Check the spark plugs on those cylinders after cranking, are they dry, are they wet? If they are dry, I'd have to check injector pulse. Did you use a spark tester on those spark plugs, you can open the gap on the tester, to see if spark will jump the gap, if not, it is a weak spark. You may need to check cylinder compression?
