Troubleshooting Guide: Why Your 2018 Hyundai Sonata not Crank and How to Fix It

Are you having trouble starting your 2018 Hyundai Sonata not crank? If your vehicle won’t crank, it can be frustrating and stressful. In this article, we will discuss common reasons why your Hyundai Sonata may not be starting and provide you with a troubleshooting guide on how to fix the issue. By following the steps outlined in this guide, you can potentially save time and money on unnecessary repairs.

1. 2018 Hyundai Sonata not crank : Is the Battery Dead?

One of the most common reasons why a car won’t crank is due to a dead or weak battery. If you turn the key in the ignition and nothing happens, it may be a sign that the battery is not providing enough power to start the engine. You can try jump-starting your vehicle using jumper cables and another vehicle with a charged battery. If the car starts after jump-starting, the issue is likely the battery.

Another way to check the battery is to turn on the headlights. If the lights are dim or flickering, it may indicate a weak battery. In this case, you may need to replace the battery with a new one to solve the issue.

2. 2018 Hyundai Sonata not crank : Is the Starter Motor Faulty?

If the battery is not the issue, the next thing to check is the starter motor. A faulty starter motor can prevent the engine from cranking when you turn the key in the ignition. To test the starter motor, you can try tapping it gently with a hammer while someone else tries to start the car. If the car starts after tapping the starter motor, it may be a sign that the motor is failing and needs to be replaced.

3. Is the Ignition Switch Malfunctioning : 2018 Hyundai Sonata not crank?

The ignition switch is responsible for sending electrical power to the starter motor when you turn the key in the ignition. If the ignition switch is faulty or malfunctioning, it may prevent the engine from cranking. You can test the ignition switch by checking if other electrical components, such as the radio or headlights, are working when you turn the key. If these components do not turn on, the issue may be with the ignition switch.

4. Are the Spark Plugs Worn Out?

Old or worn-out spark plugs can also prevent your Hyundai Sonata from starting. The spark plugs are responsible for igniting the fuel in the engine cylinders, and if they are dirty or worn, they may not provide a strong enough spark to start the engine. You can check the spark plugs for signs of wear or corrosion and replace them if necessary.

5. Is the Fuel Pump Working Properly?

The fuel pump is responsible for delivering fuel from the tank to the engine. If the fuel pump is malfunctioning or failing, it can prevent the engine from starting. You can test the fuel pump by listening for a humming noise when you turn the key to the “on” position. If you do not hear the noise, the fuel pump may be faulty and need to be replaced.

6. Are the Fuel Filters Clogged?

Clogged fuel filters can restrict fuel flow to the engine, leading to starting issues. If the fuel filters are dirty or clogged, they can prevent the engine from getting the proper amount of fuel to start. You can inspect the fuel filters for debris or blockages and replace them if necessary to resolve the issue.

7. Is the Engine Control Unit (ECU) Malfunctioning?

The Engine Control Unit (ECU) is responsible for controlling various engine functions, including starting the engine. If the ECU is malfunctioning or experiencing issues, it can prevent the engine from cranking. You may need to have the ECU scanned for error codes using a diagnostic tool to determine if it is the cause of the starting problem.

Conclusion

In conclusion, if your 2018 Hyundai Sonata not crank, there are several potential reasons for the issue. By following the troubleshooting guide outlined in this article, you can identify the cause of the problem and take the necessary steps to fix it.
