    No ECU light...

    If you plug in an ECU and no Spanner or ECU light shows up does it mean the ECU is knackared?

    Basically just fitted a 2nd hand ECU to replace the one that is faulty, the 2nd hand one doesn't bring on the ECU lights at all. With mine the car runs, just all readings are maxed out!

    not positive but i should imagine no ecu light is a good sign, does it briefly come on when you swith on the ignition and then go out? also is the car running??
