It's a common problem that many Subaru owners face: you turn the key, and nothing happens. You try again, and still, the engine won't start. You might start to panic, thinking about the cost of a tow truck or a mechanic's bill. However, before you call for help, there are several steps you can take to diagnose and potentially fix the problem yourself. In this article, we'll explore some common reasons why your Subaru won't start, even if the battery is fine.
Check Your Starter Motor
The starter motor is responsible for turning the engine over when you turn the key. If you hear a clicking sound when you turn the key, but the engine doesn't start, the starter motor could be the culprit. The clicking noise indicates that the starter solenoid is engaging, but the starter motor isn't turning. This could be due to a variety of reasons, including a faulty starter motor, a bad starter relay, or a loose connection between the starter and the battery.
To check your starter motor, you'll need to locate it under the hood of your Subaru. It's typically located near the engine block and is cylindrical in shape. Once you've located the starter motor, check the connections to ensure they're tight and secure. If the connections seem fine, you can try tapping the starter motor lightly with a hammer while someone else turns the key. If the engine starts, the starter motor likely needs to be replaced.
Inspect Your Ignition Switch
The ignition switch is another component that can cause your Subaru not to start. It's responsible for sending power to the starter motor and other electrical components of your car. If the ignition switch fails, your car won't start, even if the battery is fine.
To check your ignition switch, you'll need to remove the steering column cover. Once you've done that, locate the ignition switch and check the wiring for any signs of damage or wear. You can also test the switch using a multimeter to see if it's sending power to the starter motor when you turn the key. If the switch is faulty, you'll need to replace it.
Examine Your Fuel System
If your Subaru won't start, it could be due to a problem with your fuel system. If your fuel pump isn't working properly, your engine won't receive the fuel it needs to start. Additionally, clogged fuel filters or dirty fuel injectors can also prevent your engine from starting.
To check your fuel system, you'll need to locate your fuel pump and check the connections and wiring. You can also test the fuel pump using a multimeter to ensure it's receiving power. If the fuel pump is working properly, you can check your fuel filter and injectors to see if they need to be cleaned or replaced.
Conclusion
When your Subaru won't start, it can be a frustrating experience. However, by taking the time to diagnose the problem, you can potentially save yourself a lot of money and hassle. By checking your starter motor, ignition switch, and fuel system, you can narrow down the cause of the problem and take the necessary steps to fix it. If you're still having trouble getting your car to start, don't hesitate to call a professional mechanic for help.
