Cranks, Sputters, No Start

Truck: 2015 Tradesmen, 4x4, 133k miles on the O. AEM stock tune, no W58 completed as of yet. (wish i did)
Problem: Cranks, no start
Symptoms: Truck started, drove 50 feet and than stalled with the ole TPS fault on the dash HMI. No start after.

Completed items: Battery is on charger when I troubleshoot. Fuel Filter changed when problem ocured. Always on time with PM schedule. Shell Rot. 5/40 used. Mobile 5w40 was used during the Rotella shortage of 2021. NO codes for anything relating to no start. I have my typical dirty intake swirl valve codes, along with a p0128 code that I cannot fix even tho T-stat is new. 5 gallons of new fuel added to tank.

Had my ED towed to my house a day ago since it would crank but no start. It sounds like its about to take off and fire, but never does. So its not just a crank, no start. Its a crank, almost start, no start.

I will post the AlphaOBD report, but keep in mind this was preformed with a non running engine that was only cranking. I noticed on one report, it claimed I had water in the fuel. This is why I added new fuel. Reports after claim no water. Never had any kind of light and the ECM (in alphaOBD) claims the truck has driven 0km lifetime with a water warning. So, not sure why thats there. I also noticed an alternator fault on the report. Never had any voltage or charging issues so not sure what to think here. Crank signal according to AlphaOBD is not dropping and is recognized. Fuel rail says its getting pressure on A-OBD and the lift pump turns on (going by ear) for 30 seconds, primes, and shuts off.


My gut tells me its the reluctor magnet. My heart wants it to be the alternator. Could the alternator issue of been masked by a battery that was strong enough to run all the glow plugs/injectors/pumps. I am fully prepared to drop this transmission and change the part in my cold wet driveway if thats what it will take. But I dont have the time or money to be a part changing monkey. I need a surgical diagnosis before my mitts get dirty. Single father with 3 children, full custody, and this is our only vehicle. Its my bread and butter and I need it NOW!

In the meantime, Im dropping 400 dollars a week on a rental car and skipping important bills along the way. My only option really...

I have a video of the truck cranking and sputtering, and I can provide any A-OBD reports needed. Attached is a report I pulled while I was cranking away hoping for a miracle.

My next step, i guess, is to remove the starter and use a bore scope to maybe try and see the tone ring. At least that will give me a solid path forward.

Any help is appreciated.

PS: The "alternator" fault... Is it faulted because its not being run/excited?
