On a 617, the crank should be at TDC. The pump has a wide part in the splines, and that needs to be lined up with the mark on pump body (11:00 O-clock I think?). The haynes manual (available at most auto stores) has a good procedure for installing the pump. The drip test should be done after the pump is installed. You can make a drip test tube from an old injection line (as shown in the haynes manual).
