Fuel Pumps for Chevrolet Impala

Your Chevy Impala’s fuel pump delivers gas to its engine from the gas tank, which makes it a crucial component to getting good gas mileage. A fuel pump failure can disable your Impala and leave you sitting stranded. Diagnosing and replacing a failing fuel pump in your Chevrolet is important to avoid future issues.

What are common causes for a fuel pump to fail?

There are several things that could cause your Chevrolet Impala fuel pump to fail.

  • Loss of power: Fuel pumps use electric power, so a damaged or loose wire can cause a fuel pump failure.
  • Dirt: If an excessive amount of dust and dirt finds its way into the gas tank, this material can end up clogging the pump and its filter. As this happens, the amount of fuel delivered by the pump will slowly be reduced.
  • Rust: Like dirt, rust can flake off a metal gas tank and clog the fuel pump. Especially in older sedans, it’s important to keep the fuel tank full to minimize water condensation.
  • Wear and tear: Time and use can cause any part of your Chevrolet vehicle to fail, and fuel pumps are no exception to this. Driving your vehicle with the gas tank near empty can contribute to wear and tear on the pump and affect your fuel economy, but age will cause all moving parts to fail eventually.
What are the signs of a failing fuel pump?

When a fuel pump begins to fail, it will cause your Impala to exhibit symptoms such as:

  • Hard starts:If your vehicle cranks several times before starting, it may be a clogged or worn fuel pump that is the culprit. Not enough fuel is delivered immediately, so the engine isn’t able to start until after a few seconds.
  • Sputtering engine at high speeds: When a fuel pump begins to fail, it can fail to deliver enough fuel to the engine when driving at highway speeds, causing it to sputter or stall.
  • Surging: A faulty fuel pump can also deliver gas to your Chevrolet engine inconsistently, which can cause the engine to suddenly surge after pressing the gas pedal when you drive.
How do you replace an Impala’s fuel pump?

The pump is mounted on top of your Chevrolet Impala’s gas tank, so replacing it may require you to remove the gas tank first. Make sure the sedans gas tank is empty before removing it. On the other hand, if your Impala was made between 2000 and 2005, it may feature a fuel pump access panel in the back of the trunk.
