Front cylinder is dead. Have changed plugs, appear to be getting good spark. Ran the diagnostic check on both injectors and one clicks 5 times (which I assume is normal) and the other one doesn't click at all. You hear it turn on but no clicking. I really dont think I'm getting fuel to the bad cylinder. I can smell gas in the cylinder that is firing, but noting in the dead cylinder. Can the injector be repaired or does it have to be replaced? I've read numerous posts, but haven't found too much on fuel injectors. Any help would be greatly appreciated.
