You need a scantool - (usually holden) that can access the BCM to read any logged error codes stored in the module.According to a workshop manual the high series BCM(berlina,calais,statesman),(Im not sure about the low series), can be reset by removing the fuel pump fuse which is under the bonnet in the fuse box for 1 second .It also says that the BCM will click when the fuse is re installed and the interior light will come on and the red security light will start flashing.These things confirm it was successfully reset.

Can you hear the fuel pump prime and then stop when the ignition key is turned from off to the on position?Has the sparkplug leads got spark,a strong blue/white spark,not a weak yellow/red spark?Check them all one at a time,use an old sparkplug with a wide gap to test the leads.Check these things and get back to us here and let us know how it went.Cheers.
