My computer isn't able to get any readings

Hello, "no readings" or will not communicate? If it won't communicate with the engine's processor, it could be that there is a burned out fuse for the data link. Check there first. No cranking, however, also could mean dead battery or starter motor issue - or electrical power issue or even a major internal engine issue.
