I have a 99 Dodge Ram 1500 4x4 with the 5.9 liter in it. It was driving just fine one day I got home, went back out to drive it and it wouldn’t start. I did happen to notice the fuel pump didn’t kick on when I turned over the key and the no bus code popped up on the cluster where the mileage is. The guy I got the truck off of said he swapped the 318 with the 360 but never changed the computer but the truck ran and drove. Would I possibly need a new computer?
