My buddies lifted and bombed 2500 Cummins had the same problem. Turned out to be the spark plugs. Check those.

Are you having trouble just today? Lines could be frozen

Did you check the lift pump? A 6.5 will start on a very dirty fuel filter. There is module attached to the intake manifold that can cause starting/stalling issues when it starts to fail. GM, in their infinite wisdom, decided placing a heat sensitive part in a hot location was not a bad idea. Common fix is to buy a new module, lengthen the wiring harness, and mount the new one behind the head light housing.
I think you are talking about the PMD (pump mounted driver) sometimes called a FSD . I am pretty sure that this is his problem. Pretty easy to change it out and relocate it like you said.

How cold is it up there?
I know Diesels are harder to start in the cold. Did you try plugging in the engine block heater and trying again later?

From your post, I agree that the fuel filter is the first thing you check out/replace.
A couple of yrs ago, I started up my Duramax one morning to let it warm up. Outside temp was in the 30's, but not freezing.
It idled for about a minute, then just died, unable to restart.
Towed it in to the dealer, and they diagnosed clogged fuel filter.
Service interval for replacing the fuel filter was every 15k miles, and mine was right at the 15k mark.
Diesel mechanics are in general agreement that you need to be replacing your filter more frequently, like every 8-10k miles.

He sounds like the typical Dodge owner.

Changed the fuel filter. Still no luck.

Make sure the air filter is clean.
Obviously, make sure the fuel level is decent. Fuel gauges go bad.
Don't use starting fluid, but you can use WD-40.

Is the fuel in the fuel tanks diesel?
Seriously, check your ground strap to the frame from the block. It happens.

Did that on my brother's 6.5 TD Tahoe when it stated having those issues and they cleared right up. Also removed the exhaust and straight piped it all the way back.

I've used starter fluid, but you have to be careful. Had to spray some once when I ran out of fuel. Took 2hrs to get it running and the batteries were hurting pretty bad after all of that cranking, so I was all I had
OP, search "6.5 no start". You should be able to find all possibilities there

Yeah, you can use starting fluid, but it's a gamble on a diesel.

I had a 2002 F-250 w/powerstroke. At about 120K miles the engine would shut off at low rpm and at idle. It was very hesitant to restart after it died. Cam shaft sensor replacement fixed it.

Sorry, I can't help you beyond this point. As others have said, check the lift pump.

Yeah
