That's the return value from the function, so Emacs will display it if
you say M-: (pulse-momentary-highlight-region 0 40) (which I assume you
have).  I.e., the message is from M-:, not from
`pulse-momentary-highlight-region'.

If the problem is that `pulse-momentary-highlight-region' doesn't pulse
in your configuration, but does pulse with "emacs -Q", then it sounds
like the problem is with your configuration somewhere.
