Preheat oven to 350 degrees. Spray a 15 x 10 x 1 inch pan with non-stick cooking spray.
Combine the flour, baking soda, cinnamon, pumpkin pie spice, and the salt; set aside.
In a mixing bowl, beat together the pumpkin, sugar, and the oil. Add the eggs and mix well.
Add dry ingredients to the pumpkin mixture and beat until well blended.
Pour into the prepared pan. Bake for 25 to 30 minutes or until a toothpick inserted into the center comes out clean.
Cool completely
