Fuel Pump Motor Helpful Information

Circuit F18 originates in the fuse block where it connects to a bus bar fed by circuit A21. In the START and RUN positions, the ignition switch connects circuit A1 from the Power Distribution Center (PDC) to circuit A21. A 30 amp maxi fuse in the PDC protects circuits A1 and A21.

Circuit F18 splices to feed the ABS control module, EGR solenoid, Torque Convertor Clutch (TCC) solenoid, and the EVAP/Purge solenoid.

Circuit F18 also connects to a bus bar in the PDC. The bus bar supplies voltage to the coil side of radiator fan relay and A/C clutch relay, as well as to the fuel pump relay.
