- 2007 VE SV6
A few peeps on the boards have mentioned problems with the VE engine becoming flooded.
Thought this might be useful....There's a feature called 'Clear Flood Mode'
This is for VE Commodore 2007 - 2009: BERLINA/CALAIS/OMEGA/SV6/SS/SSV/LUMINA/SPORTWAGON
STARTING MODE
With the ignition ON, before engaging the starter, the engine control module (ECM) energizes the
fuel pump relay for two seconds allowing the fuel pump to build up pressure. The ECM first checks
speed density, then switches to the mass air flow (MAF) sensor. The ECM also uses the engine
coolant temperature (ECT), throttle position (TP), and manifold absolute pressure (MAP) sensors to
determine the proper air/fuel ratio for starting. The ECM controls the amount of fuel delivered in
the starting mode by changing the pulse width of the injectors. This is done by pulsing the injectors
for very short times.
CLEAR FLOOD MODE
If the engine is flooded with fuel during starting and will not start, the Clear Flood Mode can be
manually selected. To select Clear Flood Mode, push the accelerator to wide open throttle (WOT).
With this signal, the ECM will completely turn OFF the injectors and will maintain this stage as long
as the ECM indicates a WOT condition with engine speed below 1,000 RPM.
