Injector Driver Question
hi all,
i have a 93 camry with 3.0 3vz-fe engine and auto trans.
im having a problem with the #4 injector staying open and dumping fuel into the cyl as soon as the ignition is turned on and while running. i know that the injector is directly controlled by the ecu so my question is; what sends the ecu the signal to open a specific injecor or what other circuit could impact the operation of the injector driver?
i have installed a new injector and tested the wire between the injector and the ecu with no faults.
any advice is greatly appreciated!!
aloha
