It's the same starter that came on there. I replaced the Solenoid. I never really thought to check when I was doing the testing. The piston would fire, the flex plate spun so I assumed all was good. It very well could have been stuck in the engaged position then too. If I hit the terminal to only fire the piston, it returns ok. Just when it engages the flexplate and spins it does it get stuck. It's the only one I got, no spare
