Most likely the ecm has failed as it controls this function.

Well, I am here and you are there. If I had the car, I would scope the actions of this system. It is a very good system when it is tuned correctly. I have done a lot of these with good success. I am giving you my opinion from my expierence and the what you have told me.

Make sure there is 12 volts to the injector on one side as the ecm toggles the injectors based on inputs.
