Diagnostic Process

Just a thought, I think a section about the "Diagnostic Process" or "Diagnostic Routines" would be awesome.

Seeing what other people do to diagnose problems may help everybody become more efficient.

I'll second this. Seeing other's ideas and structure for diagnosing would be interesting.

I like this idea. I often wonder if there is a better way to go about diagnosing something. Like when you can rule out several possibilities with one test up front.
I imagine it to be something like the topic being No Start and then they could say in general how they would proceed. Or misfire, lean condition, low power, AC performance, etc.
