Burnley came back from behind to hold West Ham at the London Stadium and remain unbeaten in their first three Premier League games.
The hosts dominated, with both Michail Antonio and Marko Arnautovic going close and the Clarets goalkeeper Tom Heaton twice denying Sakho and Obiang.
Substitute Will Hughes had Burnley’s best first-half chance but headed wide.
But Pope, a summer signing from Bristol City, made his first league start and was unsighted only once as West Ham struggled in the first half.
The 19-year-old did not have to make a save until nine minutes from time, when Jack Cork’s shot from a corner was turned behind for a corner.
Chelsea are the only unbeaten side in the top flight, having won all four of their games.
After their opening two outings, West Ham have a record of one win and two draws from three games, while Burnley have won all three of their league matches to sit top of the Championship table.
Burnley’s performance had a familiar feel to it, as a defence, strong at home, was shaky on the road as Rob Green marshalled the Hammers.
A worrying moment for West Ham came as Robert Snodgrass tried a brilliant chip from midfield to find the far corner but Heaton was able to make the save.
But a theme of their opening three matches was a lack of fluency, which came with good reason as the Hammers lacked a cutting edge in the first half and were unable to convert the chances they created.
Burnley, particularly in the first half, rarely ventured upfield, opting for a dogged, defensive approach.
They were eventually rewarded for some first-half resilience on the stroke of half-time.

New Republic of Ireland boss Martin O’Neill was in attendance to watch his forward partner Sam Vokes, and Vokes was unable to carve out opportunities for the Clarets in the first half as neither he nor Jack Cork could get on the end of a James Tarkowski cross.
However, a second-half change in the shape of the team sparked a revival, with Aaron Lennon replacing Lennon and Vokes going close again as a prod into the bottom corner was tipped over by Green.
It was not until the introduction of Tyrone Mings and Jack Cork in the second half that Burnley pressed forward and created opportunities to win it, a chance that could easily have gone begging as Hughes headed wide.
The departure of Vokes did look to benefit the two youthful substitutes and Mings helped set up Tom Heaton for a late save from Jose Fonte.
But the result was a struggle for the hosts, who were perhaps soft in the first half but showed their fight in the second to secure three points after a difficult start to the season.

‘Always knew we could do it’ – manager reaction
West Ham manager Slaven Bilic: “They don’t give you many chances in the way we play, you have to be perfect against them.
“Our midfielders didn’t play to their standards and they changed at half-time and their response was very good. Burnley defended well and we couldn’t penetrate.
“Sometimes it is difficult to win against teams like this in this fashion but as long as you can manage to hold the ball and create chances you can always win.
“We are working hard to improve and always know we can do it and it is only a matter of time before we can start scoring goals.”
Burnley manager Sean Dyche: “We are not doing anything too great, we are not working that hard, but we are fighting, scrapping, playing in different formations and we are creating chances.
“It was a good away game for us and everyone’s improving, Jack Cork, Robbie Brady, Johann Berg Gudmundsson, all of them, we are all progressing and it is too early to write anyone off.”
