uhhhhh,...... it wont run....lmao.....dude, i think alot of what COULD go wrong, may not ever know till you tear it apart..maybe hearing a rattle/clanging,deep inside, no compression, locked up....you have very low miles and a s9. you SHOULD be good with your motor...on my zx, i have heard noises, get nervous/pissed over it, but then it was nothing.... check your compression first........dont pull your own nuts on yourself....lmao...
