Grease and flour two 9 x 5 loaf pans (or spray with Baker's Joy). Set aside.
Preheat oven to 350º.
In a large mixing bowl, combine sugar and oil. Add eggs and beat well. Add zucchini, walnuts, pineapple, coconut, vanilla, and cinnamon and mix to combine.
In another bowl, whisk together soda, salt, baking powder, and flour. Stir into zucchini mixture with a rubber spatula or wooden spoon just until combined. Do not overmix.
Pour into two prepared pans. Bake for 50 minutes-1 hour, 25 minutes (time will vary depending on your pans and oven). Test with a toothpick. Loaves are done when a toothpick inserted in the center of each loaf comes out clean.
