Camaro trouble starting
So this all started when I did a top speed run. I hit 156 and then a check engine light came on and was flashing. I stopped the car plugged my cheap ass scanner in and nothing came up. Turned the car off and back on and ran fine. The next day I was driving and then it starting backfiring real bad. Plugged my scanner in and it said crank relay Circuit a. Something like that. I changed the crank replay Sensor and it still did the same thing. Checked a plug and found a broken spark plug in cylinder 7. Put one new plug in there ( it’s a tr6 I had laying around and I have stock plugs I’m the rest..... it’s only so I can get to work today.) it ran fine for awhile now after driving for a bit when I turn it off and back on it doesn’t want to crank up unless I give it gas. Had to get a friend to give me a jump. The crank sensor relay code is back up also. Any idea on what the problem could be?

Hope you didn't bend a rod or worse, spin a bearing... sorry not much help here. Take it to a good shop if you're stumped...
Good luck with your issue.

Does it crank at all (like battery) or does it crank but no start?

.
It runs fine till it warmed up I’m thinking. When I turn it off and try and turn it back on it doesn’t want to start. When I let it cool all the way off it cranks right back up. No codes.

You don't state what year your Camaro is, what state the battery is in, and it could be some what heat stroke to the starter but more likely a not tight crank position sensor, and you driving the crap out of it did not help obviously. I would say you should take it to a competent shop. No knocking etc is good.... And you don't state what mods are done prior to your run up to hit the limiter and what you have done for maintenance over the years....
