Thomas Spagnoli: workshop approach for Honda Hornet 600 direct battery power makes pump run but engine still no start

With Honda Hornet 600 direct battery power makes pump run but engine still no start, the useful question is not 'what part is famous for this?' but 'which system stopped doing its job, and under what condition?'

If you report back, include the measured values, not only whether it felt better. Numbers make the thread useful for the next rider too.

Good point about documenting the baseline. I took photos before touching anything, which may be my most professional move this week. I like that this turned into a checklist instead of a guessing contest.
