I have an 06' LBZ duramax. Heres my problem....the fuel filter needed to be changed so we changed them out. After bleeding the line I cranked the truck and it ran for maybe 5 sec. and then died. It would not crank after that even after we went through the whole process again. Now the message board on the dash isnt showing anything either not even the mileage. I have never had a problem like this with changing the filter, can anyone help?
