WM Statesman, petrol only V6?
No codes, I would say a fuel pump is a possibility.
When this happens, is it a dead cut, like turning the key off, or like running out of petrol?
That is unusual for VE, WM.
And no codes.
Can we continue tomorrow please?
I'll be here in the morning.
I'm in QLD.
Are you checking all modules for codes, or just the PCM?
The stalling happens only at idle?
Could be one of a few things, but very rare for VE.
It could be an immobiliser issue, the BCM, an ignition switch dropping out, or even the key.
If you haven't already done, the whole vehicle needs to be scanned for codes.
I have yet to have a VE onwards not log a code for this style of condition.
I would say normally they don't start up straight away.
Do you have another key?
Is repeatable often?
Sounds like a power supply or ground (poor connection, loose terminal etc)to one module PCM, BCM etc, that gets warm/hot after some driving.
It then becomes a voltage drop, the module concerned does not get what it should, and the drop occurs.
At 250km from a Holden dealer, it may be difficult for you to fix this.
I hope you have a local mechanic with some late GM experience.
Can you try the other key to eliminate it as a cause?
I would consider that to be normal.
If you keyed off for about 15 seconds, the pump would run again for a few seconds.
How loud is the pump when you hear it prime?
When it does stall out, do all the warning lights come on the instrument cluster?
Usually is the case for VE.
The pump can give early signs of failure, generally starts as low power, although can get sluggish from running for long periods.
If you haven't had a pump replaced as yet, then this maybe the cause.
This problem won't be a fuel filter.
The fuel tank needs to come out to replace the pump assembly.
The rear suspension member needs to be lowered at the front to get the tank out.
I've done many, but would not want to do one at home without a hoist.
Hope this helps you.
How did you go with your problem?
I hope my advice has been of assistance to you.
That's great news.
They do seem to do everything better with a new pump.
Hope all goes well now.
