(a)
Turn the ignition switch to "OFF" position.
(b)
Disconnect cylinder No.3 fuel injector wiring harness
connector EO13.
(c)
Disconnect ECM harness connector EO01.
(d)
Measure resistance between cylinder No.3 fuel injector
wiring harness connector EO13 terminal No.1 and ECM
harness connector terminal No.64. Check whether the circuit
is open. Otherwise, repair the faulty part.
(e)
Measure resistance between cylinder No.3 fuel injector
wiring harness connector EO13 terminal No.1 and a reliable
ground. Check whether the circuit is short to ground.
Otherwise, repair the faulty part.
(f)
Measure voltage between cylinder No.3 fuel injector wiring
harness connector EO13 terminal No.1 and a reliable ground.
Check whether the circuit is short to power supply. Otherwise,
repair the faulty part.
