Where is the fuel pump relay switch located on a 2003 Chevy Malibu?

The fuel pump relay location on a 2003 Chevy Malibu isn't standardized across all trims and options. It's usually found in one of these places, but you'll need to consult your owner's manual or a wiring diagram specific to your Malibu's year, make, and model for definitive placement. Common locations include:

* Under the hood in the fuse box: This is the most common location. The fuse box is usually located near the battery. The relay itself may be labeled, or you may need to consult a diagram to identify it.

* Under the dashboard: Less common, but some Malibus might have it located within the interior fuse panel, often under the dashboard.

To find it accurately:

1. Consult your owner's manual: This is the best starting point. The manual should have a diagram of the fuse box(es) showing the location of the fuel pump relay.

2. Use a wiring diagram: If your owner's manual doesn't show it, a wiring diagram specific to your 2003 Chevy Malibu is crucial. You can find these online through repair manuals (like Chilton or Haynes) or possibly through a subscription service like AllDataDIY.

3. Look for markings: Once you've located the fuse box(es), look for a relay that might be labeled "fuel pump," "FP," or have a similar designation. The relay might also be identifiable by its size and shape compared to others in the box.

Remember to disconnect the negative battery terminal before working with any electrical components in your vehicle to prevent electrical shock or damage.
