Possible Causes of a No-Start Issue
If you’ve turned the key and your car’s lights come on, but the engine won’t start, this can be a frustrating experience. Multiple issues can cause a “car won’t start” situation. It’s essential to identify the possible causes and know how to remedy the situation. We’ll explore some common reasons why your car won’t start despite the electrical system functioning correctly.
A car battery can last up to five years before it needs replacing. If your battery is over three years old, it could be weak, causing your car to not start. You can’t always tell that the battery is weak by just looking at it, so you’ll need to use a digital multimeter or a battery tester.
Another common cause of a no-start issue could be a faulty starter. The starter motor draws energy from the battery to start the engine. If the starter motor is not working, it will not turn the engine over, and your car won’t start. You can try tapping the starter motor with a hammer lightly, which could dislodge any stuck parts temporarily.
Issues with the Ignition Switch
Another possible cause of a no-start issue is the ignition switch. If the switch fails, it won’t send a voltage signal to the starter motor, and the car engine won’t turn over. A quick test is to turn on the electrical components, such as the headlights or radio, to see if they are working. If they don’t function, it’s likely the ignition switch has failed.
In this section, we’ve examined the possible common reasons why your lights come on but car wont start come on and ways to diagnose the issue. In the next section, we’ll outline the steps to troubleshoot and fix a no-start issue.
Troubleshooting Steps for a No-Start Issue
If you turn the key, and all you hear is a clicking sound, your car may have a problem with the starter or battery. Follow these steps to troubleshoot the issue:
Step 1: Check Battery Voltage
The first thing to do is to check the battery voltage. Use a multimeter to test the battery and ensure it has enough power to start the engine. If the voltage is lower than 12.6 volts, it’s time to recharge or replace the battery.
Step 2: Inspect the Starter Motor
If the battery is in good condition, the next step is to inspect the starter motor. Check the connections to ensure they are tight and clean. If you notice any loose or corroded connections, clean and tighten them. If the connections look fine, test the starter motor by tapping it with a hammer while turning the key. If the engine starts, the starter motor is faulty and needs to be replaced.
Step 3: Verify the Ignition Switch Function
If the battery and starter motor are both functioning properly, the last step is to verify the ignition switch function. Check for broken wires, burned fuses, or other signs of damage. If everything looks good, try turning the key while wiggling the ignition switch. If the engine starts, the ignition switch is the issue and needs to be replaced.
Following these steps should help you identify and fix the issue of a car that won’t start and only clicks. If you’re not comfortable troubleshooting the problem yourself, it’s always a good idea to seek the help of a professional mechanic.
