I bought the 64 that had been sitting for at least 10 months, but the owner said that it ran strong. When I went to check the car out it wouldn’t start and after messing with it for awhile I determined that the coil was bad. When I went to pick the car up I brought a new coil and the car started right up. I let it warm up for a few minutes before leaving to bring it home. It ran ok to the gas station down the road needed to give some gas to make it to my house. Again it started just fine but just a little ways from the gas station it started misfiring and hesitating until it just stopped and wouldn’t start again. So I had to tow it home. I have changed the spark plugs and wires and made sure the gap was correct but no start. When I do try to start it for a second it sounds like it wants to turn over then I hear a scratching metal sound after that the starter sound like it want to engage but nothing happen. So I’m going to check the coil but after that I’m stuck any thoughts? Knowing when I bought it I was going to rebuild the engine anyways I just didn't want to do it this soon.
