6.7 PB Start Question
I'm new to diesel ownership and have a 2019 6.7 with push button start. When I was in USAF, our diesel flightline vehicles required you to turn key on and wait for glow plug light to go out before starting engine. This usually happened on first crank of the day especially when its cold out. With my 6.7, I just get in mash button and it fires right up. What gives?

The system allows for glow plug warm up on cooler days. It will delay the crank and you’ll see a message saying something like “wait for start” or “starting...” . On most days, the plugs warm up so fast it’s practically instant

I spent the winter in Kirkwood, CA. High up in the mountains. I'd use remote start, but it seemed to be almost instantaneous from the time I pushed the button. Also, I've since found out I was letting it warm up to long. Per the manual (actually, someone here pointed it out, since I haven't gotten around reading the whole manual), a long warm up period isn't needed. But I still babied it until it got up to above 100 F Engine temp.
I saw it the "wait for start" a few times I didn't remote start it, but it was never more than a second or two. Some days temps in the single digits (F).

The computer knows how long to wait to start based on the temp. My truck is normally garaged at night and even when it was around 0° outside it was still about 45° in the garage. There was not much if any difference in starting time from when it is 70° outside. However, on a couple occasions when it was parked outside overnight and the temperature was below freezing and I hit the start button it took about three seconds before it actually turned the truck on.

Those flight line diesels most likely could run on JP-4, JP-8, desiel, or whatever for mission purposes.

Ugh. These glow plugs with short run time drive me bonkers in winter. I have mornings that are -35C to -40C. If I use the command start, the truck fires within a second and a god awful metal on metal noise is present. I started going out to the truck at that temp and cycling the glow plugs 3 times which when started, eliminated the metal on metal sound. The owners manual and dealership says that it is harmless but to me, metal on metal is not good. I wish the glow plugs stayed on a little longer when using the command start in those frigid conditions. The truck is plugged in every night too.

I dont like anything below 45 degrees actually. Where I live we may see single digits maybe twice a season. Luckily my truck stays in a garage!
