Hi, you should replace it cause it happens to all. I have a VN Persuit and I have to do all the things. But I think the VN is a good car and you should do it up.

I have had a 1989 VN Calais for three months now, the best car I have owned. Yet, for some reason, when I have only a quarter of a tank left, when I put my foot down, it coughs and splutters. Sometimes, even dies. Is this the fuel pump?

Hi, I have owned a 1989 VN Commodore for over a year now and have had to change the fuel pump twice. It was recently changed by a mechanic, but I only had it home for four days and I have yet another problem, it now won't start and I am thinking that it could be the fuel filter, any suggestions would be great thanks.

It should be on top of the fuel tank. You need to bring down the tank to reach to the fuel pump.

Hey guys I have an 89 VN Commodore Executive. My car has had its fuel filter replaced, and when I try to kick it over it does the starting bit, but it just actually won't start, it just kicks over and doesn't ever start? I thought it could be fuel lines? Any ideas? Need help ASAP. Cheers.

It could be the spark plugs. Replace them and gap them properly, and check the battery as well and the leads.

I have a VP Calais had for a year. The odometer is at 120k~. I have done a bit of work on it.
Here are some troubleshooting ideas if your car will not start, but cranks over. First turn the key to on so the dash light comes up e.g. engine light. Then go to the back of the car and listen for the fuel pump; it sounds like an electric motor at high rpm. If not, check the fuses. All good, then replace if you don’t hear the pump. If you do, then 90% of your fuel system is good.
The next thing would be your crank angle sensor; it lets the computer know where the pistons are, so it know when to fire the spark. It is located behind the HB. Coil packs do stuff up, but they don’t just stop and kill the engine in one hit, normally I might add.

I have a Berlina Commodore and you need to put on an external high pressure pump. This is a second pump combined with the internal fuel pump. The internal fuel pump is over worked with raw fuel that has not been put through a filter, as it picks up fuel, then goes through a fuel filter, then to the motor. Because the fuel is filtered after it is pumped, the dirt that goes through the pump wears out the inside of the pump, causing it to not work properly or even fail.
Also if there is only an internal fuel pump, it is overworked. So you need an internal and a external pump to take the load off the internal pump.

Hey, I've got a 1989 Holden Calais. Just trying to replace a thermostat. Having a bit of trouble. Any tips would be muchly appreciated.

To remove the thermostat from the rear of the motor on VN metal, sometimes the upper housing becomes glued to the motor - use Inox and spray around the stuck housing to assist in levering it up - do it several times during the day. Make up a metal collar to fit around housing, and weld this onto a piece of 3/4 water pipe. Put around the housing and use the water pipe section to rock until movement is felt, and then pull up and the housing will come off. Tried other methods, but this was the best idea I could come up with. You may have to leave Inox on longer to penetrate around the bottom of the housing, as some thermostats have been in the car since year dot.
