I have a 2007 Holden Captiva 3.2 V6. It has a full service history and has had the timing chains done. I was driving home and the engine turned off. Luckily, I was only going 40 km/h, but there was no warning at all and now the engine won't restart. Has anyone else had this problem?
Does it crank over when you turn the key? If it doesn't I would suspect a problem with the cam timing chains that has caused serious internal damage. If it cranks over, but doesn't fire I would be looking at an engine sensor that has failed. Take it to a dealer and have them check it on their diagnostic gear.
