Hi. got one of these on my car. its a thatcham cat 1 with immobiliser.

Based upon the Ai606

come to start up and i have no spark and the feul pump isn't coming on.
(cant hear the usual buzz)
All earths are ok. all fuel pump relays are good.

Spoken to a couple of people and they think it could be the immobiliser.

Is this a possibility? The car opens fine and cranks over ok just no spark and cant hear the fuel pump no more

Any help would be apreciated.

Thanks
