I have an '88 LX 5.0 that has been running great since 88. Lately, however, I have been having intermittent starting problems. When I try to start the car, I can hear a grinding noise and the car will not start. If I keep trying I can eventually get the car to start and then everything is fine for the next few starts until the problem repeats itself. The Battery and cables are practically brand new. Think I might have a starter that is in need of replacement. Any thoughts. All help is appreciated.
