There’s nothing quite as frustrating as a car that won’t start. You’re set to leave for work, an important meeting, or a much-awaited trip, and your vehicle fails you.
Understanding the basics of troubleshooting can help save time, money and the inconvenience of being stranded.
This article guides you through diagnosing and resolving the issues with a car that won’t start, simplifying the process of getting your car back on the road. If you’re having engine troubles, don’t hesitate to reach out to the experts at Yuma Honda.
Check the Battery
A common culprit when your car won’t start is the battery. A dead or weak battery might have enough power to run the car’s electrical components, like the lights, radio, and dashboard indicators but not enough to turn over the engine.
Look for signs of a dead battery, such as dim headlights or a slow-cranking engine. If the battery is over three years old, it might be time to replace it. If you have a voltmeter, a healthy battery should read between 12.4 – 12.7 volts when the car is off.
If you suspect the battery is the problem, try jump-starting your car. If the vehicle starts after a jump, it’s likely the battery. Check if the battery terminals are corrosion-free and clean. If not, the flow of electricity could be hindered.
Test the Starter Motor and Alternator
If your battery is fine, but the car still won’t start, the starter motor or alternator could be the issue. Listen for a clicking sound when you try to start the vehicle. This could indicate a problem with the starter motor.
The alternator charges the battery when the car is running. If it’s not working correctly, it might not recharge the battery, causing the car not to start.
A simple way to check the alternator is to start the car (with a jump if needed) and then disconnect the battery. If the car continues to run, the alternator is likely okay.
Examine the Fuel System
Fuel system issues can also cause a car that won’t start. Check your fuel gauge. It may sound obvious, but sometimes the problem could be as simple as an empty fuel tank.
If there’s fuel in the tank, the issue could be a clogged fuel filter or a faulty fuel pump. You might need professional help to diagnose and fix these issues.
Remember, troubleshooting your car should be done methodically. It’s about ruling out potential problems one by one until you find the source of the issue.
Check the Ignition System
Another cause of a car that won’t start might be the ignition system. If you do not hear any noise when you turn the key, the ignition switch could be at fault. An easy way to check this is to look at the dashboard lights.
The dashboard lights should illuminate when you turn the key to the ‘on’ position (without starting the car). If they don’t, the ignition switch is likely the problem.
A faulty ignition coil or spark plug can also prevent the car from starting. These components are critical for igniting the fuel in your engine.
If you’re comfortable doing so, you can remove a spark plug and check for a strong, bluish spark when the engine is cranked. If you don’t see a spark or it’s weak, you may have an issue with your ignition system.
Inspect the Timing Belt
The timing belt is another crucial part that can cause your car not to start, as it helps the engine’s parts work together correctly. If the timing belt breaks, the engine’s timing fails to synchronize.
This means that the engine’s valves, which control the flow of air and fuel, may not open and close at the right times. When this happens, the engine’s pistons can hit the valves and cause serious damage. With a broken timing belt, the engine may not start because the air and fuel mixture needed for combustion is not properly timed.
Inspecting the timing belt involves removing the timing cover, which can be labor-intensive. If you’re uncomfortable doing this, it’s best to leave it to a professional.
Look for Security System Issues
Modern cars have security systems that prevent them from starting if they detect a problem. This could be as simple as using a key that hasn’t been programmed into the car.
If the security or key light on the dashboard is blinking or stays on when you try to start the car, the issue could be with the security system.
Listen for Strange Noises
Listening to strange noises when you try to start the car can give you clues about potential problems. Grinding noises might indicate a problem with the starter motor, while a whining sound could point to a fuel system issue. A knocking noise might mean there’s a problem with the engine itself.
Consult a Professional
If you’ve tried the above troubleshooting steps and your car still won’t start, it might be time to consult a professional. Some issues, especially those related to the engine or electrical system, can be complex and require specialized knowledge and tools to diagnose and fix.
Conclusion
A car that won’t start can be inconvenient, but understanding the potential causes can help you troubleshoot the problem effectively. Regular maintenance and timely repairs can prevent most car starting issues, ensuring your car remains reliable and ready to go when needed.
Safety should always be your top priority when working on your car. Always wear appropriate safety gear and never attempt to perform repairs beyond your skill level.
