My car has been sitting for a long time I put a new transmission in wiring harness ignition (immobilizer matched) ecu from a 2002 and it have no spark or gas fun part the key(immobilizer light) does not turn on. Crank no start I have swaped pin A13 to A16 becouse that's the only change I can see with the immobilizer system so ease any help is appreciated I need it I'm loosing my mind I also have 2 matched ecu and ignition to rule that out as a problem.

The ECU I purchased is key matched with new ignition it's comes as a set
