Buddy of mine has a 04 6.0 truck has a miss and hooked up computer said injectors 1,5,&7 were spratically firing replaced them and the same problem persists any insight and help from u guys would be helpful

 

Did you check the wiring harness to the injectors? I would go over harness very carefully. I would also look at the ficm.

 

Looked ok and computer didn't show any interrupted power or short to grounds

 

A weak FICM will often throw codes for one bank of injectors, if suddenly you have multiple injectors on the same bank not firing properly then the most likely cause is the FICM, test the FICM as described in the "Sticky" section at top of the 6.0 page., they can be repaired for a lot less then new and they will even be a lot more reliable in the future compared to new.
