If the three relays you see are at the top of the firewall on the passenger side, they are the A/C relays.

Tips for a great answer:
The fuel pump shut-off switch is
located in the passenger's foot well,

FUEL PUMP RELAY INSPECTION
1. REMOVE RELAY BOX COVER
2. REMOVE FUEL PUMP RELAY (Marked: F/PUMP)
3. INSPECT FUEL PUMP RELAY CONTINUITY
(a) Using an ohmmeter, check that there is a continuity between terminal 1 and 2. If there is "NO" continuity, replace the relay.
(b) Check that there is no continuity between terminals 3 and 5. If there "IS" continuity, replace the relay.
4. INSPECT FUEL PUMP RELAY OPERATION
(a) Apply the battery positive voltage across terminals 1 and 2.
(b) Using an ohmmeter, check that there is a continuity between terminals 3 and 5.
If there is "NO" continuity, replace the relay.
5. REINSTALL FUEL PUMP RELAY
6. REINSTALL RELAY BOX COVER
FUEL PUMP RESISTOR
1. REMOVE FUEL PUMP RESISTOR
2. INSPECT FUEL PUMP RESISTOR
Using an ohmmeter, measure the resistance between the terminals.
Resistance: 0.70 - 0.76 W at 20°C (68°F). If the resistance is not as specified, replace the resistor.
3. REINSTALL FUEL PUMP RESISTOR
If all the above components prove satisfactory, then proceed with fuel pump removal.
Access to the fuel pump & sender unit is via a service hole. The service hole is located under the No.1 Rear Seat (through the floor), so you will need to lift the rear seat & carpet, then remove the service cover.
