Open circuit in the Yellow/
Red wire.
Turn the ignition switch OFF.
Check the injector coupler for loose or poor contacts.
If OK, then measure the injector resistance.
Disconnect the coupler and measure the resistance
between terminals.
Turn the ignition switch ON.
Measure the injector voltage between Y/R wire and
ground.
