Is it an injector

[04fording]

Helping a buddy out with his truck its an 03 350 6.0 psd. Its starting running rough about a week ago. I scanned it came back with a bunch of codes didn't write them down. They were #5 injector chk high, #5 balance, #4 balance, multiple/random misfire, and another code with #5 can't remember. The buzz test on it was successful(pass). He has 2 new injectors for it but don't want to rip into it and that not fix it any suggestions?

I would start doing tests on the head gaskets next.

Bad batteries, ficm...... You need to do the ficm check procedure, and get a monitor on that truck.

Head gaskets good did that already and the ficm is good as well.

What is ficm good. voltages above 45, right? Just having good voltage does not mean the logic side of the ficm is ok. Something is killing the injectors. Fuel pressure, hpop pressure.........?

And it doesnt eat up coolant only goes through a little oil. The truck has 286***k on it he just wants it running good so he can trade it in on a 2012.
