Glow Plug Question

Hello, I have an 04 F350 with Glow Plug errors on cylinder 2, 4 and 8. I have already replaced the harness on that side because the old one was gunked up pretty bad. Still have the same issue. Does this sound like a GPCM issue to ya'll?

AE pulled the following codes:
P0672 Cylinder 2 Glow Plug Circuit
P0674 Cylinder 4 Glow Plug Circuit
P0678 Cylinder 8 Glow Plug Circuit

Not having issues starting but it rarely gets into the 30's here in FL.

Thanks for the help,
Dave

These are pretty good about diagnosing the module. So I would have said the harness was bad. But since you've changed that, and I doubt that you've got 3 bad GP on one bank, then I would say the GPCM is next most likely.

I've replaced mine and it wasn't terrible expensive. I wanna say about $60, but it's been a couple of years.

Thanks for the speedy response Bill. You have been very helpful with many of my other repairs and you dont even know, lol. (Next, I'm going to try and figure out how to retro-fit some upfitters on my '04.)

I will research some testing techniques for the module and post back on here once completed. Originally, I figured it was the harness as well but such is life.

These forums are awfully helpful for us 6.0 owners so thanks!
