Intercooler pump will not turn on. Applying 12 volts to the yellow lead by relay turns pump on. Put a new relay in but still doesn't turn on. Where should I look next? I'm using $59 and temp is set at 19d celcius for turn on.
The yellow wire is the power wire to the pump and the pump works when 12v is applied. I think there is a flag in code 59 I can't find to turn it on or the ecm isn't sending the on command to the pump.
