That is not the case here. He hasn't tried (or at least hasn't posted back results) what I recommended, which I based on a knowledge of how the system works and simple logic, and I'm a pretty good mechanic. At least half of all the "professional" mechanics I've ever met are not as good as I am at diagnosis. There are some on here better than I am, too...

There is a practice test online for ASE Master certification. I took it and passed all the sections except electronic diesel, and I came within 5 points of passing that one.

Done braggin' now...
