Welcome to 2CarPros.
Both codes relate to the same component. Under normal conditions, the heated oxygen sensor 2 is not used for engine control operation. With that in mind, I feel there is a different issue. I attached three pictures for you to help locate the sensor in question. I added them in case you want to replace it.
There is a diagnostic flow chart that correlates with both codes, but it is extensive and requires a specific type of scanner. Again, I don't think that is causing the no start, but I have been wrong before.
Another thing that can cause these codes is a engine vacuum leak. Since the engine isn't running, you will need to check to see if any vacuum hoses are disconnected or damaged. Also, a faulty fuel injector or fuel pressure which is out of spec can cause it. I realize you hear it run, but did you check to confirm the pressure is within the manufacturer's specs? If you smell gas, a faulty fuel pressure regulator could be allowing too much pressure to build and flooding the engine.
Do me a favor. This is an easy check for the fuel pressure issues. Remove the fuel pump fuse and see if it starts. If it doesn't, with the fuse out, see if it starts for a couple seconds with starting fluid and let me know the results. See picture 4 for fuse location.
Also, before this became an issue, was the engine running normally? Did you notice any power loss, rough running or idle, or anything else you could tell me?
If you can think of anything, let me know. Also, try the fuel test.
I will watch for your reply.
