Moved to the 6.0L Power Stroke Diesel forum.

Welcome to FTE lildaryl. I've moved your thread to the correct engine specific forum to enable you to get better assistance with your issue. These folks are great and will help get you squared away.

 

Hows the batterys and alternator

I read a post from Cheeit that said the PCM will reset itself if voltage drops below 9.5 volts

Also check the FICM voltage needs to be 48 volts per tech folder

and scan for ICP it needs 500psi to start

and better yet go thru this

Thanks For YOUR Quick Response, I see some Good Options to try. I know a little,Where is the location of ICP Module or PCM. This Might be Helpful On Another Bus I was told need Injectors on the even side and it is still rough Idiling an Missing, Acceleration only about 50 mph. lildaryl

 

It would help to know the model years of the vehicles in question. Some components were moved around in the early years.
