When I moved to P3d V5 in every airport the livery of service vehicles was gone I tried to reinstall the GSX it can't be fixed.

This is normal, and the reason has been clearly explained both in the P3D V5 announcement and the P3D V5 instruction thread as well, in this very section of the forum:

There are still some stability issues that must be fixed in the sim, so the addition of DX12 support will probably appear after the next Hotfix. But we don't have a firm date about it, because it's a very complex and delicate issue that can easily crash the sim, if not done and tested correctly.

Also when boarding or refueling I change the payload or fuel the GSX will no respond. 

Please clarify what do you mean with this.
