Hey everyone I’ve come with some good news for once haha. So I’ve managed to diagnose this starting issue with the VX and I thought I’d just let everyone know incase something similar happens to them. Like I mentioned before I was getting an intermittent signal from the BCM/NSS at the start relay, so I knew that it had to be one or the other, I replaced my NSS (neutral safety switch) and it didn’t fix anything. So I did a bit of research on the BCM’s and the wiring with it and I managed to find out that the BCM provides an earth for the NSS meaning that it will stop the car from cranking over since the earth isn’t passing through to the NSS. So after testing for broken wires it turns out that the BCM is just a faulty unit. Now my issue is that I don’t know what bcm my car should have in it. It’s got power windows, central locking, ss spotlights, cruise control and ABS.
