Scanned for fault codes?

Removed imob??

Well I only finished it this evening so haven't scanned yet I will have to get some body to do it tomorrow, I thought the imobiliser would have been ok as I used all the new things from the same car. The only thing is that when I press the buttons on the new key nothing happens?

If it was immobiliser related surely it wouldnt start atall!?
Fuel
air
Spark
?

[Toby]

I think if the clocks are unplugged that makes them need deciding again??

Double check everything

Earth ok?

Not always, they tend to start then cut out straight away.

I have fuel coming through and spark as I sed it starts then cuts out after about 3 seconds and I can hear one of the relays clicking, just the let u know I have a 1999 car and the engine is a agu from a 2000.

Earth is good.

It seems weird to me I mean how could a key work on one car then move the ecu clocks ignition barrel to a diffrent car then it won't work? Surley all this problem with it starting then cutting out 3 seconds later and the fact the key is not working it must be an imobiliser fault? I had a problem with a few of the electrical conections expesially the 3 that are underneath the scuttle pannel on the drivers side 1 of them was differnt it had 3 wires on the 1.6 and 4 wires on the 1.8t so I chopped the 1.8t block off and connected the 1.6 block to it. Anybody come across this before if so what did they do? Any help appreciated.
