I've installed many plugins in my .vimrc. If I removed the .vimrc, the ctrl-p/ctrl-n will do the completion work.(ref: :help completion(). How to check the key mapping conflict of vim plugins? How to re-map the original function.

My sample text is t.cpp in insert mode as: This T<-- press ctrl-p here, it failed, but ctrl-x,ctrl-p will show This

Here are vi commands and its result:

:verbose imap <c-p>  # No mapping found
:unmap <c-p>         # E31: No such mapping

After step by step comment out plugin, I found the major problem is caused by YouCompleteMe plugin, it works again when I comment out YouCompleteMe.

But, why this plugin can remove the ctrl-p original function without map? Is it possible to restore the original ctrl-p function and install the YouCompleteMe plugin?

For starters, :verbose imap <c-p> (similarly for <c-n>) to check what is redefining it. - Amadan

You can remove mappings using unmap command. Use

:unmap <c-p>

Then check to make sure there are no mappings using

:verbose imap <c-p>

If vim returns

No mapping found

You're good to go
