ANo, a negative value of intercept does not suggest that the regression line provides poor“poor fit to the datadata”. Why not? Because the intercept is not a measure of fit for a regression. It is a value that represents one element of the model, not the quality of the fit.

The goodness of fit of a statistical model describes how well it fits a set of observations. Measures of goodness of fit typically summarize the discrepancy between observed values and the values expected under the model in question. WP:EN s.v. Goodness of fit

[...] y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. WP:EN s.v. y-intercept

See KDG's answer for an illustration.
