Preheat oven to 350 degrees F. Grease two 9 x 5 inch loaf pans and set aside.

In a medium bowl, combine flour, pumpkin pie spice, baking powder, baking soda and salt. In a separate larger bowl mix pumpkin, brown sugar, juice, eggs, oil and vanilla. Stir in flour mixture and 3/4 cup of the pecans.

Spoon batter evenly into each of the loaf pans. Sprinkle remaining nuts over the top of each loaf.

Bake for 60 to 70 minutes or until a toothpick inserted in center comes out clean. Cool in pans on wire rack for 10 minutes. Remove to wire rack to cool completely.
