Looks like you have a couple issues. Just looking at some of the C codes and a few of them are pointing to an internal failure of the Electronic Brake Control Module. Unfortunately the only fix for this is to replace it. I attached the info for this below.
However, this will not cause the engine to not start. So we need to find out if we have spark so, we need to pull a plug and hold it against the block and see if there is spark.

As for the other codes like the ECT circuit high, that would not prevent the start either.
So we just need to rule out the basics. Sounds like you ruled out the fuel with ether but we need to check spark and then check the compression and just make sure that is okay.

Let's start with this info. Thanks
