Can 4fuel injevtors go out at once? On a 01dodge ram1500 truck
Not likely. I would check for blown fuses. If you find a blown fuse, check each injector coil with a meter. A blown fuse would indicate that one has shorted to ground. Check across both contacts - should read somewhere between 10 and 15 ohms. Not sure but I don't think either side should be grounded. If you find one that is different from the rest, replace it. Use new "O" rings so you don't have to do it twice like I did...
