    I have a 2011 KW T800 Cummins ISX motor and have a starting issue that nobody seems to be able to correctly diagnose. It intermittently starts, sometimes drags, sometimes fires right up.

    New batteries (gel), 2nd new starter in a week, new battery shutoff switch and cables, cables all look good with no corrosion, alternator testing good.

    Anyone have any suggestions of where to start? I was told since it came from Ohio, check the de-population plug where the wires go through the floor under the cab?
