West Ham's struggles at the foot of the table continued as they failed to break down Blackpool, who made 11 changes.
The hosts dominated the first half and were unlucky to be denied a penalty when Craig Cathcart appeared to use an arm to block Victor Obinna's volley.
Luis Boa Morte and Pablo Barrera wasted good chances and Carlton Cole hit the post as the Hammers continued to press.
But Blackpool's Marlon Harewood was guilty of the worst miss of all when he shot wide with the goal at his mercy.
Boos rang out around Upton Park at the final whistle but for a side lacking in confidence, West Ham's players produced plenty of endeavour in an entertaining encounter which lacked only a goal.
Both teams had a hatful of chances to grab a late winner but the defences held out and both managers had to be satisfied with a hard-earned point.
Defiant Holloway stands by changes
Most of the pre-match talk focused on Ian Holloway's selection policy after the Blackpool boss threatened to quit if he is punished for making 10 changes for the midweek game against Aston Villa.
He went one better this time by changing his entire starting line-up but often cut a frustrated figure on the touchline as his team carved out few opportunities in the first half, against a West Ham side without a win in their six previous league games.
In the first league meeting between the sides since 1971, long-range efforts by Elliott Grandin and Neil Eardley and a fine run by David Vaughan was all the Seasiders could offer.
All the pressure though was on the bottom-of-the-table hosts with midfielder Scott Parker demanding improvement and Kieron Dyer uttering the words "doomed" and "fear" in the build-up to the match.
Parker was a bright spark throughout but many of his team-mates looked edgy, wasting a number of opportunities in the final third of the pitch.
Frederic Piquionne nodded wide from a corner by Barrera - on for the injured Dyer after just 15 minutes and Hammers boss Avram Grant was rueing his luck when referee Kevin Friend failed to award a penalty after defender Cathcart slid in and blocked Obinna's volley with his arm.
Blackpool had to change their keeper at the interval with Ghanaian Richard Kingson replacing Matt Gilks and his first job was almost picking the ball out of the net as Portuguese midfielder Boa Morte latched on to a cute through-ball by Parker but shot narrowly wide of the right-hand post.
The game became an end-to-end spectacle with both teams sensing the three points could be theirs but chances went begging time and again.
The irrepressible Parker burst down the left and squared the ball for Barrera to shoot straight at Evatt's legs and Barrera was again involved as substitute Cole deflected a shot on to the post.
Holloway's men looked dangerous on the counter-attack and immediately after West Ham's flurry of chances, Gary Taylor-Fletcher blazed over.
Grant delighted with Hammers display
Harewood should have settled the match against his former club when a left-wing cross arrived at his feet less than six yards from goal but he only managed to send the ball back in the direction from which it had come and out for a goal-kick.
Despite that, Blackpool looked the most likely to snatch a late winner and Robert Green had to be alert to save Cathcart's volley from four yards.
The draw, however, was enough to give them hope of further progress in the weeks ahead, while Grant was left to ponder the possible ramifications of failing to achieve the seven points from four games demanded by co-owner David Sullivan earlier this month.
After a third successive draw, they can only reach six, even if they beat Liverpool at Anfield next Saturday.
