Just wanted to give update . It was the ecm. Put new one on and got spark immediately to front cylinder. Ran but smoking and no power. I checked back cylinder and no fire. Pulled coil to check with meter and found wire was not getting good connection where it plugs into coil. All good now . She will scream !!!. Next is to figure out why 4x4 switch wont turn. Thanks for all the imput....
It does, I switched them around but didn't make a difference. I'm looking at new ecm fron $80 - $150. Alot of them say for hisun 800 but have different numbers.
I checked wires going to coil, I get 12 volts on one of the wires when I turn the ignition on . Checked all fuses, dont know if there is anyway to check all the relays. I'm ordering new cpu today.
Any luck on this ?? I have the exact issues. No wire to oil sensor and same white plug. Cant get spark . New crank sensor . About to order new ecm ?????
