My car has been through a variety of checks on this.
I thought it was an immobiliser issue on the Sigma alarm for a while but as it turns out, I don’t think the Sigma S32 immobiliser is connected!
I now think it maybe that the key is no longer coded to the car after the car was left stood for 6 weeks and the battery went entirely flat. The reason I think this is because the ignition is being cut after just 2-3 turns of the engine but the fuel is also being cut. I took the supply line off the fuel rail and no fuel at all was coming through. I can hear the fuel pump relay clicking when the ignition is switched on but I can’t hear the fuel pump prime…
My next thought; Has the car lost it’s coding to the key chip? I have two keys for it, neither of which start the car. The fact that both ignition and fuel are being cut suggests it could be the car’s immobilisation system. The Sigma S32 is only single point immobilisation so would only cut on one or the other.
If this is the case, is there a way I can go about re-coding the keys to the car?
Thanks
