If you have no sound scope, you can check the in-
jector transmission operation with a screwdriver.

If no sound or an unusual sound is heard, check the wiring con-
nector, injector or injection signal from the ECM.

3.

(a)

Disconnect the injector connectors.

(b)

Using an ohmmeter, measure the resistance between the
terminals.
Resistance: 13.4 – 14.2

Ω

at 20
