Reasons Your Vehicle Did Not Pass Tech Inspection?

I've never been turned away. But I have had them tell me "what they'd like to see" next time. :D I try to comply. For years, my tech inspector would ask "any changes"? I'd say nope - and on I'd go without lifting the hood. If I said yes, they ask "what", and sometimes it was something they wanted to see, most times they'd say ok.
