ECM & Fuel Pump Relays
- Two types of relays are used: 4-terminal and 6-terminal. For relay location, see ECM & FUEL PUMP RELAY LOCATIONS table. Remove appropriate relay. Apply battery voltage and ground to terminals No. 1 and 2. See Figure and Figure .
- On 4-pin relays, continuity should exist between terminals No. 3 and 5. On 6-terminal relays, continuity should exist between terminals No. 3, 5, 6 and 7. On all relays, when battery voltage is removed, continuity should not exist. Replace relay, if test values are not as specified.
