Preheat oven to 375°F.
In a food processor, combine the graham crackers, Crisco and water. Press mixture in the bottom of a nine-inch pie tin and bake for about 7 minutes. Remove the crust from the oven and reserve while you prepare the filling.
Combine the eggs, pumpkin, sugar, cinnamon, nutmeg and ginger in a bowl and pour the mixture into the reserved pie crust. Bake for 40 minutes, until a knife inserted near the center comes out clean.
