Hey All, so I know this isn't the right Forum to be asking my question on but I haven't gotten any help on other dedicated Truck Forums (dinks..) and with any internet research on my issues. Since sledders are awesome I thought I'd try reaching out to fellow duramax owners:
I bought a used 2007 classic duramax back in April 2019 with a bag glow plug (#5 if I recall) and check engine code (due to the glow plug, I scanned & confirmed it was the only code). I drove the truck most of the summer with it like this since it didn't bother me and no cold starts needed for the summers in Alberta. The coil light would on occasion be lit telling me to wait before cranking over the engine, which I did. I figured the coil light was coming on during the summer temps largely due to the bag glow plug.
I replaced the bad glow plug in September 2019. After replacing I cleared my CEL and it never did come back (voila, problem fixed!), but I also noticed that the coil light was no longer showing up when going to start the truck. It is now December and we are getting temps around -15 degree C in the mornings and I STILL am not seeing the glow plug light show up?? Most people said they start seeing it right around the freezing mark, even if it's only for a split second. I will wait until my CEL light goes away to crank the truck over since I am afraid to star tit too early and being doing damage. Is it possible that there is a fuse or relay that went bad for the glow plugs? The truck doesn't have any issues starting no rough starts or cranks seems like pretty healthy/strong cranking in -15 even when not plugged in.
A few more items probably worth mentioning, I have a PPE Xcelerator Standard Tuner (set at stage 2 90hp) that I tuned the truck with and check my codes with. Has an AFE air intake, MBRP exhaust. Also when I put my new tires on in the fall I re-calibrated my tire size and 1 week after doing so I got a DTC 2610 code (something about engine timer) looked it up seemed to be no big deal, so I cleared it and it has never come back since.
