CHECK POWER SUPPLY TO EACH FUEL INJECTOR.

1) Turn the ignition switch to OFF.

2) Disconnect the connector from fuel injector.

3) Turn the ignition switch to ON.

4) Measure the power supply voltage between fuel injector terminal and engine ground.

Connector & terminal

#1 (E5) No. 2 (+) — Engine ground (−):

#2 (E16) No. 2 (+) — Engine ground (−):

#3 (E6) No. 2 (+) — Engine ground (−):

#4 (E17) No. 2 (+) — Engine ground (−):

QUESTION

Is the voltage 10 V or more?

Yes No

Repair the harness and connector.

NOTE:

In this case, repair the following item:

• Open circuit of harness between main relay and fuel injector connector

• Poor contact of main relay connector

• Poor contact of coupling connector
