Did you unplug the injector plug and do the wiggle test on injector and FICM end?
Maybe just coincidence the GP is faulting on that cylinder. When is the last time you checked codes before the rough running started? That glow plug code may have been lurking for some time.
What is the output on your FICM and alternator?

Jiggle test? The connector seemed to be seated properly. I didn't remove it. I don't have the tool to remove it and didn't want to chance it breaking. I will check at the FICM end also. I figured if it was loose I would get more than one Cylinder fault. The GP fault did show up a few months ago...but went away. I didn't think about it again until you mentioned it.
