If you mean to tell someone not to waste his/her time in doing something then the sentence you wrote is not correct , you rather say :
" Dont waste your time doing so and so "

ithink it is better to say(DONT DELAY TO DO SOMETHING) IF your main verb is delay
& if dely is a name for some one youcan say(DELY HASNT TIME TO DO SOMETING)
OR (DELY HAS NO TIME TO DO SOMETHING)
