Crusaders and Lisburn Distillery will have to do it all again in an Irish Cup quarter-final replay on Monday week after this Seaview stalemate.
In-form Aaron Boyd headed the Whites into the lead on 11 minutes.
However, Timmy Adamson levelled six minutes later with a close-range finish after a David McMaster cross.
Whites keeper Lee Windrum denied Adamson in the second half with Crues keeper Yohann Lacroix blocking a late Philip Simpson effort.
Boyd nodded the visitors into the lead as he connected powerfully with a Scott Davidson cross.
But the Crues were on terms within six minutes as Adamson maintained his scoring sequence in this year's Irish Cup.
After the break, Windrum made a superb full-length save to tip Adamson's drive out for a corner.
Jamie Mitchell and substitute Jordan Owens also missed Crusaders chances before French keeper Lacroix made a crucial late save for the home club to deny Simpson.
