I have 2005 f550 4x4 my battery light comes on and my truck shuts off . Until this happened everything worked as it should . Alternater was charging good . It did it 4 times randomly and battery light would go off after a bit the truck would start last time it did it my **** wouldn't tell my injectors to turn on. So I replaced ficm and now battery light is still on and truck won't start. If anyone has any ideas ples let me no thanks.
