Before solving the two-way FSI make sure that individual participant works well. You can use representative load on system coupling boundary.
Also refer to this tutorial Reed Valve FSI Co-Simulation with Partial Setup Export from Workbench (Fluent-Mechanical) (ansys.com) and see if the settings and boundary condition are correctly defined.
