Well two days ago my car started running terrible. ECU shows code 51, injector circuit. Checked the resistance on injectors all of them except one are at 11.8 ohms.That one gets no reading whatsoever. Is it possible to get no reading at all from the injector?Also checked the coil packs and there are ok. When car is running disconnected coil pack connectors and all affect car performance except the when were the injector with no reading is at.

yes and open reading from an injector is possible, that means that the winding inside the injector is cimpletely broken and the injector can not function and it shoudl be replaced
