Ok so on my 87 GT, when I turn the key to start the car you can hear the starter whining like its spinning and not engaging the flywheel. The first time it did this I thought the starter was bad but it was still under warranty because I replaced it 3 months earlier so I went and swapped it and put the new one in. At first it started just fine but then it was doing the same thing. I thought it was autozone just giving me junk starters so I went and traded it in and put the new one in but it did the exact same thing, it started fine the first few times but now it's doing the same thing. What do you guys think? It started around the same time I did the 3G alternator upgrade also if that affects anything.
