Hi cary bear, I splitted your post on a different topic so you can get personalized advice on your case.
Nap resistance is a toddler thing. In fact they will resist ANYTHING they can as their toddlerhood lasts
so all you can do is provide as much oportunities for sleep as you can, but not get into a power struggle cause you're likely to loose that battle LOL.
MAny moms here have found success with quiet time, that is, you provide a reasonable wind down routine (books, bye bye to toys and stuff in the house/street, songs, whatever) and pop him into his crib/bed. You let him know it's naptime for everyone in the house but and he can go to sleep whenever he wants, the only thing he needs to do is to stay quiet in his room for a while. LEave him with a couple of stuffed animals, soothing music, a couple of books and a blanket on the floor (in case he decides to jump out of bed). This leaves him options to do as he wants just not escalate and understand this moments as his quiet time.
If you try this and after a while he's still trashing around his room, only go in when he's getting too loud and remind him to go back to bed or stay quiet. He'll eventually go to sleep if he's tired enough.
HTH and good luck!
