I have a 05 Chevy trailblazer ext v6 and I'm having a hard time finding out what's wrong with it. It all started when I went to town and all the sudden the oil pressure light came on. The oil pressure was all the way up. As I was slowing down to pull over it just suddenly died. And its hasn't started since then. I have got a new battery and alternator cuz they went out. And I had the starter checked and ot was good. When you turn the key to start it goes like a quarter turn and then stops like something is not letting it move. And it does it every time u turn the key. I dont have the funds to have it towed again to a shop just to have it looked at. And also I have hooked up a scanner and it isn't reading any codes at all. All the lights and everything like that's works when u turn the key. It must dont want to start. Can someone plz help me figure this out. It's my baby I've only had it for like a yr and half..
