So I go outside in the morning to turn on my car and nothing. The security Light goes on. I try to disconnect the batt and remove the ecm fuse. I put it back on and nothing. I hook up the scan tool and there is a code it U1000. So I use the tune tool to disable my vats and upload the tune to the ecm and still nothing. Is there anything I missed out on? Or any other trick out there? Guidance would be really appreciated thanks!!!
