Where is the fuel system relay on a 2002 Chevy Tahoe?

The fuel pump relay location on a 2002 Chevy Tahoe varies slightly depending on the specific trim level and whether it has a specific underhood fuse box or a combination fuse/relay center. It's most likely located in the underhood fuse box, but it *could* also be in the interior fuse panel (less common).

To find it:

1. Locate the underhood fuse box: This is usually a large black plastic box located near the battery, often on the driver's side.

2. Open the fuse box: There should be a cover that releases or opens. You might need a small flathead screwdriver to release clips.

3. Check the fuse box cover or diagram: The cover should have a diagram showing the location of relays and fuses. Look for a relay labeled "Fuel Pump," "Fuel System," or something similar. Sometimes the diagram will use a symbol rather than the full name.

4. If not on the cover: Consult your owner's manual. It will have a detailed diagram of the fuse box.

5. If still not found: The relay *might* be in the interior fuse panel, usually located on the driver's side of the dashboard. Check the owner's manual for this location as well.

Important Note: Before working on any electrical components, disconnect the negative terminal of your battery to avoid electrical shocks or short circuits.
