Ok I just tested all 8 plugs via the black and green connectors at the GPCM. Each one checks out 100%. Which is a relief, my harness must be ok and the plugs themselves are ok. Must be the GPCM. Some monkey lost the pink piece on the green connector in the past

Looks like I had a two part problem.

I'm going through the same problem.have had a chance to look at it. I'm almost sure it's the controller.

The new truck did the same thing and I replaced the GPCM and
all was good and happy after that.

We'll I'm happy to report that I am glow plug code free for several days now. I replaced the GPCM and the remaining 2 codes have disappeared

So to sum it up I did have a compound problem. Thanks for the help everyone

P0671

I recently got a P0671 code. It's been approximately 5 years since I last changed my glow plugs and harnesses. Since it isn't too expensive, I am going to change them again. I'm on the fence as to weather or not to change the module too, just trying to save some money. Any thoughts or suggestions? Thanks
