There seems no end to the Peterborough United scoring drought with Barry Fry's men now past seven hours of League and cup action without a goal.
But how they didn't manage to take just one of a hatful of chances against Crewe is sure to be the subject of a London Road inquest.
Unbeaten Alex were happy to soak up endless pressure to achieve a fifth successive clean sheet, but seldom showed any inclination to chase the game in search of all three points and registered only really telling effort from Neil Sorvel all afternoon.
Posh certainly asked the attacking questions in the first half playing Matthew Gill in front of the central defenders and regularly getting wing-backs Adam Newton and Gareth Jelleyman forward.
Newton twice brought saves from Clayton Ince and the Crewe goalkeeper was relieved to see Newton's header all but graze the bar from a swirling Jelleyman cross near the break.
Crewe could make little impression in attack with leading scorer Rodney Jack and the bustling Rob Hulse well marked and Posh continued to look the more dangerous side after the break with Jimmy Bullard again bringing the best from Ince after cleverly creating space for himself on the edge of the area.
Fry switched strikers for the last half hour with Jason Lee and Bradley Allen replaced by Andy Clarke and Francis Green although it was the wide men who looked the most dangerous, Newton letting fly from 25 yards to bring a spectacular one-handed save from Ince on 70 minutes.
Posh even committed themselves to another out and out striker with ex-Spurs man Neale Fenn on for Jelleyman inside the last quarter of an hour yet Crewe seemed happy with a point and when Jack did get a opening in the closing minutes his shot was nearer the corner flag than the target
