Thomas Spagnoli: workshop approach for Yamaha Fazer 1000 pump prime normal but secondary injector rail has no pressure

Before buying anything for Yamaha Fazer 1000 pump prime normal but secondary injector rail has no pressure, I would build a small test path. The cheapest repair is often the one where you do not replace a good part.

1. Start with model, year, mileage, engine type, recent work and the exact symptom.
2. Separate opinion from measurement: voltage, pressure, compression, plug condition, code history and visual evidence.
3. Make a small checklist and tick it off in order. It is slower for five minutes and faster for the whole repair.
4. When in doubt, return the machine to a known baseline before tuning or modifying.

The best next step is the one that can prove something. A test that only creates another guess is just a more expensive guess.

This is also the kind of method I teach in the free Motorcycle Mechanics Course here on the platform: observe, measure, confirm, repair, then test again. It is much easier to solve Yamaha Fazer 1000 pump prime normal but secondary injector rail has no pressure when the process is clear.

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

I have enough to work with now. No heroic parts cannon today, just tests, notes, and hopefully fewer dramatic noises. I like that this turned into a checklist instead of a guessing contest.
