Here’s the Fix for a Car That Won’t Start and Makes No Noise
When you turn the key in the ignition and your car won’t start, it can be frustrating and worrisome. If there is no noise at all, it can be difficult to determine the cause of the problem. However, there are several potential reasons why your car won’t start and no noise is being made.
One of the most common culprits is a faulty starter solenoid. This cylindrical object sits on top of the motor and is responsible for pushing out the pinion and completing the circuit so the starter motor turns. If the starter solenoid is not working properly, your car won’t start and no noise will be made.
Another possible cause is a dead battery. If your battery is not providing enough power to start the car, you may not hear any noise when you turn the key. Other potential causes include a faulty ignition switch, a bad starter, or a blown fuse. By understanding the potential reasons why your car won’t start and no noise is being made, you can take steps to diagnose and fix the problem.

Battery Issues
When a car won’t start and there is no noise, it’s often due to a battery issue. The battery is responsible for providing the necessary power to start the engine. If the battery is dead or not supplying enough power, the car won’t start. Here are some steps to troubleshoot battery issues.
Check the Battery Connections
The first thing to check is the battery connections. Make sure they are clean and tight. Loose or corroded connections can prevent the battery from supplying enough power to start the engine. Use a wire brush to clean the battery terminals and cable clamps if they are dirty or corroded. Tighten the clamps with a wrench if they are loose.
Test the Battery Voltage
If the battery connections are clean and tight, the next step is to test the battery voltage. A fully charged battery should have a voltage of around 12.6 volts. Use a multimeter to test the battery voltage. If the voltage is low, the battery may need to be charged or replaced.
It’s important to note that a battery can lose its charge over time, especially if the car is not used frequently. If the battery is more than three years old, it may be time for a replacement.
Starter Problems
When a car won’t start and there’s no noise, one of the most common culprits is a starter problem. Here are some sub-sections to help diagnose and fix starter problems.
Check the Starter Connections
If the starter connections are loose or corroded, the starter may not work properly. Check the connections at both ends of the positive and negative battery cables, as well as the connections at the starter motor and solenoid. If any of the connections are loose or corroded, clean them with a wire brush and tighten them securely.
Check the Starter Solenoid
The starter solenoid is a cylindrical object on top of the motor that pushes out the pinion and completes the circuit so the starter motor turns. If the solenoid is faulty, it may not engage the pinion or complete the circuit, preventing the starter motor from turning. To check the solenoid, use a circuit tester to see if there is power in the wires connected to it. If there is power but the car doesn’t start, the solenoid may be faulty and need to be replaced.
It’s important to note that a bad starter can also cause a car to not start and make no noise. Signs of a bad starter include a clicking noise when turning the key or pushing the start button, or lights turning on but no action from the starter. If the starter connections and solenoid are both in good condition, it may be time to replace the starter.
Ignition Switch Issues
When a car won’t start and there is no noise at all, it could be due to a faulty ignition switch. The ignition switch is responsible for supplying power to the starter motor, ignition system, and other engine controls. If it fails to do so, the engine won’t start.
Check the Ignition Switch Connections
One of the common causes of ignition switch issues is loose or corroded connections. The connections between the battery and the ignition switch, as well as the ignition switch and the starter motor, should be checked for any signs of damage or corrosion. If any issues are found, they should be fixed immediately.
Replace the Ignition Switch
If the connections are fine, the ignition switch itself may be faulty and need to be replaced. This is a more complex job and may require a mechanic’s expertise. However, if you are confident in your abilities, the following steps can be taken:
- Disconnect the battery to prevent any electrical shocks or damage.
- Remove the steering column covers to access the ignition switch.
- Disconnect the wiring harness from the switch.
- Remove the mounting screws and remove the old ignition switch.
- Install the new ignition switch, making sure it is properly aligned and secured with the mounting screws.
- Reconnect the wiring harness to the new switch.
- Reinstall the steering column covers.
- Reconnect the battery.
It’s important to note that some cars may have a more complicated ignition system that requires additional steps or tools to replace the ignition switch. In these cases, it may be best to seek the help of a professional mechanic.
Fuel System Problems
If your car won’t start and you don’t hear any noise, the issue could be related to the fuel system. Here are some sub-sections to help you diagnose and fix the problem.
Check the Fuel Pump
The fuel pump is responsible for delivering fuel from the tank to the engine. If the fuel pump is not working properly, the engine won’t receive the fuel it needs to start. Here are some steps to check the fuel pump:
- Turn the key to the “on” position and listen for a whirring sound. This is the fuel pump priming the system.
- If you don’t hear anything, check the fuel pump fuse and relay. These are usually located in the engine compartment or under the dashboard.
- If the fuse and relay are okay, use a multimeter to check the voltage at the fuel pump connector. If there is voltage, the pump may be faulty and need to be replaced.
Check the Fuel Filter
The fuel filter is responsible for removing impurities from the fuel before it reaches the engine. If the fuel filter is clogged, the engine won’t receive the fuel it needs to start. Here are some steps to check the fuel filter:
- Locate the fuel filter. It is usually located in the fuel line between the tank and the engine.
- Remove the fuel filter and inspect it for debris or clogs. If it is dirty, replace it.
- If the fuel filter is clean, use a multimeter to check the voltage at the fuel pump connector. If there is voltage, the pump may be faulty and need to be replaced.
Conclusion
All in all, when a car won’t start and there is no noise, it can be a frustrating and confusing experience. However, there are several potential causes and solutions that can be explored.
Firstly, it is important to check the battery and ensure it has enough charge. If the battery is dead, it may need to be replaced. Additionally, checking the battery connections and cleaning any corrosion can also help.
Another potential cause could be a faulty starter solenoid. This cylindrical object on top of the motor can prevent the pinion from pushing out and completing the circuit, which in turn prevents the starter motor from turning. Checking the starter solenoid and replacing it if necessary can resolve this issue.
It is also important to check the fuel system, including the fuel level and pump. If the battery and starter are functioning properly, the issue may be related to the fuel system.
Other potential causes include a faulty ignition switch, damaged flywheel, or bad engine coolant temperature sensor. By following the steps outlined in the search results and consulting with a mechanic if necessary, these issues can be diagnosed and resolved.
Overall, troubleshooting a car that won’t start and has no noise requires patience and diligence. By checking the battery, starter solenoid, fuel system, and other potential causes, drivers can get their car back on the road in no time.
