I was wondering what function evil mode ran when I pressed `:w` I
tried using `C-h k` and then I pressed `:w` but it only registered the
`:` I pressed and showed me information about `evil-ex` function
instead of showing me what function is run when I save the file using
`:w`.

That's enough info to point you in the right direction.
If you search evil's source for "evil-ex", I'll bet you can find it.

You can look at the value of `evil-ex-commands` to see what emacs
command is run for each ex command.

`evil-write`
see evil-maps.el for all ex commands

You've already got specific answers.

As a more general approach to quickly scratch unobvious places, you
could use (or abuse?) built-in [profiler](https://www.gnu.org/software
/emacs/manual/html_node/elisp/Profiling.html):

1. `profiler-start`
2. Run the `:w` command
3. `profiler-report`
4. `profiler-stop`

This will display a call tree, which should help you narrow down to
specific functions you can e.g. read or [debug](https://www.gnu.org/so
ftware/emacs/manual/html_node/elisp/Function-Debugging.html).
