My GPS is not working, not giving me pace on bike or run. Any ideas?
Do a hard reset.
OP–I’d call Timex. I use the Timex Run Trainer and love it. I had a problem figuring it out at first= called Timex and talked to a real person within minutes == operator error fixed 
Had another question about the chest strap==called Timex and recieved a free new chest strap within a few days.
Hope this helps.

I agree with the other guy - do a hard reset and then turn on the gpS sensor and let it sit outside for ten minutes or so until it gets a good lock. I have the Timex Ironman Run Trainer and love it. Its performed flawlessly and is very accurate. Good luck!
