Thomas Spagnoli: workshop approach for Yamaha R1 2007 fuel pump relay replaced and fault returns next day

Before buying anything for Yamaha R1 2007 fuel pump relay replaced and fault returns next day, I would build a small test path. The cheapest repair is often the one where you do not replace a good part.

1. Define the condition: cold, hot, idle, load, rain, bumps, full lock, after refuel, or after charging.
2. Test the basics first: battery, grounds, fuel quality, connectors, vacuum leaks, air filter and recent work.
3. If intermittent, move the loom gently while monitoring the symptom. Do not pull hard; you are looking for clues, not creating new faults.
4. Replace parts only when a measurement or repeatable test points to them.

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

Small update from my side: I found one suspect connector and I am cleaning it before touching anything more expensive. I will post the exact result, even if the answer ends up being embarrassingly simple.
