Mix sugar, oil and eggs until thoroughly blended. Sift together flour, soda, salt and cinnamon. Add to sugar mixture, beating until smooth. Stir in carrots, coconut and pecans. Pour into a greased 8-inch round or square pan. Bake for 50-55 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool completely in the pan before removing it.
