Narrative:
After initial pushback from gate; could not start either engine due to failed APU bleed. Returned to gate and APU bleed MEL applied. Notified by ATC that airport would hard close at midnight local time. Pushed back second time with only 15 minutes to airport curfew and airstart to start left engine. After pushback; APU off; crossbleed start to get right engine going. Cleared for immediate takeoff due to time constraint of airport closure. On takeoff roll EICAS message appeared for both left and right engine bleed. Captain aborted T/O at 60 KIAS. Cleared runway and stopped to assess possible reasons for bleed issue. Realized failure to complete after start check before and this caused pack switches to be left in off position. Decided to initiate second T/O attempt thinking that pack switch position may have caused bleed issue. On second T/O attempt EICAS gave same message only for right engine bleed. Aborted T/O less than 80 KIAS and cleared runway. Returned to gate for maintenance and at this time airfield had just closed for curfew. Upon arrival at gate; noticed that isolation valve may have been in the wrong position for takeoff which could have been caused by previous after start checklist mistake. At this point time constraint had become an adverse and negative factor in events leading up to this. Possible aircraft malfunctions and one maintenance issue compounded with another leaves open too many questions to determine causes of bleed event. Left a/C with maintenance to determine fix.time constraint due to airport hard curfew. Aircraft malfunctions. Possible crew checklist error. Feeling rushed to attempt to get airborne before airfield curfew after already returning to gate for APU bleed malfunction. Neglected to run after start checklist after crossbleed start and abnormal takeoff pack switch positions or isolation valve switch position could have affected engine bleed issue to occur on takeoff. That said; being unsure of switch position; the aircraft presented an abnormal that caused rejected takeoff decision. ACARS would not init on second pushback and init message remained on mcdu forcing extra time lost to message operations and clear up issue. Too many adverse factors led to errors.never allow time constraint to pressure me or other crewmember to rush our duties. Make sure to run each checklist every time.

Title: A B757 crew failed to complete the after start check following a ground air start and the cross bleed start because of an inoperative APU air. They then rejected two takeoffs because the bleed air panel was not set correctly; and after the airport closed the flight was canceled.
Narrative: After initial pushback from gate; could not start either engine due to failed APU bleed. Returned to gate and APU bleed MEL applied. Notified by ATC that airport would hard close at midnight local time. Pushed back second time with only 15 minutes to airport curfew and airstart to start Left Engine. After pushback; APU off; crossbleed start to get Right Engine going. Cleared for immediate takeoff due to time constraint of airport closure. On takeoff roll EICAS message appeared for both L and R ENG BLEED. Captain aborted T/O at 60 KIAS. Cleared runway and stopped to assess possible reasons for BLEED issue. Realized failure to complete after start check before and this caused PACK switches to be left in OFF position. Decided to initiate second T/O attempt thinking that PACK switch position may have caused BLEED issue. On second T/O attempt EICAS gave same message only for R ENG BLEED. Aborted T/O less than 80 KIAS and cleared runway. Returned to gate for maintenance and at this time airfield had just closed for curfew. Upon arrival at gate; noticed that ISOLATION VALVE may have been in the wrong position for takeoff which could have been caused by previous after start checklist mistake. At this point time constraint had become an adverse and negative factor in events leading up to this. Possible aircraft malfunctions and one maintenance issue compounded with another leaves open too many questions to determine causes of BLEED event. Left A/C with maintenance to determine fix.Time constraint due to airport hard curfew. Aircraft malfunctions. Possible crew checklist error. Feeling rushed to attempt to get airborne before airfield curfew after already returning to gate for APU BLEED malfunction. Neglected to run after start checklist after crossbleed start and abnormal takeoff PACK switch positions or ISOLATION VALVE switch position could have affected ENG BLEED issue to occur on takeoff. That said; being unsure of switch position; the aircraft presented an abnormal that caused rejected takeoff decision. ACARS would not INIT on second pushback and INIT message remained on MCDU forcing extra time lost to message OPS and clear up issue. Too many adverse factors led to errors.NEVER allow time constraint to pressure me or other crewmember to rush our duties. Make sure to run each checklist every time.
