we have a 88 c4 with some strange injector harness problems. The injector harness when key to on position has power and ground opening up the injectors and bleeding fuel from the rail into the cylinders. We had tried swapping the ECM fuel computer and had no change in the symptoms.
What would make the ground circuit of the harness be at ground all the time?
We are in the process of unwrapping tha ecm injector lines to check for a ground situation. Has anybody had any similar problem? Please help if possible
Thank you
