Locating the Fuel Pump Relay
The fuel pump relay on a 1991 Cadillac Brougham is in the under-hood power distribution center (PDC). Access this relay box easily without special tools for fast identification.
Step-by-Step Access
Follow these steps to locate the relay quickly:
- Open the vehicle's hood and secure it.
- Locate the black rectangular PDC box, mounted near the firewall on the passenger side.
- Release the PDC cover latch and remove the cover to reveal internal relays.
Identifying the Relay
Inside the PDC, identify the fuel pump relay using the following:
- Look for the relay labeled "FUEL PUMP" on the PDC diagram or the relay itself.
- The relay is typically a small, square component in a standard automotive relay slot (e.g., position may vary, but often central).
Always disconnect the battery before handling to prevent electrical hazards.
