Hi there,

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?

Gary

Customer: replied 2 months ago.
Dead cut,although no lights come on
Customer: replied 2 months ago.
V6 petrol only
Expert:  Gary replied 2 months ago.

That is unusual for VE, WM.

And no codes.

Can we continue tomorrow please?

I'll be here in the morning.

Are you in west au?
Expert:  Gary replied 2 months ago.

Good morning,

I'm in QLD.

Are you checking all modules for codes, or just the PCM?

The stalling happens only at idle?

Gary

Customer: replied 2 months ago.
Hi Gary,l am on a farm and don't have a dealer within 250 km,engine dies when driving, put into n,do as described earlier without stopping the vehicle then continue driving,no modules have been checked.

Hi Peter,

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?

After vehicle sitting o/night it will be ok for say half an hour,then stalling regularity appears to become closer,when returning home on Sunday when issue first began, after two hours driving it was stalling every two minutes.I have another key
Expert:  Gary replied 2 months ago.

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?

Gary

Customer: replied 2 months ago.
After stalling, when ignition is turned on I can hear the fuel pump pressuring,initially twice, then third time no fuel pump noise,so I assumed it was fully primed, is this correct?
Expert:  Gary replied 2 months ago.

Hi Peter,

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?

Gary

Customer: replied 2 months ago.
Not overly loud,about to take for a run to test other key
Expert:  Gary replied 2 months ago.

Ok Peter.

When it does stall out, do all the warning lights come on the instrument cluster?

Gary

Customer: replied 2 months ago.
No not until key has been turned off and on,have tried other key,no change.
Thinking must be fuel pump\filter
Expert:  Gary replied 2 months ago.

Hi Peter,

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.

Hello Peter,

That's great news.

They do seem to do everything better with a new pump.

Hope all goes well now.

Kind regards
