Problems with jetforce tsdi, urgent!

Hello, I have a problem with a jetforce tsdi. The scooter doesn’t want to start. If I want to start, you hear that he wants to light briefly and then you org and there’s nothing. Renewed were pistons, cylinders, compressor, spark plug. Spark is present. Screw the candle out she’s wet. In the error memory nothing is stored. I’ve also re-learned the throttle valve. I hope you can help me. Greet Alex
