However, there isn't a single universally agreed-upon location for the fuel pump relay across all 1997 Bonneville trims. You will need to consult your owner's manual. The manual will have a diagram showing the location of all the relays and fuses in your specific vehicle.
If you don't have the owner's manual, you can often find a digital version online through a Pontiac parts website or a general automotive repair manual site. Searching for "1997 Pontiac Bonneville fuse box diagram" should yield results. Look for the diagram that shows the relays, not just the fuses. The relay might be labeled "Fuel Pump" or something similar, or it might be indicated by a symbol.
Important Note: Before working with any electrical components, always disconnect the negative battery terminal to prevent accidental shorts or damage.
