Car is a non starter. On initial key on there is no fuel pump buzz and on cranking there is no spark,injector duration or fuel pump running. The immobilizer shows its correct sequence when arming and disarming.modis shows no communication.ecu has the correct lives and earths according to autodata. Isuspect the immobilizer is not making the ecu come alive but am unsure how it works or where the immobilizer is in the car.on one wiring diagram it shows an input from a "key transponder"on to term b12 of the ecu but that is the only reference to an immobilizer i have found.anyone know of a way to input a signal on to b12 to fool the ecu if so what kind of signal.

Any help gratefully recieved
