Default 05 C6 Corvette won't start

press start and whole dash turns off except check engine light. Car doesn't crank over. Battery is good. Starter is good. I jumped the starter really and got motor to crank over. Seems the computer isnt sending spark or fuel. My column lock is broken, but it's been broken for months and I'm just having this no start issue now... So I don't think that's the issue. Any input would be great.

I'm not sure how you determined the starter to work. But I am wondering what the battery cables look like. And what I would look at are the cable contacts at the battery.
If you see any corrosion a little baking soda and water will clean that up.

Curious how you determined battery is good, did you have it load tested? The reason I ask is the symptoms you describe are the same as I and other's have experienced when a battery has gone bad or had lose/corroded cables. The computers in these cars are very sensitive and if the battery is bad or going bad, the starter will not engage, dash and other lights will go out for a second or two, you may even get some DIC warnings. Have had it happen a couple of times over the past 12 years; in both cases, battery showed fully charged, however when load tested, tested bad.

Std or automatic ? My 2005 6 speed did the same thing and it was the clutch switch. Computer does not see your clutch peddle depressed and will not start the car. You can install a new switch in 15 minutes.
