Hello, our Zündapp 125 ABS (Bj.2021) went out immediately in driving mode and no longer wants to start. Ignition spark is there, fuses are also intact. Since after various start attempts the spark plug remains dry, but the pump from fuel transports out of the tank, my guess is on a defective on the injection valve. Can someone tell me how to check the injection valve? (Expand and try to clean?) The resistance (injection valve) measured by me b ebears ~11,8 Ohm? The plug that is plugged on the injection valve has a voltage of approx. 0.5Volt. Greeting
