* Auto Parts Stores: This is your best bet. Major chains like AutoZone, Advance Auto Parts, NAPA Auto Parts, and O'Reilly Auto Parts will either have it in stock or be able to order it for you. You'll need to provide them with your car's year, make, and model. They may also ask for the engine size.
* Online Retailers: Sites like Amazon, eBay, and RockAuto sell auto parts, including relays. Again, be precise with your vehicle information to ensure you get the correct part. Read reviews before purchasing from less reputable sellers on eBay.
* Junkyards/Salvage Yards: A junkyard with Buick Centuries from the mid-80s might have a usable relay. This is the cheapest option but involves more legwork and carries the risk of getting a faulty part.
* Dealership (Last Resort): A Buick dealership will have the correct part, but it will likely be the most expensive option.
Before you buy: It's crucial to verify the correct part number. The best way to do this is to:
1. Locate the existing relay: Find the fuel pump relay in your car's fuse box (usually under the hood or dashboard). The relay itself should have a part number stamped on it.
2. Use the part number: Use this number when searching online or at auto parts stores for the most accurate match.
If you can't locate the part number on the relay, providing the year, make, model, and engine size to the parts store will significantly increase your chances of getting the correct relay.
