Thomas Spagnoli: workshop approach for Suzuki DR650 fuel pump connector power disappears with tank installed

Before buying anything for Suzuki DR650 fuel pump connector power disappears with tank installed, I would build a small test path. The cheapest repair is often the one where you do not replace a good part.

1. Make the motorcycle mechanically healthy first: compression, valve clearance, plug, filter, fuel delivery, chain/CVT and brakes.
2. Choose changes that match the use case. City scooter, commuter, trail bike and highway bike need different compromises.
3. Confirm legal and insurance rules before derestriction, ECU work, exhaust changes or power kits.
4. Change one thing at a time and keep the original parts until the result is proven reliable.

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 Suzuki DR650 fuel pump connector power disappears with tank installed 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.
