Fuel Pump Relay: Description and Operation
CIRCUIT OPERATION
Circuit A14 from the Power Distribution Center (PDC) supplies battery voltage to the contact side of the fuel pump relay.
In the START or RUN position, the ignition switch connects circuit F18 from the 10 amp fuse in the junction block to the coil side of the fuel
pump relay. The Powertrain Control Module (PCM) provides the ground path for the coil side of the relay on circuit K151. Circuit K151 connects
to cavity C19 of the PCM.
When the fuel pump relay energizes, it connects circuit A14 and circuit A61. Circuit A61 supplies voltage to the fuel pump module.
