Combine the graham cracker crumbs, melted butter, and sugar. Mix together, then press firmly into a 9 inch deep dish pie plate and bake at 325° F for 10 minutes.
While the crust is baking, toast the coconut by spreading 1/3 cup of it out on a rimmed baking sheet. Bake at 325°F for 4-6 minutes, stirring once. Set aside to cool.
In a large mixing bowl, combine the sweetened condensed milk and lemon juice and mix well. Stir in the drained pineapple, oranges, and pecans, reserving 1-2 tablespoons of pecans. Fold in the Cool Whip and the untoasted coconut.
Spoon the filling into the prepared pie crust; sprinkle with toasted coconut and reserved pecans.
Refrigerate for at least 4 hours to set, then garnish with marashino cherries & enjoy!
