Have you tried turning it off and on again.
The engine computer on a 98 Holden Vectra is reset by disconnecting the battery for 30 seconds. This allows the computer to power cycle much like a home PC.
If its vectra b to reset ECU you have to turn key so all display leds light up then off and do it 8 times if i remember rightly, this resets ECU to factory settings.
