There could also be an issue with your ignition switch. Sometimes when they wear the ignition switch will not make contact and the starter will not engage. I suggest trying to jump across the solenoid contacts with a screwdriver. If the starter engages then the issue is in the wiring if not then the starter or solenoid probably needs replaced. Also while you are at the starter check the fusable links. One may be burnt and not allowing contact when you try to start the car.
