Have you ever encountered a situation where you’ve turned your car key only to be met with a disheartening silence, leaving you stranded and frustrated? A failing starter motor can be a major inconvenience, especially if you’re in a hurry or far from assistance. Fortunately, there are some clever techniques you can employ to start your car even with a bad starter. These methods offer temporary solutions that will allow you to reach your destination or a nearby mechanic for professional repairs.
One effective method is known as “rocking.” This technique involves pushing your car back and forth while it’s in neutral gear. As you build momentum, quickly turn your ignition key to the “Start” position. The rocking motion can help the starter motor engage with the flywheel, potentially allowing the engine to crank and start. Additionally, you can enlist the assistance of another vehicle to jumpstart your car. However, it’s crucial to ensure that both vehicles have compatible battery systems to prevent any electrical damage. Carefully connect the jumper cables, following the proper polarity, and start the donor vehicle first.
Furthermore, if you have access to a manual transmission vehicle, you can attempt the “bump start” method. This technique involves pushing the car while it’s in gear and the ignition is turned on. As you push, slowly release the clutch pedal, allowing the engine to engage. If the timing is right, the engine will crank and start on its own. It’s important to note that bump starting can put additional strain on your clutch, so it should only be used as a last resort. By implementing these techniques, you can overcome the temporary setbacks caused by a bad starter and get your car running again.
Identifying Starter Issues
The starter is a crucial component that kick-starts your engine by engaging the flywheel. When it’s faulty, it can lead to frustrating starting problems. Here are some telltale signs:
1. Grating or Grinding Noises
When you turn the key, a healthy starter should produce a smooth whirring sound as it engages with the flywheel. However, if you hear a loud grating or grinding noise instead, it indicates worn-out gear teeth or a misaligned starter. This issue requires immediate attention to prevent further damage to the starter or flywheel.
| Symptom | Possible Cause |
|---|---|
| Continuous grinding | Worn starter drive gear |
| Grinding noise only when starting | Misalignment between starter and flywheel |
2. Whining or Screeching Noises
Another audible symptom of a bad starter is a high-pitched whining or screeching sound while attempting to start the vehicle. This noise usually originates from a worn-out starter solenoid, which is responsible for engaging the drive gear. The solenoid may need to be replaced or repaired.
3. Click-Clicking Sound
When you turn the key and only hear a series of rapid clicking noises, it suggests a problem with the starter’s electrical system. The most likely culprits are a weak battery, a faulty starter relay, or a corroded connection between the starter and the battery or ground.
Checking the Battery
The battery is the main power source for your car’s starter, so it’s important to make sure it’s in good working condition. Here are how to check the battery:
Check the Terminals
The battery terminals should be clean and free of corrosion. If the terminals are corroded, you can clean them with a wire brush or a battery terminal cleaner. Be sure to wear gloves and eye protection when cleaning the terminals.
Check the Battery Voltage
You can use a multimeter to check the battery voltage. The voltage should be between 12.6 volts and 13.2 volts. If the voltage is below 12.6 volts, the battery may be weak or discharged. If the voltage is above 13.2 volts, the battery may be overcharging.
Check the Battery Cables
The battery cables should be in good condition and securely connected to the battery terminals. If the cables are damaged or loose, they can prevent the battery from providing power to the starter.
| Battery Voltage | Battery Condition |
|---|---|
| 12.6 volts – 13.2 volts | Good |
| Below 12.6 volts | Weak or discharged |
| Above 13.2 volts | Overcharging |
Inspecting Battery Terminals
When the battery terminals are corroded or loose, they can prevent the starter from getting enough power to crank the engine. To inspect the battery terminals, follow these steps:
- Locate the battery. It is usually located under the hood in the front of the vehicle.
- Look at the battery terminals. They are the two metal posts on top of the battery.
- Check for corrosion. Corrosion is a white or blue-green powder or crust that can build up on the battery terminals. If you see corrosion, it must be cleaned off.
- Check for loose connections. If the battery terminals are loose, they can be tightened with a wrench.
Tips for cleaning battery terminals:
| Method | Materials | Instructions |
|---|---|---|
| Baking soda |
|
|
| Vinegar |

Removing the Starter
Once you have located your starter, you will need to remove it in order to access the solenoid. The process for removing a starter varies depending on the vehicle, but the following general steps can be followed:
1. **Disconnect the battery**. This is important to do for safety reasons, as it will prevent the starter from being powered during the removal process.
2. **Locate the starter mounting bolts**. These bolts typically secure the starter to the engine block or transmission. Once you have located the bolts, remove them using a wrench or socket.
3. **Gently pull the starter away from the engine**. Do not force the starter, as this could damage the starter or the engine. If the starter is stuck, you may need to use a pry bar to gently pry it loose.
4. **Disconnect the electrical connections to the starter**. Once the starter is loose, you will need to disconnect the electrical connections. These connections include the battery cable and the solenoid wires. Use a wrench or pliers to remove the nuts or bolts that secure the connections.
5. **Remove the starter**. With the electrical connections disconnected, you should now be able to remove the starter from the vehicle. Inspect the starter for any obvious signs of damage. If there is any damage, you will need to replace the starter. Otherwise, proceed to the next step.
Inspecting the Starter
If the starter is suspected of being faulty, a thorough inspection should be conducted. Here’s a detailed guide to help you identify potential issues with the starter:
Visual Examination
Begin by inspecting the starter’s exterior for any obvious signs of damage, such as cracks, loose connections, or burnt wires. Check the solenoid for any loose or broken parts, as well as the electrical terminals for any corrosion or loose connections.
Electrical Connections
Using a multimeter, test the voltage at the starter’s terminals. With the ignition switch in the “Start” position, the voltage should be around 12 volts. If the voltage is substantially lower or completely absent, this indicates a potential electrical issue.
Armature and Brushes
Remove the starter and carefully inspect the armature and brushes. Look for any signs of wear, corrosion, or pitting on the armature. Check the brushes for proper contact and ensure they slide smoothly within their holders.
Field Windings
Using a multimeter set to the ohms scale, measure the resistance across the field windings. The resistance should be within the manufacturer’s specified range. If the resistance is significantly higher or lower, it may indicate a problem with the field windings.
Solenoid
Test the solenoid by applying 12 volts directly to its terminals. The solenoid should engage and move the starter’s gear into the engaged position. If the solenoid does not engage, it may be faulty.

How to Start a Car with a Bad Starter
If your car won’t start, one of the possible causes is a bad starter. The starter is responsible for turning over the engine, and if it’s not working properly, the engine will not be able to start. There are a few things you can do to try to start a car with a bad starter.
The first thing you should try is to jump-start the car. This will provide the starter with the extra power it needs to turn over the engine. To jump-start the car, you will need a pair of jumper cables and another car with a working battery. Connect the positive terminal of the jumper cables to the positive terminal of the dead battery, and then connect the negative terminal of the jumper cables to a metal surface on the frame of the car with the dead battery.
Once the jumper cables are connected, start the engine of the car with the good battery. Let the engine run for a few minutes to charge the dead battery. Then, try to start the car with the dead battery. If the car starts, you can disconnect the jumper cables.
If jump-starting the car does not work, you may need to replace the starter. This is a more involved repair, but it is still possible to do it yourself if you have some basic mechanical skills.
