The car battery must be disconnected before the fuel pump relay is removed. The car owner can loosen the nuts on the battery clamps using a standard wrench or a socket wrench. The clamps should be pulled off of each terminal, starting with the negative side, and moved away from the battery posts.

Most fuel pump relays are located in a vehicle's fuse box; others are located on the firewall, near the steering column or on the fender cover. The car owner should locate the relay with the help of the vehicle manual and use a screwdriver to remove the lid or casing.
