Fuel Pump Relay
The Powertrain Control Module (PCM) controls fuel pump relay operation by controlling fuel pump relay ground circuit. PCM opens ground circuit when ignition is off, and completes ground circuit when ignition is on, to provide fuel pump operation. When ignition is first turned on, if engine rotation is not detected, PCM de-energizes fuel pump relay after approximately one second.
Fuel pump relay receives battery voltage from ignition switch and fuse or fusible link depending on application. Fuel pump relay is located in various locations depending on model application. See FUEL PUMP RELAY LOCATIONS table.
| Application | Location |
|---|---|
| All Models | In Power Distribution Center At Driver's Side Front Corner Of Engine Compartment |
If fuel pump relay or control circuit becomes defective, a Diagnostic Trouble Code (DTC) may be stored in PCM. See TESTS W/CODES - 2.5L article for diagnosis of DTC for fuel pump relay. For additional information on diagnosis for fuel pump with fuel pump relay and control circuit, see NO START (NS-2A) TEST in TESTS W/CODES - 2.5L article.
