After winter storing my Paso 906, there is no sparks on plugs. Alle fuses are okay. My batteri is okay. My bike is made with Marelli ignition (original)

Please feel free to supply me with suggestions how to solve my problem.
First of all - I have the wiring diagram and a digital multimeter gauge.
I have checked that the safety switch is okay - it is, and the signal is present at pin no 6 on the Marelli box, when safety swich is set ON.
A friend suggests that the ignition pickup is failing....?
