2013 Hisun 700 not making power

Have you checked the digital clock on the dash for codes?

A lot of the models made in the last decade or so, blink the clock, and you count the blinks, to get the code. Others will display a digital number, that represents a code on the clock instead.

I haven't seen any blinking, no. I'll double check though.

Sometimes it's displayed as a number on the clock. It might not blink, but just display the number. I don't know how many sensors there are on yours. But with what's going on with yours, there should certainly be a code. Have you looked at switching the upstream, and downstream exhaust sensors?

^^^this^^^ The codes display just like the clock display, but the colon (":") is dimmed out--they are easy to miss except that they do not change each minute--The EPS  (Engine Protection System) warning light should be on if any error codes have been logged.

I haven't seen mention of the oxygen sensor (in the exhaust pipe)  in this discussion.  A dead or dying O₂ sensor will  generate a low, or no,  output voltage; this makes the ECU think the engine is running lean, it compensates by adding fuel, I.e. making the AFR rich. This can happen without triggering an error code.

For more (than you probably want to know) about O₂ sensors--including how to test them with a multi-meter and a propane torch--click here.

Well there were no flashing lights on the dash. We think we resolved it though, we replaced the injector and it's running much better. Maybe something got stuck in there? Hopefully it stops burning through plugs now. It still has it's hiccups like wants to stall if sitting idling sometimes and hot, and i stomped the throttle once when colder and it had a good bog. Definitely doesn't run like new.

If you find out the problem please share.  Mine is do the same thing. I have replaced all the electrical components and still doing the same thing. The only thing that I have not replaced yet is the wiring harness. My 02 sensor is also shooting sparks out when starting.

Changing the injector seemed to have fixed it. We ended up selling it this spring.
