I have an 06 6.0 f350. I thought I had made it bulletproof. And now my truck doesn't wanna run. I put two new batteries in tonight. it fired right up idled fine for a couple minutes. Then started to sound like an old 7.3 and the died. my diagnostics reads my OBD 2 is incomplete? Had a fuel issue. dropped my tank cleaned it changed filters... what could be my problem. besides its a 6.0

 

Welcome to FTE.
Can you list all the work that has been done
and it it was run after each step?

Also going to need to know things likeFICM power and
the FICM MAIN power,

diagnostics reads my OBD 2 is incomplete tends to mean that the
onboard tests have not finished yet and more start cycles are needed.

Post that info back to us and we will see what we can come up with.

Do a bubble test. There are video on you tube showing how to do it.
