Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9x5-inch loaf pan.
Mix Wet Ingredients: In a large bowl, whisk together the pumpkin puree, sugar, eggs, and vegetable oil until smooth and well combined.
Combine Dry Ingredients: In a separate bowl, sift together the flour, cinnamon, baking powder, baking soda, and salt.
Combine Wet and Dry Ingredients: Gradually add the dry ingredients to the pumpkin mixture, stirring until just combined.
Add Chocolate and Pecans: Fold in the chocolate chips and chopped pecans, being careful not to over-mix.
Pour the Batter: Pour the batter into the prepared loaf pan, and smooth the top with a spatula.
Bake the Bread: Bake for 65-70 minutes or until a toothpick inserted into the center comes out clean. If the top is browning too quickly, you can cover it loosely with aluminum foil.
Cool the Bread: Remove the bread from the oven and let it cool in the pan for about 10 minutes. Then, transfer the bread to a wire rack to cool completely.
Slice and Serve: Once the bread has cooled, slice it into 10 pieces and serve.
