Sometimes a starter motor and solenoid can stop working with no warning at all; brushes or contacts just wear out. You need to check for voltage at the starter motor terminal. If your car is like my 1991, there are two heavy positive cables connected to the battery; one for the starter and another for everything else. Be sure this cable isn't corroded at the battery post. The corrosion can happen under the red insulation and isn't always visible. The starter motor terminal can also become corroded. Using a simple voltmeter can isolate your problem. Does your vehicle have an alarm system?
