The fuel pump relay location on a 1994 Camaro V6 is in the underhood fuse block, specifically in the
Power Distribution Center (PDC). It's not always clearly labeled "Fuel Pump Relay," so you'll need to consult your owner's manual or a wiring diagram to identify the correct relay. The relay itself is usually a standard automotive relay, so it might be labeled with a number.
You'll likely find the PDC near the battery, often attached to the inner fender well. The fuse block will have a cover; carefully remove this to access the relays. Look for a diagram printed on the inside of the cover which should help you locate the correct relay.
