How to Diagnose a Faulty Fuel Pump with Our San Rafael Mechanics

Auto Repair Specialist • 14 May 2023

Fuel is moved from the gas tank to the engine through the fuel pump. If your fuel pump is damaged, the car won’t be able to start. Below are the most prevalent red flags to look out for when dealing with a faulty fuel pump. When your vehicle needs fuel pump repair, don’t delay visiting Auto Repair Specialist in San Rafael, CA.


Sputtering or Sluggish Engine Performance

If the fuel pump is working properly, the engine should idle smoothly. When the fuel pump fails to supply enough gas to the engine, the engine cannot produce power. This change will be audible and can be felt as well. When you turn the key, your car may splutter or idle unevenly, indicating that it is not receiving fuel. Besides causing internal engine damage, this problem can also make for a bumpy ride.


Lowered Fuel Efficiency

If your vehicle generally gets good gas mileage but starts consuming massive amounts out of nowhere, it could be a fuel pump problem. A failed fuel pump relief valve can result in excess fuel entering the engine. Make an appointment with your local mechanic as soon as you notice you've been stopping at the gas station more often than usual.


Trouble With Acceleration

When driving at a constant speed, a broken fuel pump might cause an unexpected loss of power or engine misfiring. If the gasoline pump motor finds unequal resistance, your vehicle may slow down and struggle to accelerate. As soon as you feel your car straining to accelerate, have it checked out.
