When a Fuel Pump Goes Out

The fuel pump plays an important role in the overall driveability and operation of a vehicle. Without a properly operating fuel pump, the engine will not get the fuel delivery needed to start. There is a necessary fuel-to-air ratio that must be met in order for the engine to get the power needed fuel the cylinders and fire up the pistons.

Because of the unique role of the fuel pump, the signs are often easy to spot. If you notice any automotive malfunctions or changes in your car’s performance, your car might have a bad fuel pump, in which case, your likely recourse is fuel pump replacement.

Common Signs of a Fuel Pump Problem

Failed Ignition Attempts

Can you get your car to start? If you are experiencing multiple failed attempts when trying to start the car, you should have your fuel pump checked out. Most often, this is due to structural damage of the fuel pump itself, but sometimes, the pump is just clogged. If the car will not turn over at all, fuel pump damage is the likely culprit. If the engine cranks but won’t turn over all the way, you may just be dealing with a clogged fuel pump.

Sputtering and Stalling

If your car is routinely sputtering or stalling while driving, it could be an indication of a failing fuel pump. In most cases, the fuel pump is working at a low pressure, so the engine is not getting the fuel it needs to generate combustion. If the car starts, drives away, but then stalls, it is usually because your fuel pump is not doing its job, and the engine cannot keep the car running.

Rear Bumper Whirring

Backseat noises like whirring or humming can point directly back to the fuel pump. These noises are naturally generated by the operation of the fuel pump, but we usually cannot hear them. When the fuel pump starts to malfunction, it is forced to work harder, which can make the noises get louder.   

Engine Surging

Do the engine revolutions randomly surge and swell while you drive? This is a common sign of a faulty fuel pump. Opposite of fuel pump clogs and low pressure, engine surging is caused by a malfunction that sends too much fuel to the cylinders. This often causes the car to suddenly pick up speed and soon after, slow down.

Increased Fuel Consumption

Noticing changes in gas mileage, specifically reduced gas mileage, is a common indication of a fuel system problem. As for the fuel pump, it can be responsible for increased gas consumption when its internal parts and bearings deteriorate or break. Deterioration or damage can cause extra gasoline to be sent to the engine, which goes unused.
