It was in the works after Full Throttle's success, but was cancelled. I don't know the reasons.

There was actually more than one attempt at a sequel (Payback, Hell on Wheels) which were mostly "cash ins" outsourced by LucasArts and focused on more of the action-y stuff (FPS were just becoming the overriding rage in games) rather than the story telling. Tim Schafer, of course, moved on to Grim Fandango was not involved in the sequel attempts.

New rumors are that Tim himself is considering ideas for a Full Throttle 2 once they finishing remastering Full Throttle, but take those rumors with a giant grain of salt.

One entry way into the giant rabbit hole of old Full Throttle 2 news:

I'd love to see a new Full Throttle, but it would be sad to hear a new voice for Ben, who died not long after the original was released.
