Introduction

If your Subaru starts then shuts off after a few minutes, it can be a sign of many problems. It could be an issue in the fuel system, spark plugs, or even an air filter that is clogged. Knowing the cause of this issue will help you fix it quickly and easily. In this article, we’ll discuss the various reasons why your Subaru may start and then shut off, as well as how to diagnose and repair the issue.

Air Filter

The air filter is an important part of any car’s engine, as it helps to keep dirt and debris out of the engine’s cylinders. If your Subaru’s air filter is clogged or dirty, it can cause your engine to not receive enough oxygen and cause it to shut off after a few minutes. To check if this is the problem, remove the air filter from the engine bay and inspect it for any signs of dirt or debris buildup. If there is buildup, replace the air filter with a new one and see if that solves your problem.

Spark Plugs

The spark plugs in your Subaru are responsible for creating sparks that ignite the fuel in your engine. If these plugs are worn out or faulty, they won’t provide enough spark to keep your engine running properly, which can cause it to shut off after a few minutes. To check if this is causing your issue, remove each spark plug from its socket and inspect them for any corrosion or wear and tear. If they look worn out or corroded replace them with new ones and see if that solves your problem.

Fuel Pump

The fuel pump in your Subaru is responsible for delivering fuel from the tank to the engine cylinders so they can burn it for power. If this pump isn’t working properly due to age or some other issue, it won’t be able to supply enough fuel to keep your engine running properly which can cause it to shut off after a few minutes. To check if this is causing your issue you’ll need to remove the fuel pump from its mounting bracket and inspect it for any signs of damage or wear and tear. If you find any signs of damage replace the pump with a new one and see if that solves your problem

Conclusion

If your Subaru starts then shuts off after a few minutes there could be many causes for this issue such as an air filter that is clogged with dirt and debris, worn out spark plugs that don’t provide enough sparks for ignition, or even a faulty fuel pump that doesn’t provide enough fuel for combustion. Knowing what might be causing this issue will help you diagnose and repair it quickly so you can get back on the road again!
