Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Fairly common issue with VZ.
The PCM (computer) is not enabling the start relay.
9 out 10, the PCM is the cause, and requires replacement, preferably by Holden.
Have done many on VZ.
Hope this helps.
Do you need any further help?
Does the immobilizer light turn off prior to trying to start?
I hope my advice has been of assistance to you.
Have you had any success with your problem?
