    Hello all. I have a problem getting my ECU to display anything. I tried to get the unit to start the sequence of lights, according to the manual, but no lights show up on the console.
    Ive never had this happen before. Always could read the display from the ECU.

    Both sides? What made you want to check the ECUs?

    It's the 5-8 side ECU. Haven't checked the 1-4 side yet because it is in my garage with little room to open the passenger door. I'm going to roll it out tomorrow and check it.

    I was checking it because when I go to start it, it sounds like it's missing on one complete bank of cylinders.
    Don't know what caused it because the last time I drove it 2 weeks ago, it ran perfect.

    Welcome to Ferrari ownership :p

    Assuming no power is getting to the ECU, check fuse 14 in the footwell. This provides battery power to the LH ECU. Ignition power also goes the ECU, but there are no associated fuses to check.

    By the way, does the CEL light up normally during start? Is the bulb ok?

    Ah.. ok.

    The ECU controls power going to the CEL lamp (by providing an earth to a power relay) and also provides an earth for the lamp. It seems unlikely that the CEL would illuminate if the ECU was not getting power. That fuse may be ok.
