I loaded Custom OS 0203003 into my 2003 z06. The car starts and then dies. I retraced all my steps to make sure that I performed than correctly. I checked the VATS (theft) settings and they all seemed to be ok. I did a comparison of files and the only things that were different were the values changed per page 7 of the install manual. I performed a search I'm not getting anything that I can use. Any help would be appreciated.
