Symptom: Back feed through injector circuit causing green INJ/IDC and Red "sys on" led to stay illuminated all the time after starting engine. Shutting off while pump and system still spraying and both leds still illuminated. It will stop when disconnecting pulse signal.
Background: Sequential injection, pin 17 tapped into pulse signal of # 5 injector.
Engine: 2004 Volvo B5254T with ME7 Bosch fuel injection.
Any help would be appreciated.
Thank You.
