How old are your batteries? If they are good, check the under valve harness make sure its still connected right, and then test it for continuity. If it tests fine you have two problems left. Take off the EDGE programmer and see if it clears the codes. The last two things two check are the FICM (fuel Injection Control Module) and or injectors. But I don't know the codes that were thrown. Where do you live? Well if your near this shop give them a call J & H Diesel in Mississippi I can't vouch for their quality and service but if they help you and do you right let me know. I'm working on a data base for reputable diesel shops.
