Hey Fellas; Got a 94 Z28 project car for real cheap and am having trouble starting it.
It has 117,000 miles and previous maintenance is unknown.

Had to replace the Bendix drive on the starter to get to this point; but when trying to start, the motor will crank and then once you let go of the key the motor will kick back.

Hopefully it hasn't destroyed a rod or valve yet, but what exactly would be the cause or things I can check.

Would the Optispark cause this condition?
Or does it looked like it jumped timing?

Appreciate any help.

I'm trying to check all I can before replacing it since it's not the cheapest part to replace.
Thanks for the reply.
