One injector not pulsing on TNT 302s or rather not firing. There is continuity from ECU to the Injector, wiring in the harness looks good, wire voltage looks good what could be the issue? When i swap the two injectors the injector function well on the right side but when returned to its place not pulsing. 馃槳馃槳

Ecu knackered? Voltage could be permanently on on faulty cylinder instead of pulsing. Does the other coil work in the other position?

attach a 12v bulb to the injector wires coming from the ecu .. it should flash on and off when trying to start the bike , if not id say the return to ground through the ecu isn't working for some reason break in a wire hopefully
