Preheat oven to 350°F. Grease standard loaf pan with cooking spray or butter.
In a mixing bowl, combine the eggs, oil, pumpkin puree, and sugar. Using a whisk or electric mixer, beat until smooth.
In a large bowl, whisk together the flour, pudding mix, baking soda, cinnamon, and salt.
Pour the liquid mixture into the dry ingredients and gently stir to combine.
Pour the batter into the prepared pan and place in preheated oven. Bake for approximately 1 hour, or until a toothpick inserted in the center comes out clean.
Let cool for at least 30 minutes before slicing. Serve warm or at room temperature.
