Drop In Fuel Pump Module Connector Wiring Harness; For Use w/Fuel Module PN[12-952]; EFI Fuel System; Gasoline;
On many GM applications, the wiring harness that connects to the fuel module is generally not inspected when completing a repair of the fuel system. This harness is prone to failure and can lead to a misdiagnosis of a vehicle. Loose pins, cracks in the connector housing, and worn wire crimps can simulate symptoms that would be diagnosed as issue with the fuel pump. NOTE: please check Engine Code to correctly identify. ***When replacing the fuel pump harness connector be sure to remove as much of the old wiring as possible. For example, if the connector had a poor connection this would create a resistance problem resulting in heat. This excessive heat melts the wiring insulation allowing moisture to enter and corrode the wiring, resulting in future problems. ***
