Will a fuel pump from 1997 Camaro work in 1994 Camaro?

Possibly, but it's not guaranteed. While both are Camaros, there were changes in fuel system design and specifications over those three years. The fuel pump's electrical connector, pressure rating, and flow rate might be different. You'd need to compare the specifications of the fuel pump from the 1997 Camaro with the requirements for the 1994 Camaro's fuel system to ensure compatibility. Checking part numbers is crucial, even then, slight differences within the same part number range can exist. It's best to use a parts catalog or a reputable auto parts store's website to confirm compatibility. Using an incorrect pump could damage your fuel system.
