Could be flooding if pressing the accelerator fires it.

You say it is weal cranking over?
I would check the battery first, followed by a fuel system pressure test to check for leaky injectors or a leaking fuel pressure reg.

If it's cranking OK then the battery should not be the problem. Most likely the engine is flooded as VR38 suggests. The Holden VS Service CD says the following:

Clear Flood Mode
If the engine floods, it can be started by pushing the accelerator pedal down all the way to the floor while cranking the engine. The ECM/PCM then pulses the injectors with only a four millisecond pulse width, which should "clear" a flooded engine. The ECM/PCM holds this pulse width as long as the throttle position sensor input indicates the throttle is nearly wide open, and RPM is below 400.
If the throttle is held wide-open while attempting to make a normal start with a non-flooded engine, the engine may not start. A 4 millisecond pulse width may not be enough fuel to start a non-flooded engine, especially if it is cold.
