1994 Dodge Dakota Motor not starting

Engine Mechanical problem
1994 Dodge Dakota V8 Four Wheel Drive Automatic

I have a 94 Dodge Dakota pickup (8 CYLINDER). When I turn the key to start the vehicle there is a click but the starting motor does not run. I need to turn the key on and off numerous times before the starting motor runs and starts the truck. Sometimes the vehicle will start the first time while at other times it requires numerous attempts to get it going. There is no rhyme nor reason to the number of attempts required to get the motor going. Any thoughts.
