west central ohio | I see that you said that injectors were done about 1500 hrs ago.. But what we would do when they just crank is give them a small hit of either, and see if they take off. If the injectors o-rings are slightly leaking, it will cause this condition, and the either will spin the HP oil pump enough to over come the leaks. Next, I would check the HP oil regulator (IPR). You need over 700psi to fire off the injectors at start up. The wiring to this solenoid is known to fail/ break right at the solenoid. Others have mentioned that ECM power and ground are very important. In the truck application the FICM was fused separately in the battery box. IDK how your machine is set up, but I would check the easy stuff first (FICM/ECM fuses) good luck.
