I pulled my motor to replace #8 piston and head. Put everything back in and I have no power to the truck cab at all! Jumped the starter, it cranks. So starter is grounded and pos is good connect...scratchin my head. Please help

 

Do you have power at the underhood distribution box/panel?

 

there may be a lot of reasons without being there I first would install a ground wire from the cylinder head and the fire wall. an extra ground never hurts. good luck you will have to back track what you pulled apart. I will keep an I on your progress and maybe help down the road.
