* Under the hood in the fuse box: This is the most common location. The fuse box is usually located near the battery, but its exact position can vary. The relay may be labeled, or you might need to use a wiring diagram to identify it.
* Inside the car's fuse panel (passenger compartment): Some models placed relays inside the cabin. This is less common for the fuel pump relay, but possible.
* Under the dash: Less likely, but possible.
Without your specific car's documentation, any attempt to locate it based solely on general information is risky. Incorrectly identifying and tampering with relays could cause damage to your vehicle's electrical system.
Use your owner's manual or a repair manual specific to your 1993 Chevy Corsica to accurately identify the fuel pump relay. Online automotive parts stores often have free diagrams available if you provide the correct vehicle information.
