Blown Something When Wiring Up Head Unit - Now No Start!

[Crowy82]

Hi All,

I was installing a new head unit and something has blown whilst i was doing so. I didn’t have the Battery disconnected when installing the unit (I'm an idoit!!!) and some of the bar wires crossed paths. The dome light went and the car won’t start now – the keyless remote also wont work. All fuses are OK and all other electrical items are operational. I’m thinking that the immobiliser has something to do with it but I have no idea how it is controlled or where is it placed – I imagine that its quite hard to get too as to remain tamper proof.

Has anyone else experience simular problems and can it be repaired by a novice?

Also worth noting that Ive checked the fuses under the hood. There are 3 fuses in a row: Dome | ECU | Radio - all three fuses are Ok. I was thinking that these three components are wired together and something has blown causing failure in all three. I know the Dome and Radio arent working and the ingnition is turning over so maybe it is the ECU!! Would this also explain why my keyless entre isn't working??

So could it be the ECU or the immobiliser??

Cheers,

Crowy
