A friend of mine bought a used hypertech max energy programmer and tried using it on his truck but it seems that it has been used before and the previous owner didnt tune back to stock. The truck is a 99 ram with 5.2 magnum. When trying to use the programmer it said it was returning back to stock settings but then said the connection was interrupted and said to disconnect. While trying to program, the dash said "no bus" where the miles would be. It will crank over but wont start. What to do? Any ideas?
