2005 cummins motor in 2004 Truck?

I have a 2004 Dodge 2500 Cummins with a 2005 Cummins motor in it.
The manufactor date on the truck is 11-03, so I am pretty sure it is not the 2004.5.

I am running the 2004 ignition, wiring harness, Fuel resivoir, and ECU.

Do I need to change the injectors on the 2005 motor to 2004?
Also, is there any difference in the 2004 / 2005 injector pump?

When plugged into the cumpter the only code coming up is P0633.
Truck will turn over but will not start.

I want to make sure I am headed in the right direction?

Its a 2004 truck. Don't swap the injectors, different spray patterns.

The 2005 engine will run pretty decent but not exactly right. It should start fine if everything else is good.

The code you have is for a SKIM key and it may be the source of your problem.

Ther is no differenc ein the CP-3 between years, the only big difference is the injectors holes and piston bowl.
