I have a 2016 Nissan NV3500 with the 5.6L V8.
The vehicle started sluggishly once, then died, acting like it got no gas when the pedal was held down.
Replaced the battery. Battery is hot, the starter turns over vigorously - but nothing happens.
Fuel pump doesn't hum when the key is turned.
I see voltage to the coils.
Disconnecting the intake and spraying starter fluid in, trying to crank - nothing.
ODB2 connects, confirms power, then hangs forever - cannot communicate.
I have tested every fuse five times - three by physically unplugging and inspecting, swapping them around. Twice with a voltage tester.
I have replaced the crank position sensor.
I have confirmed the wiring harness to the ECM is snug and locked in place.
All I can figure at this point is that the ECM is bad or some wiring has gone bad elsewhere.
Any ideas?

Never "guess" ECM. Automotive issues are almost never caused by "computer failure".
I would lean towards some kind engine control power issue for whatever reason. It is possible one of the large fuses got blown when the battery was replaced, or during when it was bad. I respect that you've "tested" them, but I still lean towards that being a key possible cause of your concern.
Check for fuel pressure at the engine - then you'll know if it's related to that.
