In medium bowl, stir together all-purpose flour, baking soda, pumpkin pie spice, baking powder and salt. In a separate bowl add pecans and raisins and mix with 1 tablespoon of the flour mixture.
In a large mixing bowl at medium speed, beat together butter and sugar until light and fluffy. Beat in eggs, canned pumpkin, orange juice and vanilla until well blended.
Add remaining dry mixture to pumpkin mixture and beat at low speed until thoroughly blended. Stir in reserved pecans and raisins.
Lightly grease a 9" x 5" x 3" loaf pan. Pour in batter.
Bake in pre-heated 350 F oven until lightly browned and a toothpick inserted in the center comes out clean, about 60 to 70 minutes.
Cool on wire rack for 10 minutes.
