For you four-wheeled vehicle users, you may often face the problem of the car not starting when you turn the key. This can certainly make you panic, especially if you are far from a workshop. Don't panic just yet, let's find out the causes of a car not starting and how to overcome it. Check out the full review below.

Causes of a Car Not Starting

A common issue that often occurs when a car won't start is related to the battery and spark plugs. However, there are actually quite a few other problems that can prevent the car from starting. Some causes of a car not starting include:

1. Problematic Spark Plugs

When the spark plugs are problematic, whether due to dirt or damage, it can hinder the spark needed for the starter to work. So when you are starting the car, try to pay attention to the spark plugs in the engine compartment. 

If the spark plugs appear dirty, clean them immediately using a special cleaner for spark plugs.

2. Faulty Alternator or Dynamo

The next cause of a car not starting is a faulty alternator. The alternator itself is a component that is useful for supplying electricity to the battery. 

If this part is damaged, the car will still not be able to start even if the battery is in good condition. Handling a faulty alternator is quite complicated, so it's best to take it to a workshop to be repaired by an expert.

3. Poor Fuel Flow

Next is due to the fuel flow not being distributed properly. This condition is caused by a weakening fuel pump from the tank to the carburetor, and the solution is quite easy, which is to tap the fuel pump in the engine compartment until it functions as it should. 

4. Overheated Coil 

The coil problem itself is related to the coil's function to amplify the electrical voltage towards the battery. Thus, the existing electrical current can flow towards the spark plugs and ignite the spark. 

5. Problematic WTS (Water Temperature Sensor)

If the coil is damaged, then the electrical current to the battery and spark plugs will not be delivered, and the car cannot be started. So for coil and WTS or water temperature sensor issues, you need to check it at the workshop.

New Battery, But Can't Start? Here's the Solution!

Battery problems are the most common and cause the car to be unable to start. However, sometimes after replacing it with a new battery, the car still cannot start. 

Why is that? There are several things that can trigger this, such as battery quality. It could be that the new battery you bought is actually a refurbished battery that is not suitable for use. 

So even though it has been replaced with a new battery, your car still cannot start as it used to. Therefore, when buying a new battery, ensure the authenticity of the battery. Make sure to check the seal, box, and the condition of the battery itself.

Besides being a refurbished battery, another reason for a new battery not starting is that the battery has not been charged. 

Generally, some new batteries do not store enough current and voltage to turn the starter motor and activate the car engine. This problem usually occurs with wet batteries that are not maintenance free or MF.

How to Overcome a Car That Can't Start When the Engine is Hot

The causes of a car not starting have been briefly explained earlier, and issues with the fuel flow system as well as coil problems are the reasons a car cannot start when the engine is hot.

The fuel flow is a system in the car that is useful for safely storing fuel. This flow delivers fuel that has mixed with air to the engine so that the car can start. 

So if your car cannot be started, check the fuel flow. Perhaps this flow only works when the engine is cold and cannot function properly when the engine is hot.

Another possibility that causes the car not to start when the engine is hot is due to an overheated coil. 

The coil is a component in the car that is useful for increasing the electrical voltage in large amounts, which is then directed towards the battery. With the coil, the voltage from the battery, which is initially only 12 volts, can reach thousands of volts.

This high voltage will then flow to the spark plugs. The electrical current will produce the spark.

However, if the coil is too hot, it can burn out and catch fire. Thus, the electrical current cannot be properly delivered to the battery or spark plugs, resulting in the car not being able to start.

The causes of a car not being able to start and run are indeed very diverse. Because a car consists of various very complex components. 

Where all these components work together in a system. As a result, your car cannot start as usual if one of them has a problem. Immediately take it to the nearest workshop to resolve the issue.
