Fuel Pump Relay: Description and Operation
NOTE: The following information is intended to be used in conjunction with the electrical diagrams.
CIRCUIT OPERATION
Circuit A14 from the Power Distribution Center (PDC) supplies battery voltage to the contact side of the fuel pump relay. Circuit A21 from fuse
14 in the fuse block supplies battery voltage to the coil side of the Automatic Shut Down (ASD) relay. The Powertrain Control Module (PCM)
provides the ground path for the coil side of the relay on circuit K51. Circuit K51 connects to cavity 51 of the PCM connector.
When the PCM grounds the fuel pump relay, the contacts close, and connect circuits A14 and A141. A 30 amp fuse in cavity D of the PDC
protects the A14 and A141 circuits.
