Where is the fuel pump relay located on a 1991 Buick Century?

The fuel pump relay location on a 1991 Buick Century isn't standardized across all models and trim levels. It's usually in one of these places, but you need to consult your owner's manual or a wiring diagram specific to your vehicle for the precise location. The manual will be the most reliable source.

Common locations for relays, including potentially the fuel pump relay, are:

* Under the hood in the relay center/fuse box: This is the most likely place. The fuse box will often have a diagram on the inside of the cover showing the relay positions.

* Under the dashboard: Less common for the fuel pump relay, but some Buicks placed some relays here.

Without knowing your exact trim level and engine size, providing a definite answer is impossible. Using the year, make, and model information along with a search on a site like eBay or a parts website (like AutoZone or Advance Auto Parts) that shows parts diagrams can often help you identify the relay box location and a diagram showing the components.
