Got a 03 XZ6R that’s not starting. Get no prime from the fuel pump when key on. Checked connection at fuel pump, found no power. Traced to relay. Swapped relay and still no prime. Jumped relay and pump comes on. Have good power at control side of relay. Ground side of relay looms to being going to ECU. I have to check wiring from relay to ecu. If this is good, will I need an ECU or is there something else that I’m missing?
