Sr20det dead cylinder
I know this has been probably explained a thousand times. But for some reason I can't find the post I'm looking for. So here it goes.
Sr20det cylinder 4 dead. I unplugged the coil packs and also change them and nothing changed for #4 cylinder. I also just replaced all the injectors as well and still the #4 cylinder is dead. I'm just getting stumped and I also did a compression test on all four cylinders and sitting at 150psi. So I just don't know where to look and I also have a fsm but inalways get sidetracked reading it lol. So any help would be nice. |

Well if you've got compression, good injectors and good coil packs, you've got an electrical issue somewhere. What ECU and harness are you running?
Have you verified the injector is actually opening allowing fuel into the cylinder? Have you verified there is spark from the coil pack?
