When I’m reverse and under power like if backing up a steep hill, it hesitates like fuel is intermittently spitting gas, goes in and out and has no power. It must be a fuel problem?  What would cause it to pulse fuel in reverse only ?

I believe that is actually a  Hisun HS700UTV Crew (same as the Coleman UT700). They have a 10 MPH limiter for reverse gear--If the vehicle (or its rear wheels) are going over 10 MPH it will cut fuel and sputter. The same black box is used for the seat belt "safety" feature...

      I have a Joyner Trooper 1100 4 place that has been sitting for a number of years. I have everything taken care of but i can't get the fuel through the injectors. Fuel pump puts full pressure on them but they don't turn on or spray fuel. Any ideas?

      Hi
      I have a 2022 hisun sector eps 550. 30amp fuse is blown for eps. Checked the motor and it’s fine. Opened up the controller and found a bad diode. Dealer wanted 500$ for the controller. Just posting this in case it helps someone. I couldn’t read numbers from the old one so just took a guess and replaced it with a 100v 3amp diode.

      2002 ranger 500 4x4 stopped running and wouldn't restart. Service manual wiring diagram helped identify the hub safety switch as the culprit. Using jumper wires to bypass  switch allowed the engine to start and run normally. Inspection of switch showed melted epoxy and a strong smell of burnt electrical. Unable to find replacement part either used or new. Is there a work around other than jumper wiring?

      the regen braking on my e1 has stopped working unless (for eg) I am going down a hill in low and it's slowing things down to stick to the 10kph limit. when I drive and take my foot off the accelerator it's not initiating the regen to slow things down and instead just coasts at whatever speed it is at, or speeds up as the regen is not limiting it. the brake lights work, so it's probably not a fault with the sensor on the brake pedal
       
      hoping someone else might be able to provide some suggestions on things to check, as the mob that I bought it off seem to have gone silent on me
