Ford Repair: Stuck injector, noid light, fire wall

Question
I have a 1994 T bird with a 4.6 auto. The problem is on the number two injector, the injector its self works fine, but the power going to the injector is constant. It will light the noid light from the time the ignition is on and after the engine starts. The others flash on and off but no. 2 stays lit. I checked the wires all the way back to the fire wall and cant find a problem. Could it be the PCM. Thanks Joe

Answer
Hello and thanks for the question...I'll try to help.
Actually ALL of the injectors have power to them at all times......the computer controlls the ground for them....shutting it on and off. IF the light is on constant...the driver for the ground circuit is bad---------the PCM needs to be replaced.
Hope this helps,
Erik
