tried cleaning map sensor but still cutting out.

My Defender is is cutting out and running rich. You can smell raw fuel when idling. Check engine light is on but I am not seeing any codes unless I just don't know how to get the codes. I replaced the fuel screen on pump. It wasn't that dirty. Any idea where MAP sensor is? Might add sparks plugs are damp. Thought I would try to check that before going to Fuel Pump. How to you clear check engine light anyways once I fix the problem?
