1. INSPECT INJECTOR OPERATION
Check operation sound from each injector.
(a) With the engine running or cranking, use a sounc scope to check that there is normal operating noise in proportion to engine rpm.
(b) If you have no sound scope, you can check the injector transmission operation with your finger.
If no sound or an unusual sound is heard, check the wiring connector, injector or injection signal from the ECU.
2. INSPECT INJECTOR RESISTANCE
(a) Disconnect the injector connector.
(b) Using an ohmmeter, measure the resistance between the terminals.
Resistance: Approx. 13.8 Q
If the resistance is not as specified, replace the injecto».
(c) Reconnect the injector connector.
