Story of the game
Sutton took the lead on the first corner of the game as Kizzi latched onto Robert Milsom's delivery and headed past Hartlepool goalkeeper Ben Kilip.
The hosts created their first chance as Lee Molyneux fizzed a low shot from the edge of the penalty area that came back off of the post.
The Yellow Army could have doubled the lead as Ajiboye seized on a loose pass and set up Donovan Wilson, whose touch allowed him to be crowded out as he tried to shoot.
Bryn Morris shot wide from the edge of the penalty area in a first half of little chances for Pools, but in the second, they were much the stronger side.
The first corner for Hartlepool came in the 51st minute and it produced the equalizer as the ball was worked to Zane Francis-Angol on the left and a glancing header by Morris hit Crawford, who made no mistake.
Hartlepool had most of the ball the remainder of the game, Morris sending one straight at Dean Bouzanis, who mishit a clearance, but Ben Goodliffe tracked back to clear from Crawford's effort.
In stoppage time, substitute Harry Beautyman got onto the end of a long throw by Milsom, but Kilip was able to collect as both teams were forced to settle for a point.
