The starter on the Nova has starting acting funny. When it's cool it will start easily. When it heats up it will not crank and the solenoid doesn't click. It will jump with a srewdriver which makes me question if this is just heatsoak into starter. This developed all of a sudden. The car we rewired last year with a painless kit and I'm wondering if it starts with screwdriver would it more than likely be from key to starter rather than a starter issue. Any insight would be appreciated. Thanks.
