace them during every regular maintenance if it’s possible.

5. Empty gas tank

If you are driving a lot, you may forget to check your gas tank to be refilled. That’s why if your car doesn’t start, first check your gas tank. If it is empty, get more gas and try to turn on your vehicle. If it turns on, it means the empty gas tank was the problem, if not, then move to other common reasons mentioned above. If you cannot solve the problem by yourself, contact a specialist .
