At the injector there are 2 wires, 1 for each injector that receives power supply from the ECM relay.
From ECM relay wire color is Light Green/Black and at injector it is branched into Light Green/Black and black/Blue.
Test the ECM relay and its power supply. since problem is intermittent, I would suspect the relay or its circuit to be faulty.
Item # 9 is the ECM relay.
