Engine/Transmission (1998.5 - 2002) Crank but no start

[Phennick]

Good morning gentlemen, firstly my rig. 2001 Dodge 3500 with 5.9L H/O NV5600. Bully Dog Super B turbo, AFE stage 2 intake, raptor high flow 100GPM rail mounted fuel pump, Edge Drag comp box, and 100HP Edge Jammer injectors. I have recently replaced the clutch, clutch pedal mount (which means I pulled the steering collum) and installed the injectors. All of this was done at the same time. I have since driven maybe 400 miles on the truck with no issues. 1 week ago I drove the truck around for about 1 hour in city without shutting it off with no issues. 2 days ago I went out to drive the truck and it will crank with sometimes starting for maybe 1 second, but will not run. I have verified the fuel pump is running and providing fuel up to the fuel injection pump. Checked all fuses. Have good air flow. At this point I'm at a loss for what could be causing the issue. I would appreciate any assistance with this.

P1693 is a companion code and is set anytime another code is set, so looks like something is wrong with the TPS circuit.

Start with Blue Chip Diesel VP-44 Diagnostics

Even without a TPS it should idle.
