Customer Question

Hi Jeff, I have a 2006 Mercury Optimax with a constant beep/ alarm. I have tried to start it with the kill switch off and the mechanic has told me that this has burned the PCM/ECU. Is this a known problem and is there a service bulletin from Mercury om this?

Trying to start with the kill switch off can't burn up the ECU. Get me the serial number of the engine.
