Naps or no naps!???

We are having a major issue in the household right now.... When Ella take a nap she fights sleep at night so much for hours and we do everything we know how to do.. take away toys, time out, threats of spanking... anything you can imagine. After preschool she is so sleepy and wants to take a nap and even when I let her she will only sleep like thirty minutes but then at night time watch out because Ella is on a rampage! She is hungry thirsty bored hot cold has to tinkle has a tummy ache feels like someone is blowing her hair.. it is really the AC.... so nap or no nap seems like no nap to me!
