Where is the fuel pump relay on a 1995 Buick Riviera?

The fuel pump relay location on a 1995 Buick Riviera isn't standardized across all models (some might have slightly different fuse box layouts). You'll need to consult your owner's manual. It usually resides in either the underhood fuse box or a secondary fuse/relay center, often inside the passenger compartment.

To find it:

1. Consult your owner's manual: This is the most reliable method. The manual will have a diagram showing the location of all fuses and relays.

2. Check the underhood fuse box: This is usually a large black box located near the battery. The cover often has a diagram showing the fuse and relay positions. Look for labels that mention "fuel pump," "EFI," or similar terms.

3. Check for a secondary fuse/relay center (if equipped): Some vehicles have an additional fuse/relay center inside the passenger compartment, often under the dashboard or in the glove box area. Check this location as well.

4. Use a wiring diagram: If you can't find it in your manual or fuse boxes, you can find online wiring diagrams specific to your 1995 Buick Riviera's VIN number (Vehicle Identification Number). This will show the relay's location and circuit. Sites like AutoZone or others selling parts often offer these (often for free).

Important Note: Before working with any electrical components, disconnect the negative battery cable to prevent accidental shorts or injury.
