FUEL PUMP OPERATION OVERVIEW
When the key switch is turned to "ON", the ECU
activates the fuel pump, which pressurizes the system for
start-up.
The ECU switches off the pump preventing the continued
delivery of fuel in these instances:
• If the key switch is not promptly turned to the "start"
position.
• If the engine fails to start.
• If the engine is stopped with the key switch "on" (as in
the case of an accident).
In these situations, the "check engine" light will go on, but
will turn off after 4 cranking revolutions if system function
is OK. Once the engine is running, the fuel pump remains
on.
As boost pressure increases, fuel pressure increases
due to the manifold pressure controlled fuel regulator. It
is NORMAL to see fuel pressure fluctuations as the
throttle varies.
