Fuel Delivery Module Before replacing the fuel module for DTCs P0461 and P062A and other not start, long crank, fuel gauge accuracy and drivability issues, the technician should disconnect the electrical connector at the pump and perform a visual inspection of the connector for and bent, spread, or pushed out terminals. Repair any issues found. Reconnect the plug and perform a push pull push to ensure the connector is fully installed. Then perform 3 keys cycles and listen to hear if the fuel pump is operational.

FUEL PUMP/LEVEL UNIT MODULE For vehicles with Saddle Fuel Tanks, need to determine if there are any DTCs in wiTECH. Follow Service Diagnostics published prior to making any changes. Review any existing SOL or TSBs published for customer complaint issue. Only the Fuel Pump Module should be replaced if there are DTCs associated with the Fuel Level Sensor number 1. Only the Auxiliary Level Sender should be replaced if there are DTCs associated with the Fuel Level Sensor number 2. If there is a mixture of DTCs between the Fuel Pump Module and the Auxiliary Level Sensor, then investigate if there is a Jumper Harness or circuit issue between the Level Sender and the PCM. Verify fuel transfer between auxiliary tank and the primary tank by monitoring the auxiliary level sensor to verify it drops after driving.
