Immobiliser problems.

[Dualist]

Hi guys,

I hope you some here can help as this problem is starting to drive me insane.
I had the little swimming pool under the passenger seat that fried my immobiliser, I dried it out and the car still starts but doors don't lock and the windows don't work now.
So I brought a secondhand tested immobiliser, ecu, fob with pill and transducer, disconnected the battery, installed the gear and everything worked as it should but for some reason the car won't start. Swapped my transducer and pill and still the same issue, won't start. I spoke to the seller who is a porsche garage and gone through what I did and still engine won't start. They very kindly send out another set for me to try, I fitted this this afternoon and still the same problem, all the electrics work but just won't start.
To see if I'm not going totally mad I changed over to my ecu and immobiliser and car starts no problem but windows and locks still don't work.

Any of you guys know what I'm doing wrong or what else I should be doing when I do a swap over like this.?

Any help is greatly appreciated.
