Trooper LS 2WD V6-3.5L (2001)
Fuel Pump Relay: Description and Operation
In order to control the FP operation, the FP relay is provided. When the starter switch is turned to "ON" position, the FP relay operates the FP for 2
seconds.
When it is turned to "START" position, the Power Train Control Module (PCM) receives the reference pulse from the Ignition Control Module and it
operates the relay, again causing the FP to feed fuel.
