Have you ever gotten into your car, turned the key, and heard nothing but a click? It’s a frustrating experience, especially if you’re in a hurry. The dashboard lights come on, but your car won’t crank, leaving you stranded. Imagine this: You’re running late for a big presentation, you get into your car, turn the key, and nothing happens. The radio, headlights, and even the air conditioning are working, but the engine doesn’t even try to turn over. It’s a classic case of a car that won’t start, and the lights come on, but it won’t crank. This is a common problem, but figuring out the cause can be tricky.
Understanding the Problem
The question “car won’t crank lights come on” is a common one for car owners, especially those new to car maintenance. The issue usually signifies a problem with the electrical system, specifically the starter motor, battery, or wiring. From a car mechanic’s perspective, this is a common scenario that often indicates a problem with the electrical system that prevents the engine from getting the necessary power to turn over.
Troubleshooting the Issue
Battery Issues
A dead or dying car battery is the most common reason why your car won’t crank, even though the lights come on. Imagine this: A flat battery can provide enough power to illuminate the dashboard lights, but not enough to crank the engine. The lights are low-power consumers compared to the starter motor. Here’s how to check:
- Use a voltmeter: A voltmeter can check the voltage of the battery. A healthy battery should have 12.6 volts or more. If it’s lower, the battery is likely dead or needs a recharge.
- Jump start the car: A jump start can provide enough power to get your car running. If the car starts with a jump, the battery needs replacement.
Starter Motor Problems
The starter motor is responsible for turning the engine over. A malfunctioning starter motor can prevent the engine from starting even if the battery is healthy. Imagine this: A starter motor can have issues with its brushes, solenoid, or other parts. If the starter motor is not getting enough power, the engine won’t turn over. Here’s how to check:
- Listen for a click: A click when you turn the key indicates a problem with the starter motor or its solenoid. The solenoid acts as a switch that connects the battery to the starter motor.
- Test the starter motor: If you have a multimeter, you can test the starter motor directly for voltage. A low reading could indicate a problem with the starter motor itself.
Other Possible Causes
Besides battery and starter motor issues, several other reasons can prevent your car from starting.
- Corroded battery terminals: Corrosion on the battery terminals can prevent a good electrical connection. Imagine this: Corrosion acts as a barrier, preventing the electrical flow necessary for starting the engine.
- Faulty ignition switch: The ignition switch is responsible for sending power to the starter motor. A faulty ignition switch can prevent the engine from starting. Imagine this: A faulty ignition switch can break the circuit, preventing the power to reach the starter motor.
- Loose or corroded wiring: Loose or corroded wiring can create an open circuit, interrupting the flow of power to the starter motor. Imagine this: Loose wiring is like a broken chain, preventing the electrical current from flowing through the circuit.
- Bad starter relay: The starter relay acts as a switch between the ignition switch and the starter motor. A faulty starter relay can prevent the starter motor from receiving power. Imagine this: A bad starter relay is like a jammed switch, not allowing power to pass through.
What to do if your car won’t crank, lights come on
If your car won’t crank and the lights come on, the best course of action is to contact a professional mechanic. A mechanic can diagnose the problem and recommend the necessary repairs. You can also use a diagnostic tool, like a Dealer Scanner, to get a better idea of what’s wrong.
Here are some tips to help troubleshoot the problem:
- Check the battery: Ensure the battery is properly connected and has enough charge. If necessary, use a jump starter to see if that gets the car going.
- Listen for clicks: A clicking sound when you turn the key suggests a problem with the starter motor or solenoid.
- Check the wiring: Ensure all wiring connected to the battery, starter motor, and ignition switch is secure and free of corrosion.
FAQs about a Car Not Cranking
Q: What if my car is making a clicking sound?
A: A clicking sound when you turn the key usually indicates a problem with the starter motor or its solenoid. The solenoid is a switch that connects the battery to the starter motor. If it’s not working, the starter motor won’t get the power it needs to turn the engine over.
Q: What if my battery is fine, and the starter motor is clicking?
A: A clicking starter motor with a fully charged battery could indicate a problem with the ignition switch, wiring, or a faulty starter relay.
Q: What if I have a new battery but still have this issue?
A: Even with a new battery, a car can still fail to crank. This issue can often indicate a problem with the starter motor, wiring, or ignition switch.
Q: What if I tried a jump start and the car still doesn’t start?
A: If a jump start doesn’t work, it’s likely that the problem is not the battery but the starter motor, wiring, or another part of the electrical system.
Q: I don’t hear any clicking sound at all, what’s the issue?
A: The lack of any clicking sound at all can indicate a completely dead battery, a blown fuse, or a broken wire in the ignition system.
