Hello all! Thanks in advance for your input.
My 2007 Speedster 150 has only 51 hours on it. Runs like a top! Until last week. Suddenly threw a p0231 engine code...
P0231 Low Voltage Fuel Pump Secondary Circuit
Checked the pump and it works great with 12 volts. Checked the harness however and it's only supplying ~8 volts. Fuel pump fuse on ECM tests at ~12.5. Pins on harnesses and all wiring is spotless.
Can anyone point me to the next likely culprit?
