I am trying to figure out how to tell the two apart and what is the actual difference?
My 97 Ram 1500 was originally a 5.2 but has been swapped to a 5.9. The 5.2 pcm is still in it but im not sure which injectors are in it. Reason I need to know is i'm sure I have at least one with a slow leak while its parked causing a mild flooded condition on start up after it sits for a little while.

 

I was under the impression that the 5.2 and 5.9 use the same injector.
