The engine will not start.

Found that an earth wire at the ECU pin C1-21 had failed inside the ECU. Bypassed that earth by putting that earth straight to a ground connection and the engine started. The ECU was sent away to be repaired. After installing the repaired ECU the engine ran for 10 seconds and stopped. Found the C1-21 earth had failed again. Installed and programmed a secondhand ECU.
