Right in your first post you said all the 5V outputs are missing, have you checked why? I wonder if one of the sensor supply lines is shorted to earth, no 5V, no anything. I have never found out if the sensor 5V is the same 5V as powers the processor etc. but these manufacturers are nothing if not cheapskates so it probably is. It might be worth unplugging the ECU and then checking each 5V signal line for resistance to earth. Shaun.
