Recently we found out that the camshaft sensor in our 2000 Daewoo Leganza needs replaced. We have not gotten it fixed yet & the other night after driving it, it has not been able too start or even turn over since. Is the engine blown up? Or could there be some other problem? It had been driven hard that night, At about 90mph for ignorant reasons, But I just need too find out what needs fixed.. If you have any ideas PLEASE let me know!
