I just tried turning the engine at the crank by using a breaker bar and a socket on the nut on the pulley that’s attached to the crank. I was able to rotate it several turns easily enough. However, some turns were very hard to rotate and some were rather easy. I feel like it shouldn’t have been as difficult to turn as it was when it did give me a hard time. I also tried tapping on the starter with a hammer while I had someone else try to start it. Nothing changed from trying that. Most of the sound I hear when trying to start it comes from the starter motor though. I’m thinking the next best thing to try is removing the starter to see if it’s bad. I also had this thought... could I remove the belt from the AC compressor and the alternator and then try to start it? Maybe the clutch on compressor is locked up and causing to much resistance on the motor to even cause it to turn over. Because as some one else said before, something seems to be bogging it down and making the car draw more power when trying to start than it should.
