So I just bought an 88 comaro with a Chevy 350, obviously not the original motor, the car was running just fine. I drove it from a Bronx to Hackensack. Now when I go to start it it doesn’t crank it just makes the noise of an electric motor humming. The battery is charged but when I crawled underneath I found that the noise was definitely not coming from the starter. Btw I’m a little new to auto mechanics and this car is like a first project
