help needed VZ V8 one tonner issues

[Souljah]

car seems normal to drive just no fuel , temp gauge (engineering mode says temp is -40? and all the zeros in faults but for the 17th one which holden states is not used and not even picked up with Tech2) no air con, shift mode or gear indicator (auto).

Sounds like similar symptoms that happen when i'm doing a data log on our VY Super 6. Car drives fine but the dash and climate do funky things as the data cable is interrupting the chatter from the cars modules to the dash.

Had the car to an auto elect. today and he has had the similar faults with a crewman and he said it was the PIM. So went to Holden and there are none listed in Aus. or any PCMs. They have placed one on back order for me but could take weeks to just get availability. I then tried bursons but they need the old pim, pcm and bcm plus the keys to be sent to Melbourne to be all linked at a cost of $635. the Holden PIM is $105, I don't like the idea of pulling the car apart and send them off in the post, but I might have to and still no guarantee that this will fix my problem.

Bring us up to speed here is the PIM used on both Autos & manuals? Couldn't you buy a s/h pim & have a switched on auto/elec/mechanic relink the pcm & bcm at the same time?

I looked into a s/h pim but they tell me they have to be unlinked from the donor car before removal if not there unusable or programmable. They also need to be from the same vehicle or matching part numbers being a one tonner its going to hard to find one.

Ok, Try these guys in Sydney:
Commwreck Auto Dismantlers
Address: 23 Ilma St, Condell Park NSW 2200
Phone: 02 9792 7511

Bought my spare ECM from them from an exact Crewman eg same part no: at the time took it to Sonny & he sorted no problems.

Thanks Mick I will give them a call in the morning. The problem here in the country is the lack of good tuners, I have to travel to Brisbane as its closer for any tuning.

Wow, what an annoying problem!

It's issues like yours that cause most people to just give up and sell their cars.

Don't do that.... you'll eventually find the cause and once it's sorted out you'll be happy and everyone reading this will benefit.

wow, what problem ........... is trading it out of the question?

Had the car to another mechanic today and they thought it was the key reader and then the instrument cluster and then wrong starter motor because of the noise it was making when cranking. So bit the bullet and removed the PIM, BCM ECU and the 2 keys all boxed up to be sent to injectronics in Melbourne tomorrow. I really hope this fixes the problem as I'm not 100% sure ( or any auto elect or mechanic) what the exact cause is. I will report back when they return and installed.

Problem fixed, I received my computers back today and installed them and all fixed the people at Injectronics tested my PIM and it was faulty, they didn't have a reco one and repaired mine.
The cost was $635.
Thanks for the replies for help and keep this in mind if your or someone else's car is doing this type of thing as the guy at Injectronics (Ken I think) said its a common problem with the VY VZ V8s and strangely they virtually never get the PIM faults in the V6s ( must be a different band/computer).
Thanks Allan
