Sorry I ask my questions in the reply. Three more questions, and I will leave you alone. If the ecu is bad, is it possible to get the vehicle started before replacing it? Do you think replacing the ecu is very difficult?

Replacing the ECU is easy. Disconnect the battery, unplug the wiring harness to the ecu, unbolt it and reverse the procedure. If the ecu is the cause of the engine not starting, it is an internal non serviceable issue that has no temporary fix.
