6CHECK POWER SUPPLY LINE.
1) Turn the ignition switch to ON.
2) Measure the voltage between fuel injector
and engine ground on faulty cylinders.
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 (–):
#5 (E43) No. 2 (+) — Engine ground (–):

Is the voltage more than 10 V? Repair the poor
contact of all con-
nectors in fuel
injector circuit.
Repair the har-
ness and connec-
tor.
NOTE:In this case, repair
the following item:

tween main re-
lay and fuel
injector on
faulty cylinders
•Poor contact
of coupling con-
nector
•Poor contact
of main relay
connector
•Poor contact
of fuel injector
connector on
faulty cylinders
7CHECK HARNESS BETWEEN FUEL INJEC-
TOR AND ECM CONNECTOR.

#5 (B137) No. 12 (+) — Chassis ground (–):
#6 (B137) No. 13 (+) — Chassis ground (–):
Is the voltage more than 10 V? Repair the battery
short circuit of har-
ness between
ECM and fuel
injector. After
repair, replace the
ECM.

Module (ECM).>
Go to step 8.
8CHECK FUEL INJECTOR.
1) Turn the ignition switch to OFF.
2) Measure the resistance between fuel injec-
tor terminals on faulty cylinder.

No. 1 — No. 2:
Is the resistance less than 1
Ω?
Replace the faulty
fuel injector
to FU(H6DO)-24,

Go to step 9.
9CHECK INSTALLATION OF CAMSHAFT PO-
SITION SENSOR/CRANKSHAFT POSITION
SENSOR.
Is the camshaft position sensor
or crankshaft position sensor
loosely installed?
Tighten the cam-
shaft position sen-
sor or crankshaft
position sensor.
Go to step 10.
10 CHECK CRANK PLATE.Is the crank sprocket rusted or
the teeth of crank plate bro-
ken?
Replace the crank
plate.

ment mark on crank sprocket with alignment
mark on cylinder block.
