1CHECK OPERATING SOUND OF FUEL
PUMP.
Make sure that the fuel pump operates for two
seconds when turning the ignition switch to ON.
NOTE:
Fuel pump operation can also be executed us-
ing Subaru Select Monitor.
Refer to “Compulsory Valve Operation Check
Mode” for procedures. ag)-46, Compulsory Valve Operation Check
Mode.>
Does the fuel pump emit oper-
ating sound?
Check the fuel
injector circuit.

7CHECK HARNESS BETWEEN ECM AND
COUPLING CONNECTOR IN REAR WIRING
HARNESS.
1) Turn the ignition switch to OFF.
2) Disconnect the connectors from ECM.
3) Measure the resistance of harness
between ECM and rear wiring harness con-
nector.
Connector & terminal
(B135) No. 30 — (R15) No. 2:
Is the resistance less than 1
Ω?
Go to step 8.Repair the har-
ness and connec-
tor.
NOTE:In this case, repair
the following item:
•Open circuit
of harness be-
tween ECM and
rear wiring har-
ness connector
•Poor contact
of coupling con-
nector
•Poor contact
of joint connec-
tor
8CHECK HARNESS BETWEEN ECM AND
COUPLING CONNECTOR IN REAR WIRING
HARNESS.
Measure the resistance of harness between
rear wiring harness connector and chassis
ground.
Connector & terminal
(R15) No. 2 — Chassis ground:
Is the resistance more than 1
MΩ?
Go to step 9.Repair short circuit
to ground in har-
ness between
ECM and rear wir-
ing harness con-
nector.
9CHECK FUEL TANK CORD.
1) Disconnect the connector from fuel tank
pressure sensor.
2) Measure the resistance of fuel tank cord.
Connector & terminal
(R60) No. 11 — (R47) No. 3:
Is the resistance less than 1
Ω?
Go to step 10.Repair open circuit
in fuel tank cord.
10 CHECK FUEL TANK CORD.
Measure the resistance of fuel tank cord.
Connector & terminal
(R60) No. 2 — (R47) No. 1:
Is the resistance less than 1
Ω?
Go to step 11.Repair open circuit
in fuel tank cord.
11 CHECK FUEL TANK CORD.
Measure the resistance of harness between
fuel tank pressure sensor connector and
engine ground.
Connector & terminal
(R47) No. 2 — Chassis ground:
Is the resistance more than 1
MΩ?
Go to step 12.Repair ground
short circuit in fuel
tank cord.
12 CHECK POOR CONTACT.
Check poor contact in fuel tank pressure sen-
sor connector.
Is there poor contact in fuel
tank pressure sensor connec-
tor?
Repair poor con-
tact in fuel tank
pressure sensor
connector.
Replace the fuel
tank pressure sen-
sor. EC(H6DO)-10,
