Resistor Relay

WARNING: This page is about a different car, the 1989 Mazda RX-7. However, it is still accessible from the selected car via links, so may be relevant.

Remove air cleaner and airflow meter. Disconnect fuel pump resistor. Ensure continuity exists between terminals "a" and "b". See Fig 1 and Fig 2 .
Measure resistance between the following terminals. Resistance between terminals "c" and "d" should be 60-92 ohms and between "e" and "f" should be .70-.94 ohms. If resistor relay does not test as specified, replace relay.
