I got a 2007 Cummins was driving fine never had a problem let it sit for about a month an now it has no power won’t start only thing I have found that works is the power seat an break lights when hitting the brake headlight won’t turn on the gauges read like it’s running even when the key is out hooked a scanner up an don’t have power there things thanks for any help

 

That’s how the gauges read with the key out of the truck

 

YOOO any follow up to this?
