Need help... Hopefully you all can help me out never owned a deisle before. I have a 1998 Dodge Ram 3500 12v turbo power. This used to be a tow truck and the previous owner converted it to a daily driver. I have to jump start it every time you want to start it. Once the truck is to the starting position and cranks over which starts up fine. As soon as we release the key the truck dies. Replaced the entire ignition thinking that one of the pens off one of the recalls I saw on the form was the problem. This didn't fix the issue. Please help.
