6 glow plug cycles?

13 degrees. Brand new batteries and starter spinning fast!
Is that to many cycles? Plugs going possibly?

Sure seems like a lot. I would bet a few have burnt out.

Thanks

Have you ever changed or tested them? If you don't know how the TM 9-2320-289-20 tech manual has a step-by-step on how to do it.

Do you have a multimeter and know how to use it?

And is the GP resistor pack still installed on the firewall?

Its at my buddies shop. Hopefully he can check it out..changing out leaky fuel return lines. Dang trucks!
