Summary:A method for operating a fuel injection device, particularly of a motor vehicle. The fuel injection device is provided with an injection valve which has a piezoelectric element. In using the method, the piezoelectric element is activated in such a way that the injection valve goes over into an opened state. During the activation, an electrical voltage is ascertained and/or prespecified at the piezoelectric element and/or an electrical current is ascertained and/or specified via the piezoelectric element. From the path of the voltage and/or from the path of the current one may infer the point in time of opening of the injection valve.
