A 1-0 victory over visiting Medeama of Ghana in the final round will take the North Africans through on the head-to-head rule despite the goal drought.
But the North Africans forced a 0-0 draw at Medeama and will jump from third to second in the standings if they collect maximum points at home.
"We will fight with all our power to win the last group game," promised Bejaia coach and former Algeria defender Nacer Sandjak.
"Losing at Young Africans was an unexpected setback and we have no option but to go all out against Medeama and achieve victory."
Medeama moved three points above Bejaia with a thrilling 3-2 home victory over group leaders TP Mazembe of the Democratic Republic of Congo this month.
Kwesi Donsu snatched the winner five minutes into stoppage time after one of the most entertaining matches in the 13-year history of the second-tier African club competition.
"I pray that we can repeat that performance against Bejaia," said coach Prince Owusu, a mid-year appointment when Swede Tom Strand abandoned the squad after a defeat in South Africa.
"Such is the calibre of the footballers at Mazembe that I call them 'Africa United'. They came to beat us, but we shocked them.
"We have had a tough CAF campaign with many off-pitch problems -- especially a lack of funds for travelling -- but extremely hard work has taken us within sight of the semi-finals."
Mazembe, whose squad includes stars from DR Congo, Ghana, Ivory Coast, Mali, Tanzania and Zambia, need one point against visiting Young Africans to be certain of topping the final standings.
Former winners FUS Rabat of Morocco and defending champions Etoile Sahel of Tunisia have qualified for the semi-finals from Group B.
They meet in Rabat and a draw will keep 2010 champions FUS one point above 2006 and 2015 winners Etoile, assure them of first place, and a likely semi-final against Bejaia or Medeama.
Kawkab Marrakech of Morocco host bottom-of-the-table Al Ahly Tripoli of Libya on Wednesday in the remaining fixture with only pride at stake.
