That is interesting that you had a crank code and do not now and still does not start.

Here is a guide that will get us started:

Did you check for codes after you cranked the engine? Or did you replace the crank and clear the codes and because it cleared, we are assuming it is not still there? Sounds silly but we just need to make sure you checked again for codes after you tried to crank the engine.

Next we need to pull a spark plug out and make sure it is not fouled. If you had a no start issue and the crank was the issue then it may have soaked the plugs and they are now failed due to fuel soak. So you may have fixed the issue but still have a no start because your plugs are fouled.

I would suggest changing the plugs and retesting. Here is a guide that will help with this. Plus I attached the info below on how to change them.

Let me know if you have questions.

Okay. Has there been any history to this? You have Cam Crank Correlation codes for both cams on bank 1. That means it is either out of time or we have an issue with the cam actuators on that bank.

Have you had the timing chain or any other head work on that bank?
