it could be... or it could be a loose wire anywhere between the VSS, PCM, and instrument cluster.

If it's not working at all (no movement) the simplest thing it could be is a blown fuse. Although that's only simple if you know why it blew. I accidentally shorted the back of my 91 cluster once and it blew the fuse that protected the speedo circuit.
I'm not sure what else might be on that fuse. Is anything else not working? The owners manual should tell you what is on each fuse but someone here proabaly knows exactly what fuse to check.Vic

my personal experience, (2001 mgm) maybe once a month when i start it up, my speedo (mine is the digital one though) doesnt kick in for a few mins, or not atoll. i don't care enough nor do i have the money to go digging around. so my advice is to leave it for a bit and see if it kicks back in.Comment

Have you got an obd scanner that will do live data? See if vehicle speed is being registered by the pcm.
