How does the ECU work on a King Quad?
ECU works in friend’s quad. Changed temperature sensor, rectifier, ignition coil, air pressure sensor, fuel pump, fuel pump relay, added chassis ground. I know I have fuel to injector but none through throttle body.
Why is the fi light flashing on my King Quad?
Changed all that out and now the FI light flashes once every second. Put quad in dealer mode and get -C00 code and FI light stops flashing. Back to user mode and the FI light starts flashing again.

What kind of injector does a King Quad use?
Injector works in a bench test with 12v and 30 psi air. I’ve pinned out all sensor connections through ECU plug and all are good and sensors check out within specs based on service manual info. The quad just cranks over with out a hint of trying to start. Tried dumping fuel directly into throttle body and nothing.
Why does my King quad engine not start?
In that chart it should show the values on your pickup off your stator. If it is flat lined when you crank the engine it could be defective or wire is pinched and grounding to frame. As well what that connects to it will send a signal to the ECU and that might have a melted wire or damaged .
