You need to find out if it is fuel or spark related, spray some starting fluid in the intake while someone cranks it over, if it fires off and runs briefly then it is fuel, if not then it is spark. There may also be a stored code in the memory that might help you further along with diagnosis.

My 2002 Ford Mercury Mountaineer has gas in the oil it's getting gas but no fire what's wrong

Change the oil and filter before you do anything else, you don't want an engine explosion, then look at the fuel pressure regulator, see if it leaking fuel into the vacuum line, take the line off and just turn on the key and see if fuel sprays out, if it does repalce the regulator. If no fuel there then you may have stuck injectors, a pressure bleed down test will tell if that is happening. You should also remove the spark plugs and see if they are fuel soaked, if they are leave the plugs out and let the fuel evaporate for a few hours, you should repalce the plugs at this time too so you know you have a good set. Then check for spark at the coil towers, if no spark it could be the cam and or crank sensors, it may or may not have a code stored for those, a good scan tool is a requirement if you going to work on late model vehicles, one with live data and freeze frames capability. If you want more responses start a new post, this one is a year old and most likely not followed.
