Before you replaced fuel pump, did you check proper voltage and ground at the pump? Did you use a gage and check fuel pressure, engine cranking.
With engine cranking, did you visually check for spark at the spark plugs and fuel injector pulse? If your missing all three, check for rpm signal.
Some fords have trouble with maf sensors. I'm not saying replace anything, you need to do some more testing.
Can you check for applicable trouble codes?
