Default Z06 #4 Replica electrical issues- help!

Just got my wife's track-street car ready for its first test drive. Ran great everything worked well got gas it restarted fine. Pulling into my driveway the service fuel system came on as well as the ABS light and tire monitor light and the fuel gauge stopped working. Ran great at the time, I shut it off and restarted it and no dash power but ran fine. Shut it off again and it would not restart the dash was dead. I could hear a clicking noise in the right front. I tried using the key fob to lock or unlock and it did nothing. It has a new battery, new remote battery, new LS7, basically the car was rebuilt from a dedicated track car from years ago. Any ideas? I will try to scan it next but thought I heard of this issue before for with the C6.

If you try to scan the car but cannot connect to ANY module it may be a CANN bus issue especially with no start !!

I was planning to try and scan it tomorrow I have a feeling it won't see the modules. Can you elaborate on a Cann buss issue, is it a fuse- location? I hear clicking noises when trying to start and stop near where the ECM is located.

This Corvette uses the older GM LAN network …basically how all the cars modules communicate with each other…it is not a fuse !!…video below to explain it better !!

Thanks, great video it sure helps to explain how the network can be affected by many modules, wires, sensors and more.
