Hey guys Ive got a problem. Last week i posted my truck wouldnt crank. The interior lights dont work, Door locks, Dashlights takes 3 or 4 minutes to wome on, Gauges. We plugged the computer up says low bcm power. I dont remember code off top of my head. truck will not crank over at all will not even click. Head lights still work, radio fuel pump kicks on and off. Although my head lights work my daytime running lights. Doesnt My fog lights does not either. We switched and put another bcm on and still same codes. Have ran all wires. All good any ideas? Any input would be greatly apperciated. Thanks in advance.

yes have checked all wires> something makes me think it has to do with the trans in some sort of odd way bc this is the 2nd time it has done it and both times it was never taken out of park while running

any body have any ideas? I am starting to think IT is the tcm because the 2 times it has done it is when the truck has not been took out of park and just ran for a few minutes. then turned off. I am hating paying a $550 dollar truck payment and no truck to drive. any help would be greatly apperciated thanks in advance
