    Okay as some people on here would know my old boy has been having some problems with his VT.

    Many workshops have said that its the computer so we baught another to see if that was the problem.

    Everything on the car (which the computer came from) is the same as Dad's but with the new computer in the car it won't start.

    Any Idea's?

    did you get the new BCM (computer) programmed by Holden (only one's that can do it). The BCM needs to be programmed, new key remotes will need to be programmed and BCM to PCM link needs to be done before it will start.

    If I understand correctly, you have only changed the computer. If that is the case then you need to get the BCM linked to the computer. You need to get Holden to do that.

    you just need to get the BCM & PCM linked so the security system will work, no need to replace it
    can only be done with the correct diagnostic tool.

    Okay cool. We are gunna try something completely different to what the workshops have suggested in the morning (Leads, Plugs, Fuel Filters (I think theres 2), Drop Old Fuel and run a new batch of Premium) and see if that has any effect.

    If it doesn't it will be going straight to the Auto-Electrician on Monday morning to have this BCM & PCM unit linked as suggested above.

    A lot of auto electricians wouldn't have the correct machine for the job, you may have to go to Holden. It won't hurt to do the other things you mentioned but it still won't start without getting the PCM and BCM linked. I know this from when I had to get a new BCM.

    Yeah we did the other things and with the original computer in the car it still feels like its hitting a great big wall in 1st and won't kickdown when you boot it. Kickdown sensor has been replaced also.

    If this BCM PCM Linking has no effect he is looking at selling it and buying a VZ.

    BCM & PCM, its all jap to me, I have trouble with my vt, it runs like a slug, the engine warning light and oil pressure stays on, with the transmission hesitant. Thinking the car was about to die, I was told the computer needs replacing. Then only to find out, the current 1 might only need relearning, via what i have been told is a tech2. Luckily enough my bro works for nissan and says they should have 1, Here's hoping:)

    nissan wont have a Tech 2 theres no nossan applications that use it.
    sounds like you need to take the car to someone who knows what they are doing.
    i would guess your ABS module has failed.

    Didn't have to... Dad decided to bite the bullet and take it to Holden... They ran thier Scan Tool and in about 3 minutes flat they knew what it was...

    The AFM was rooted... Seems they have a billion little wires in them that sense how much air is flowing through it and somewere along the lines a piece of grass got through the POD and smashed these little wires. This was causing the Computer to get a false reading of Airflow, Hence when you boot it there was fuel not being burnt due to not enough air and this was pushing it into Safe Mode.

    I did an engine management course a few years back and most of the techs were making a living refitting original air filters and MAF sensors. especially when people fitted the oiled type air filters
