To find it, you'll need to consult your owner's manual (if you have it) or a repair manual specific to your 1993 Buick Regal Custom. These manuals will usually have diagrams showing the location of all relays and fuses.
Here are some common places to look for relays in GM vehicles of that era:
* Under the hood in the fuse box: This is the most common location. The fuse box usually has a cover with a diagram showing the location of each relay and fuse.
* Inside the passenger compartment fuse box (sometimes under the dash): Some relays, particularly those related to interior functions, are located here.
To help you narrow it down, look for:
* A relay labeled "Fuel Pump" or something similar: This is the easiest way to identify it.
* A relay that's connected to a fuel pump wiring harness: If you can trace the wiring harness back to the relay, you've found it.
If you can't find it using these methods, consider seeking assistance from a local mechanic or an online forum dedicated to Buick Regals. Providing your engine size (e.g., 3.1L V6, 3.8L V6) might help others provide more specific guidance.
