wont start, electrical problem
 

hey guys, Im new here! Love the site! thought maybe someone could help me out with some problems im having. I have 95 6.5 with about 130,000 miles on it, truck runs great! still using the factory PMD and everything. Well a couple days ago i drove to work, about two hours later i went out to move it, turned the key, waited for the gp light to clear, tried to crank and failed. now the gp light will not come one and neither does the ses light. I have no power to the ecm or gp fuses. I cant connect a computer or anything either. Ive checked everything i know to check and haven't found anything wrong. I put a new gp controller on it and still nothing. please help!
