Fuel-Pump Failure: Here’s How to Avoid It

Reading Time: 3 minutes

Without fuel, you’re just not going anywhere. There are a handful of different parts that contribute to your car’s gasoline system, including the fuel pump. It’s instrumental in moving gasoline from the tank and into the engine. No one wants to deal with a bad fuel pump, but it does happen from time to time. Get to know the signs of a failing pump and how to avoid it in the first place. Your engine will last a lot longer in the end.

1. Pay Attention to Unusual Sounds

A healthy fuel pump has a low-key hum to its operations. Most people don’t hear the hum in the first place. An unusual, whining sound may occur when bad fuel pump systems are in play.

Fuel pumps have many small, mechanical parts. Any one of these components can start whining, which ultimately leads to failure. If you notice any sound coming from the pump, ask a professional to check it out. Waiting for a major failure will only cost more in the end.

2. Be Mindful of Surging or Sputtering

Signs of a bad fuel pump includes vehicle surging or sputtering, reports Pep Boys. The pump is designed to offer a steady flow of gasoline to the engine. Malfunctioning pumps can cause the vehicle to surge forward without any action on the part of the driver.

Engine sputtering, on the other hand, produces an entirely different reaction. Driving at freeway speeds requires a lot of effort from the pump. Sputtering occurs when the pump can’t keep up with the engine’s demands.

3. Notice Startup Issues

Most fuel pump tips include attention to the vehicle’s startup sequence. Listen to the engine as you turn the key. It shouldn’t hesitate to turn over. You might hear the engine trying to crank several times before it can truly run.

The most obvious indicator of a bad pump is no engine ignition at all. You might look at the battery, starter or alternator, but a fuel pump can also be part of the problem.

4. Understand Subtle Signs

There can be countless reasons for a part failure, including issues with o-rings in industrial applications, and the fuel pump is no exception. Consider these subtle issues that might point to bad fuel pump systems:

  • Malfunctioning fuel-pressure gauge
  • Vehicle’s temperature rising
  • Less power during hauling
  • Poor gas mileage

These indicators can also involve other vehicle parts, so be thorough with any troubleshooting processes. Early stages of pump failure can be found and solved without too much downtime.

5. Gas up at the Right Time

Many signs of a bad fuel pump won’t arise if you maintain the vehicle on a regular basis. Make sure that you gas up when the tank is around half empty. Don’t allow it to drop down to a quarter of a tank or less. Particles that have dropped to the bottom of your system may float to the top and damage the pump.

Avoid gas stations that are currently filling their tanks with a tanker truck. Their supplies may contain sediment that’s kicked up by the delivery.

6. Store With Care

AGCO Automotive Corporation cautions consumers about storing a vehicle with its fuel inside of the tank. Any ethanol within the fuel mixture can separate and cause issues. If you must store a vehicle, remove all of the fuel from the tank.

When you’re ready to use the vehicle on a regular basis, add fresh fuel to the tank. You’ll avoid long-term issues with the fuel pump as a result.

7. Pick Quality Products

Do you know how to tell if a fuel pump is bad? Question its regular fuel source.

Some people might try to skip the premium fuel and look for shortcuts. Cheap fuel will only damage the system over time.

Ideally, gas up with a well-known supplier. Always use the official pumps that measure and filter the gasoline as necessary. Questionable resources might have suspended particles in the mixture, which may lead to internal damages.

There will always be those unique circumstances where the signs of a failing fuel pump are a bit confusing. Never be afraid to reach out to get help with your situation – we’ll get you back on the road again.
