Pakistan captain Babar Azam won the toss and elected to field in the second one-day international against England at Lord's on Saturday.
Rain delayed the scheduled 11:00 am (1000 GMT start) by 90 minutes, with the match reduced to 47 overs per side from the standard 50.
England stand-in captain Ben Stokes was winning his 100th ODI cap in the first match at this level at Lord's since he starred in a dramatic 2019 World Cup final win against New Zealand decided by a Super Over.
Both teams were unchanged following England's nine-wicket win in the first of a three-match series at Cardiff on Thursday.
England, the reigning 50-over world champions, had to select a completely new squad days before the start of this series after a Covid-19 outbreak among their original party.
Yet a totally changed XI, captained by the fit-again Stokes and featuring five debutants, thrashed Pakistan at Cardiff's Sophia Gardens, with only 67.1 overs of a scheduled 100 bowled.
Saturday's match at the home of cricket was the first in England to operate at full capacity since the pandemic.
