– A failing fuel pump can cause the engine to stall or struggle to start, indicating potential fuel delivery problems.
2. Whining Noise
– A whining noise from the fuel tank area can be a sign of a failing fuel pump.
3. Surging Power
– If the fuel pump is pushing too much fuel into the engine, it can lead to power surges while driving, causing speed spikes and drops.
4. Decreased Fuel Efficiency
– A failing fuel pump may lead to lower fuel efficiency, resulting in more frequent trips to the gas station.
5. Difficulty Maintaining Idle
– The vehicle may struggle to maintain idle, indicating irregularities in fuel delivery.
6. Sudden Slowdown and Warning Indications
– A sudden slowdown while driving at high speeds, accompanied by warning indications, can be a symptom of a fuel pump issue.
7. Issues with Cruise Control
– Unintended surging or fluctuations in speed while using cruise control can be a sign of insufficient fuel delivery.
8. No Start or Dead Engine
– A failing fuel pump can prevent the vehicle from starting, as it hinders the delivery of fuel to the engine.
It’s important to note that these symptoms can indicate various issues with the fuel system, and a proper diagnosis by a Subaru specialist is recommended to accurately identify the root cause of the problem.
