Hi Everyone, I've run into a mysterious issue with my Infiniti J30. I was driving home from work, got about a block away, and it died out at the stoplight. When I try to start it, the engine turns over, but it just won't fire up. Not only that, but I had the front windows part of the way down, and they won't move now. (Neither will the back windows, and the retractable antenna retracted about 80% and stopped. The headlights and radio work fine. I've tried jump starting it and charging the battery. I've inspected all the fuses, in the cab and in the engine, and they all look fine. I've even tried that trick to reset the ECM by turning it to diagnostic mode and back twice. Then I even got another ECM from a junkyard and tried that in the vehicle. Nothing seems to work. My OBD tool just says "Error" when I try to read for codes. My theory is that something is wrong with the electrical system that has stopped all electric motors in the car from working, which would keep it from starting (since the fuel pump is electric) and keep the windows and radio antenna from working. But if it's not the fuses, I don't know what it could be. Any ideas?
