where can i find timing marks on vauxhall vivaro injector pump?

If it is a common rail system on yours the pump doesn`t need timed,only the crank and cam pulleys which I would mark with paint for references,if these don`t move,give the motor a couple of turns and they line up then you are ok.There is a tensioner tool for these but if you take note how far the tensioner pulley is from the bracket on the tensioner housing and get it roughly back there then you won`t be far off,adjusted with a 6mm bolt,nip up the pulley nut,remove the bolt,if you can twist the belt 90 degrees along the longest part of the belt then that shouldn`t be too far off.
