Is timing the only reason of Blanchard Kahn conditions fail

In 9 out of 10 cases, the timing is the reason. The less common reasons are wrong parameter values and general mistakes in the equations.

The steady state is unlikely to be the reason unless there are multiple steady states. After all, your steady state values solve the entered equations. That being said, you are using a linearized model, so the steady state values of the nonlinear model turn up as parameters. Wrong computations here fall under the parameter value issue.
