Subaru Starter Motor Failures

Subaru Fuel System Complications

Your Subaru uses a combustion engine, and therefore to start and run, it needs a mix of enough fuel and air. If your Subaru problems are the result of a faulty fuel system, this can be a clogged fuel filter or a broken fuel pump relay, which could indicate the engine may not be getting the fuel it requires to get the vehicle up and running.

Subaru Electrical System or Wiring Problems

Today’s modern Subaru cars rely greatly on electronics, which can mean there are lots of things that can potentially break and cause problems. Even in an older vehicle, you can have regular issues such as blown fuses, spark plug problems, a faulty ignition switch, a broken sensor and more. These can be some of the many electrical reasons your car won't get started. Symptoms of a circuitry or electrical issue can differ widely but can often include the engine not cranking, or your Subaru can start however just intermittently or various warning lights come on the car’s dash.

Solutions & Repair Tips

Once you have diagnosed what the reason for your Subaru troubles are. The next logical step is obviously to attempt to fix it. Here are some pointers for the common issues we've covered so far.

How to Troubleshoot and Fix Battery Issues in a Subaru

If you suspect it's possible a battery issue is the culprit as to why your Subaru has difficulty starting, then the first thing you must do is examine the battery and check the battery terminals. You want them to be clean, not corroded, and tightly connected. If you find that the terminals are indeed corroded you can try to clean them up with a mix of baking soda and water. If the battery is just old or weak, you will have to replace it, otherwise, even if you charge it up enough to start the vehicle, it will likely deplete quickly again in the not-so-distant future. You can make use of a multimeter as a way to test the life of the battery to find out if it’s worth saving or if it needs replacing. You can ask a professional car mechanic online or locally to provide guidance on this.

If the alternator is what you think is the reason, you can test it. If you can get the vehicle started temporarily (you may need to jump-start the car for that), but when it’s going, let the vehicle run, and while the engine is running, disconnect the positive terminal of the battery. It's likely the result of an issue with the alternator if you discover your Subaru dies pretty quickly when you disconnect the positive terminal. You should be aware however that this method can be dangerous, and may harm the delicate electronic elements in your Subaru, so it's always best to seek advice from a professional car mechanic in your area or online, prior to ever trying this.

You should be able to hear a humming noise for a few seconds. It may be there is an issue with the fuel pump if you are unable to hear this sound.

If different warning lights are visible on your dashboard, it might be a faulty sensor.

Preventive Steps

Routine Maintenance of Your Subaru:

Regular maintenance on car to prevent starting issues

Drive Your Subaru Regularly:

If you happen to leave your Subaru off for long periods of time without taking it for a spin now and again, the battery will run out of charge as it's not receiving any electrical charge from the engine running being in use. Try to drive your car regularly to keep the battery from draining. Take it for a fast spin to make sure there is still a charge in the battery if you remember you have not driven your Subaru in a while. Worth noting: letting the battery fully drain, is also damaging to the long-term life of the battery, try not to do this.

Pay Attention to Warning Signs:

Check Engine Control Light on a Vehicle Dashboard

Chat with a car mechanic in your area or online about these warning symbols and get advice on if they need to be addressed.
