- INSPECT FUEL PMP RELAY
- Inspect the FUEL PMP relay (Refer to PROCEDURE - Step 3 ).
Result:
NG
REPLACE F/PMP RELAY
Result:
OK
See step 2
- CHECK TERMINAL VOLTAGE (FUEL PMP RELAY)
- Remove the FUEL PMP relay from the engine room relay block.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition 2 (FUEL PMP relay holder) - Body ground Cranking 11 to 14 V 2 (FUEL PMP relay holder) - Body ground Ignition switch ON 0 to 3 V TEXT IN ILLUSTRATION*1 Engine Room Relay Block *2 FUEL PMP Relay Holder
