Cummins won't Run

I have 99 dodge cummins. I drove the truck all day long. I stalled the truck in front of a store, walked inside to buy a few things, walked towards my truck, tried to start the engine but nothing. The truck starts but won't run. I have replaced the ECM, PCM, Injection Pump, All 6 Injectors, Crank Sensor, Cam Sensor, I opened the front cover to check the timing and everything is good. Its got good fuel pressure, (15 PSI) Good clean fuel. My Genisys gives me no codes.
