Fuel System Overview
The engine control module (ECM) enables the fuel pump relay when the ignition
switch is turned ON. The
ECM will disable the fuel pump relay within 2 seconds unless the control module
detects ignition reference
pulses. The ECM continues to enable the fuel pump relay as long as
The vehicle may have a compass
display in the Driver Information
Center (DIC).
Setting the Compass Zone
Under certain circumstances, such
as during a long trip or moving to a
new area, the compass zone will
need to be reset. If the compass is
not set to the correct zone, it may
give false readings.
