exup is'nt ypvs ! you have no sound to hear from your valve .....only fuel pump and only for 10 second, after key switching .

The EXUP uses the same style of servo as the YPVS, and goes through the same clean / calibrate cycle at startup. You SHOULD hear the servo when you turn on the key and kill switch.

Try grounding the top-middle pin on the 6-pin connector on the TCI. That's your safety input. and will prevent spark if it isn't happy.

Get yourself a manual - from what you've described, there's now way to fix it just using the Force. You need an actual schematic.http://fzronline.com/wiki/doku.php?id=fzr1000
