08 6.4 problem
Ok, im pulling my hair out About a month ago I removed the engine on an 08 6.4 for rebuild, truck drove in shop, rebuilt engine and installed. Hooked everything back up the way it was and now has a security issue. Truck will not turn over or power up fuel pump. If I supply 12 volts to the male end of the wire by the right battery box truck will turn over. Security light is flashing fast and truck will not comunicate with my modis or a ford scanner. Tried the batter unhook ,key on rehook, also checked power to pats in kick panel. Running out of ideas, even had a guy come over from the ford garage and he couldnt comunicate with it either. Please help, any ideas are greatly apreciated!
