Cranks but won’t start - 2019 2500 Cummins

The build sheet says it has the 68RFE

I’m not in front of the truck at the moment to verify position of the trans dipstick but will take a look when I can.
 
Last I looked the duration tables are the same SO vs HO, which tells me the injector is the same... but maybe there is a different spray pattern for the SO piston vs the HO piston?
The body's will be the same im sure the nozzles would be the difference in P/N…. Id be interested to know the actual differences instead of speculations though

I'd like to know as well.

Whatever the differences are they flow the same.
 
Where'd that come from? I looked around a little for the flow rates, but didn't have much more time to spend after I got all the PN's collected.

From looking at the stock duration tables, they are identical between SO and HO. Even the C&C uses the same duration table.
 
Since picking the truck up I’ve driven about 600 miles hauling 10,000 lbs and just got a P2459 code. Looks like it’s related to the regen process. This is the first time I’ve even seen the diesel particulate filter above 0

I've started monitoring it and regen took 6 miles and then after 66 miles, it regened again and took 28 miles. Hilly terrain.
