1. 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 rpm.
(b) If you have no sound scope, you can check the injector
transmission operation with your finger.
If no sound or unusual sound is heard, check the wiring con-
nector, injector or injection signal from the ECM.
2. INSPECT INJECTOR RESISTANCE
(a) Disconnect the injector connector.
(b) Using an ohmmeter, measure the resistance between the
terminals.
Resistance:
Approx. 13.8
If the resistance is not as specified, replace the injector.
(c) Reconnect the injector connector.
