How do I know if my Subaru fuel pump is bad?

Signs of a Bad Subaru Fuel Pump
If you suspect that your Subaru’s fuel pump may be failing, there are several signs to watch out for:
1. Whining Sound: One of the early signs of a failing fuel pump in a Subaru is a whining sound that seems to come from the fuel tank area.
2. Decreased Fuel Efficiency: A failing fuel pump can cause decreased fuel efficiency due to a lack of proper fuel delivery.
3. Surging Power: If the fuel pump is pushing too much fuel into the engine, you may notice power surges while driving, such as speed spikes and drops.
4. Dead Engine: If the fuel pump is dead, the vehicle might not start because the fuel cannot reach the combustion chamber to start the car.
5. Sputtering Engine: A failing fuel pump can cause the engine to sputter, indicating that the engine is being starved of necessary fuel.
6. Overheating Engine: While an overheating engine is not directly caused by the fuel pump, it can be a symptom of a larger issue related to the fuel system.
7. Rough Idling: If the engine is idling rough and not running smoothly, it could be a sign of a defective fuel pump.
If you notice any of these signs, it’s advisable to have the fuel pump inspected and, if necessary, replaced by a qualified mechanic or authorized service center.
Remember, if you own a Subaru manufactured between 2013 and 2019 and have experienced engine problems such as reduced engine power, stalling, and/or engine shutdown due to a faulty fuel pump, you may qualify to join an investigation or class action lawsuit.
