I have a early 1985 Porsche 944.I have 12 volts on fuel injector plug with key on not running on red wire side and 12 volts on grey wire injector driver side to dme,key on not running with one injector unplugged. when I unplug all injectors I have 12volts on red wire and 10.3 volts on grey wire injector driver side dme,key on not running. Please would someone check to see if this is the same on your running car! I have checked and tested everything I can and it acts like it is out of time when trying to start. Checked timing and everything is lined up,cam crankshaft etc. Only thing I can find is power on grey wire injector plug that I believe is not supposed to have. If I unplug dme and fuel pump relay I do not have continuity or short of injector harness. ThankYou for reading and trying to help me with this nightmare.
