NOTE: Most vehicles are equipped with a knee bolster to prevent knee injury in the event of an accident. The knee bolster runs along the entire length
of the lower dash. To properly access the fuse/relay panel for servicing, the knee bolster must be removed from in front of the fuse/relay panel.
OPERATION
The Fuel Pump relay receives battery power to energize from the ignition switch and is grounded by the Motronic Control Module. The switched
battery power that flows through the relay comes from the battery source terminal of the fuse box. The switched battery power flows through the
relay to the transfer and main fuel pumps as well as the oxygen sensor heating element.
When the ignition is turned ON the Fuel Pump Relay is energized for only 1 or 2 seconds then the Motronic Control Module shuts off the relay by
removing the ground and de-energizing the relay.
When the ignition switch is turned to the START position the Fuel Pump Relay again comes on for 1 or 2 seconds only. The Fuel Pump Relay is
kept energized after the Motronic Control Module receives an rpm signal from the ignition system, this rpm signal confirms that the engine is
running above 225 rpm. The purpose of this feature is to prevent flooding while starting, and to stop the fuel pumps in the event of an accident and
fire.
