Try debugging your script with print and printf, it's likely that will help finding the cause. Also, note that 7.0 in IsPlayerInRangeOfPoint actually not that far is, it's only 7 meters. It's barely two vehicles away from the center of the Pay&Spray.

Also note that you're sending the playerid in the timer, but then you're using SetVehiclePos with the playerid? I can guess that that will move the incorrect vehicle (or move no vehicle at all).
