O.K. This is my first post so here goes. I have a 68 coupe with a 302 2V w/ a C4 auto trans. First the teeth on the starter were all chipped. So I replaced the starter and the starter solenoid at the same time. I started the car a couple of times and it sounded like the start was not dis-engaging completely. So I used some thick washers as spacers on the starter and re-installed it. When I started the car it sounded like the starter was still hitting the flywheel, but worse. So I turned the key off, but the engine kept running. So I went and pulled the negative lead off the battery to kill the car. I messed with the key and then tried to hook up the battery again, but when I went to hook up the lead it sparked and the engine tried to run. So I replaced the new starter solenoid with the original one, but when I tried to start the car it wouldn't even make a noise. Nothing at all, not even the starter. I pulled the starter off and had it tested and it tested fine. I replaced the starter solenoid with another new one and still nothing. No noise at all when I try to start it. My battery has 12.80 volts and the lights, radio, and gauges all come on and register. I have replaced the ignition switch and the key\ tumbler with new ones from O'Reilly. I also replaced the Voltage regulator, and the alternator is about 2 months old. I have no clue what is going wrong and am at the end of my knowledge. I am not sure if something might have blown when the spark happened. I verified all of the fuses are good and none blown. Please help.
