My brother recently bought an 03 1 ton. The engine I believe has some valve issues. He blught an 05 engine and he wants to know if their would be any reason that it wouldn't work(programing issues due to the change in the nozzle spray pattern and the dish on the piston). He just wants to make sure before he changes it out and then finds out that it won't work. Thanks for any help.

 

The 05 didn't come with a computer and fuel system?

I think hrd have to use the 05 computr and fuel system

 

The 05 did not come out of a vehicle I think he said that it was straight from cummins.

 

I want to know if the 05 ECM will work on the 03 truck! Sorry I have nothing of value to add to this discussion. LOL.
