There is a fuel pump test connection under the hood, near the PCM. It allows you to bypass the relay, and the PCM interlocks to test the pump itself, and the wiring to the pump. The relay is behind the driver's side kick panel. Shoebox has the info you need - these are for a 95, but your 97 will be very similar:
