Thank you, I'm reviewing the checklist now. going to start working on it today. I also agree on the bats, I'm in the process of charging them while doing other things to the truck today.

thanks everyone.

 

Update: the other day I tested the FICM at Key on and had 48 volts, today I had a helper and after replacing both batteries, I tested while turning over and had only 20 volts so now I'm suspecting that it's confirmed FICM failure. I called FICM Fixer and he will rebuild next week.

Thanks everyone for the assistance. Will let you know if that solves this issue.

 

call ed and have him do the altas 40 tune at the same time money well spent.

 

Update, took FICM to FICMFixer.com and within the hour, the unit was fixed, installed today and the truck is running like a top. Thanks Texastech for the info and the help.
