The 2 Most Common Fuel Pump Problems For 2003-2005 Chevy Cavaliers and Pontiac Sunfires

Sunfire cavalier

Are you having issues with the fuel pump in your Chevy Cavalier or Pontiac Sunfire? This part in 2003-2005 Cavaliers and Sunfires is prone to failure. The most common causes are:

1. Worn Brushes in the Pump Motor

Many Cavalier and Sunfire owners have had their car stall on the road because of this. The fuel pump in these models contains carbon brushes. Brushes are the component that transfers electricity to the rotating portion of the pump motor. The brushes in the OEM fuel pump in the 2003-2005 Cavalier and Sunfire models tend to wear out relatively quickly. If this turns out to be the reason your fuel pump went out, you’ll need to replace the entire fuel pump assembly.

2. Connector Plug Not Making Good Contact

The connector plug is exposed to dirt and moisture, which cause corrosion. It may also vibrate enough over time to loosen up. You can try dropping the fuel tank to clean the connector and then see if the pump starts working again. If that doesn’t do the trick, then the pump likely needs to be replaced.

Why We Recommend Using an OE-Quality Replacement Fuel Pump

Many aftermarket fuel pumps are built without OEM specifications. This means they have a generic design and can be fitted in just about any fuel system. It’s actually a recipe for disaster. Every fuel system is unique and a fuel pump with a generic design will cause all sorts of problems.

Your Cavalier or Sunfire has an OEM fuel pump designed to work specifically with its fuel system. An OE-quality replacement pump is built to OEM specifications. And usually with better materials than OEM to prevent another fuel pump failure in the future.

Because an OE-quality fuel pump is built to OEM specifications, it’s able to work optimally within the fuel system. This decreases the chances of early failure or other problems in the fuel system.
