The ATV starts up and idles fine for as long as you’d like it to. If you very carefully and quickly feather the throttle ever so slightly you can build RPM up around 13-1400. But if you try to easy the throttle in it will shut off. Pulled the plugs out and unplugged the fuel pump and cranked the engine both plugs have good spark but when you press the throttle in neither plug will spark. I’ve tried two different TPS sensors and made sure voltage was set right, nothing changed. Guy before me had rebuilt top end, TPS, T-BAP, ECM, Fuel injectors, Crank positioning sensor. I’ve checked out the connectors and wiring and didn’t see any issues. Please Help!!!
