In a campaign where Pompey went on to achieve promotion from League Two, Carlisle frustrated Cook and co side on the opening day, despite the visitors playing with 10 men for over an hour - forcing debutant Carl Baker to rescue a point.
A fine debut from summer signing Kyle Bennett got Pompey off to a flying start as he added to a Gareth Evans opener with a second-half brace - including a stunning strike from 25 yards.
Trailing from a Craig Woodman first-half goal, Pompey peppered the Exeter goalmouth in the second period with Ryan Bird brilliantly denied twice before Jed Wallace levelled with just over 15 minutes remaining.
In front of a record attendance for League Two, a Patrick Agyemang opener proved nothing more than a brief piece of excitement with Oxford hitting the 10-man hosts for four after Johnny Ertl saw red.
Administration-hit Pompey fielded a team of debutants after a turbulent summer. It was remarkable the hosts got anything out the game but did with Izale McLeod on the scoresheet.
A 92nd-minute equaliser from debutant Luke Varney earned the visitors a point. That season, in February 2012, Pompey were deducted 10 points for going into administration - which cost them their Championship status.
Pompey began their first Championship season in seven years with a defeat after two goals from Freddy Eastwood - his first coming as early as the fourth minute.
A summer heaped with turmoil failed to rub off in-time for the start of the term. Pompey left their shooting boots at home with just one of their 15 shots directed on target as Zamora handed Fulham victory with a fortuitous goal.
Fresh from their FA Cup success, Pompey were brought back down to earth by a rampant Chelsea under new boss Luiz Felipe Scolari. Joe Cole, Michael Ballack, Deco and Frank Lampard found the scoresheet.
An 83st-minute strike from John Utaka briefly had Pompey in the driving seat for an opening day victory at newly-promoted Derby, only for Andy Todd to equalise less than a minute later.
Long live Kanu! His debut had everything. From his two goals to a penalty miss - which denied the Nigerian his hat-trick against a Blackburn side who ended the game with nine men. Svetoslav Todorov also scored his first goal.
A future Pompey player in Jermain Defoe netted, coupled with an own goal from Andy Griffin. The 2-0 scoreline was the Blues first-ever Premier League opening day defeat.
A David Unsworth penalty cancelled out a Robbie Savage opener for Birmingham. The spot-kick was awarded when Stan Lazaridis was adjudged to have pushed Steve Stone.
