I have an 08 2500 6.6 the truck has been through quite a lot but this is my questions with a lil history first. Truck sat for a year in a garage. Got it back and have had problem after problem. Had the dpf delete done. It ran great for 3 days. The batteries were bad so I replaced them. Now the truck will not crank with key and my scanner will not communicate. Scanner is good and reads other vehicles. I have a solus. I really dont know symptoms of a bad ecm. All fuses are good. Can someone shoot some advice or suggestions my way. Thanks in advance
