So you have a dead ECU…..
Might start with checking the fuses that power the ECU.
From there you’ll need to check powers and ground at the ECU connector(s)
If that all checks out good you’ll need to test the 5V ref voltage output from the ECU and to all the sensors to see if the 5V ref is open,shorted or just not present.
