Remove battery pack from the drill and identify polarity on its connections (using cheap analog voltmeter) 2.
Potentialcauses of a P0231 code include: Bad FP (fuel pump) relay. Harness chafing causing open in fuel pump supply circuit. Loose/damaged connectors. Open in feedback circuit. Fuel pump fuse blown due to short to ground. NOTE: If no drivability complaints are present and P0231 code is stored, suspect open in feedback circuit between splice
