Then about 2 miles later my dash lite up like a Christmas tree!!!!! Truck strarted running super rough and when I parked it and tried to start it up no go..... Would crank then battery would die. I charged up battery and replaced alternator..... Still wont start..... I was able to get it started by holding down has petal but as soon as I let it go truck dies and battery dies as well..... I really need some advice for this is my work truck..... Any help ?????????
