G4 Plug in on S13 SR20DET Some wiring to the coils was damaged and caused a blown fuse. Half a lap after repairing it the ecu started holding #3 injector to ground. It is back feeding around 9v to the ecu and keeping the ecu alive while the car is off. I cannot fault the wiring and haven't found any issue while plugged in with the software. Everything else works fine. The car still runs as normal on the other cylinders. Unplugging #3 injector removes the back feed and allows the ecu to turn off.
