Town & Country SWB FWD V6-3.3L VIN G Flex Fuel (2000)
Fuel Pump Relay: Description and Operation
Fig. 1 Powertrain Control Module (PCM)
The fuel pump relay is located in the PDC (Fig. 1). A label affixed to the underside of the PDC cover identifies the relays and fuses in the PDC.
The fuel pump relay supplies battery voltage to the fuel pump. The fuse is located in the PDC. Refer to the Wiring Diagrams for circuit information.
The PCM controls the fuel pump relay by switching the ground path for the coil side of the relay ON and OFF. The PCM turns the ground path OFF
when the ignition switch is in the Off position. When the ignition switch is in the ON position, the PCM energizes the fuel pump. If the crankshaft
position sensor does not detect engine rotation, the PCM de-energizes the relay after approximately one second.
