Re: Smoke and rough idle!
I had a hard time starting in the recent cold weather, so I replaced the glow plugs, and relay. while doing this I found the bad pigtail. I have been over the pigtail about 5 times now, I even replaced the pigtail for a second time. There were no issues with the glow plugs besides Ohming out bad, came out easy.
The truck was running great except for the hard starts in cooler weather. If I unplug the replaced pigtail the engine wants to die the same as removing any of the four plugs. Is there a wiring schematic for the harness to insure I have the correct wires going to the perspective injectors, and I did not accidentally swap the two wires!
There is a ground wire wrapped around the wires and I reinstalled the tin foil, around the wires as they were before I started. I have good power running through the plug, same readings on all four plugs now.
