Fuel Pump Inspection
Simulation Test1. Carry out the "Fuel Pump Operation Inspection", "Fuel Pump Control Inspection".
- If not as specified, perform the further inspection for the fuel pump.
Continuity Inspection
NOTE: Perform the following test only when directed.
1. Disconnect the negative battery cable.
2. Remove the service hole cover.
3. Disconnect the fuel pump connector.
4. Inspect for continuity between fuel pump connector terminals B and D.
- If there is no continuity, replace the fuel pump body.
- If as specified but the Simulation Test is failed, carry out the "Circuit Open/Short Inspection".
Circuit Open/Short Inspection
Inspect the following wiring harness for open or short. (Continuity check).
Open circuit
- If there is no continuity, the circuit is open. Repair or replace the harness.
- Ground circuit (Fuel pump connector terminal D and body ground)
- Power circuit (Fuel pump relay connector terminal C and fuel pump connector terminal B through common connector)
Short circuit
- If there is no continuity, the circuit is shorted. Repair or replace the harness.
- Fuel pump relay connector terminal C and fuel pump connector terminal B through common connector to ground.
