Wondering if someone can help. I recently got a check service engine light and rolled into my local AutoZone. They ran a quick scan of the OBD codes. They told me there may be a problem with the injectors. I was going to remove the fuel rail, and they advised me to remove the fuses from the fuse box for the injectors to avoid popping the fuses. The car was running, and I removed the fuse for injector #s 2 & 4 (fuse position # 8) and noticed that nothing happened, when I removed the fuse for injector 1 & 3 which is fuse position #9, the car shut off. I checked the voltage across the fuses to see what the voltage read. When removing the fuse and checking the voltage for injectors 1 & 3 I got 10.92v which from what I understand is normal but got 0 volts across the fuse on injectors 2 & 4(fuse position # 8)? Does anyone know what may cause this or has anyone had this problem? Or is this normal?
