Hello 1st thing to check is if the fuses for the ECU are intact and there should be a relay in the underbonnet fusebox too if the fuses are intact then check if that the relay is 'clicking / switching ' when the key is switched to ignition if thats OK then check the small earth wires that run out of the engine bay wiring loom and terminate onto the engine with small ring terminals, as these are the specific ECU earth connections
