CHECK ENGINE LIGHT (MIL)

1998 Ford Windstar

Electrical problem
1998 Ford Windstar 6 cyl Two Wheel Drive Automatic 167000 miles

My 98 Windstar failed the emissions test recently because the MIL light is not functioning. It does not turn on when the ignition key is turned (engine not running) or at any other time for that matter. I checked with my OBD II scanner for any fault codes but there are none and everything seems to be working fine, so the MIL should not be lit when the engine is running. I have checked the bulb and swapped it for a working one, but still nothing. I will check for continuity to the ECM, but cannot think what else it could be apart from the ECM itself. Any ideas?
