Was the new ignition switch definitely a goodun? My VR6 would not crank over when you turnt the key to start, however, when you turn the key just to on all the ignition lights would turn on, pointing to a fault with the ignition switch. To over come this I unplugged the plug that goes straight into the back of the ignition switch, stripped a small part of the thick red wire and also the thinner red wire with a black line on it, attached two wires so that they are accessible, put the plug back into the ignition switch, turn the key to on, touch the two wires together and it started first time.
