I decided to remove skip shift today on my 2002 Z06. I read the PCM and the read went to 4kb and stopped so I hit stop and tried again and it worked so I disabled skip shift and registered my pcm. I reflashed the pcm with the changed tune and that went perfect and I went to start it and it just cranked. I realised that the fuel pump relay was turning on and off rapidly and there were all sorts of warnings on the driver information center. I tried to reconnect and put the original tune in it, but it wouldn't connect no matter what I did, I couldn't even scan. I tried pulling the battery cable for about 10-15 minutes and that didn't help. I'm lost and want to drive my new car so bad. Any help will be greatly appreciated.
