Ok, its not my immobiliser, the auto elec totally disconnected it... And gave some credit to John for his bypassing (job offer still stands lol)
There is a huge short coming from one of a few wires leading from the boot to the front... We tested it a good dozen times, starting the car, then letting it die... first 3 times it lasted same as last night 40secs or so... THe rest its just shorting straight away, which is good because a constant short is easy to find...
So getting it towed to the auto elec's workshop on monday and should be ready monday afternoon...
I am now going to open a new bank account with SKYLINE OWNERS BANKING just to make it easier when spending money to keep my peice of shit japanese car on the road
