Fuel Pump Relay: Testing and Inspection

CIRCUIT OPENING RELAY INSPECTION











1. REMOVE CIRCUIT OPENING RELAY
2. INSPECT CIRCUIT OPENING RELAY
A. Inspect relay continuity
- Using an ohmmeter, check that there is continuity between terminals STA and E1.
- If there is no continuity, replace the relay.
- Check that there is continuity between terminals + B and FC.
- If there is no continuity, replace the relay.
- Check that there is no continuity between terminals + B and FP.
- If there is continuity, replace the relay.
B. Inspect relay operation
- Apply battery voltage across terminals STA and E1.
- Using an ohmmeter, check that there is continuity between terminals +B and FP.
- Apply battery voltage across terminals +B and FC.
- Check that there is continuity between terminals +B and FP.
- If operation is not as specified, replace the relay.
3. REINSTALL CIRCUIT OPENING RELAY
