3. INSPECT INJECTOR OPERATION
Check operation sound from each injector.
(a) With the engine running or cranking, use a sound
scope to check that there is normal operating noise in
proportion to engine speed.
(b) If you have no sound scope, you can check the injec–
tor operating vibration with your finger.
If no sound or unusual sound is heard, check the
wiring connector, injector or injection signal from the
ECM.
4. INSPECT INJECTOR RESISTANCE

(b) Using an ohmmeter, measure the resistance between
the terminals.

If the resistance is not as specified, replace the injec–
tor.
(c) Reconnect the injector connector.
