Just in case anyone runs into this situation with a Kingtech which Inhave read about happening to a few people online...about 2 months ago I had a flameout and pump wouldn’t pump after that. Kingtech told
me to run the pump backwards by hooking up a small battery reverse polarity. I finally got around to doing it and then ran it normally and the fuel pump worked again and engine started. Either something was clogging the pump or the pump was stuck. Like I said, I am not the first person this has happened to and I saw they recommended running backwards to “exercise” it.
