Burnley still can't buy a win but at least restored some pride to Turf Moor as they shared the points with promotion-chasing West Ham in a pulsating shoot-out in the sun.
First-half goals from Marvin Bartley and Martin Paterson looked set to earn the Clarets a double over the Hammers and a first success since beating Barnsley seven games ago.
But with four successive draws behind them the Irons, unbeaten in ten games, are a coupon banker and duly hit back with two goals in as many minutes mid-way through the second half through Kevin Nolan and James Tomkins.
The promotion hopefuls could then have won it as Burnley were left hanging on at the end, bar a late half-chance for substitute Charlie Austin.
But despite the disappointment of letting a winning position slip, Eddie Howe's men can take solace from a fully committed and inventive performance which helped erase the memory of their mid-week surrender at Ipswich.
Any thoughts that Burnley might just be seeing out time on their season were dismissed in a breathless first half in which the fully committed Clarets snapped out of their recent lethargic run.
Marvin Bartley fires the Clarets ahead
West Ham played their part in an incident-packed opening 45 minutes but it was Burnley who took their chances in a morale-boosting performance which ultimately came up just short.
England international Carlton Cole was less clinical as he passed up two early opportunites, the best when he rounded Clarets' keeper Lee Grant from Nolan's through-ball but was unable to hit the target from a diminishing angle.
And with 25 minutes gone Bartley showed him how it should be done.
The midfielder had scored only twice before for the Clarets but showed great composure to jink his way past Tomkins and slide the ball past Robert Green after Paterson's clever little flick had played him in.
It looked as though the lead had lasted less than 60 seconds as Nolan quickly headed in at the other end.
Martin Paterson makes it 2-0
But the Hammers' skipper was judged to have pushed Bartley by referee Mark Haywood, who finally managed to curtail the visitors' celebrations.
The Clarets' goal led a charmed life as Cole bundled the ball against a post and Nolan's follow-up was blocked on the line by Grant as Burnley kept scrapping for their lives.
And nine minutes before the break they doubled their lead. Paterson, shouldering the striking burden in the absence of injured top scorer Jay Rodriguez as one of four changes Howe made to the side that lost at Portman Road, had headed one early chance wide.
But this time the Northern Ireland international was at his predatory best as he timed a run perfectly to ghost in behind James Collins and steer a lovely cross from Ben Mee past Green to claim his first goal since the turn of the year.
Typical of a full-blooded affair the Hammers countered with Jack Collison forcing Grant to tip over his scorching 40-yarder, while Matt Taylor almost capitalised on confusion in the penalty area to poke his side back into contention.
Danny Ings beats Joey O'Brien
But it was the Clarets who were only inches away from going into half-time three up as Ross Wallace's inswinging cross eluded everyone in the box and cannoned against the foot of a post with Green beaten.
With the Hammers desperate for points to bolster their fading promotion push, boss Sam Allardyce dipped into his vast attacking armoury to make a double change at the start of the second half with Nicky Maynard and Sam Baldock on for Taylor and the mis-firing Cole.
Again, though, it was the Clarets who provided the greater threat as David Edgar produced a flash of brilliance in the box not matched by his attempted finish and Paterson fired wastefully over.
Inevitably there were chances at the other end as West Ham tried to force a fightback and George McCartney was almost an unlikely scorer as he wriggled free to get in a low shot which Grant saved.
And just as the Clarets looked to have left the Hammers short of ideas, Nolan popped up to turn the tide.
Just as he had at Upton Park in December, the former Bolton midfielder lobbed home after getting between Grant and Michael Duff to meet a Gary O'Neil through-ball after Duff had mis-judged the bounce and within two minutes the Irons were level.
Having defended so well, Burnley failed to deal with a Mark Noble free-kick and Tomkins pounced to side-foot home and set up a nervy finish.
Almost immediately Maynard got round the back to fire in a low cross which was scrambled away as Nolan waited to strike and then in the dying minutes the Hammers had a hat-trick of chances to win it.
Substitute John Carew was heavily involved and could have nicked the glory himself, but Baldock was the major culprit in letting two more points slip for his side as he fired wide from Carew's knock-down and then failed to beat Grant as the Clarets' keeper saved the day and a share of the spoils for the Clarets.
