Aircraft
Upon taking runway and cleared for take off; Captain transferred control to Copilot and advanced throttles and pushed TOGA levers upon call out for Set Take Off Thrust. Left engine did not advance any further while right engine advanced to takeoff power. Aircraft yawed to the left; Captain reclaimed control of aircraft and aborted take off. Copilot notified ZZZ Tower of aborted take off. Remained on runway for 2 minutes to examine left engine responsiveness. Engine was non responsive to thrust lever movement and determined aircraft was unfit to fly. Notified ATC that aircraft would be returning to gate. Left engine remained unresponsive the entire way back to gate. Returned aircraft to maintenance for troubleshooting.
After given clearance to takeoff on XXR; the Captain advanced the thrust levers and I called for 'Set standard thrust'; the aircraft began to yaw left.  I immediately hit the brakes and called for an aborted takeoff. The Captain resumed control of the airplane and I called for an aborted takeoff with ZZZ Tower. We asked for 2 minutes on the runway and began to trouble shoot the problem. We noticed that the left engine would not increase from idle no matter where the left thrust lever was placed.  We asked for taxi instruction back to the Company ramp and performed an After Takeoff checklist. The left engine would not spool up on takeoff. It remained at idle regardless of thrust lever position.Engine parameters were stabilized after start; showing a normal engine start. I need to make sure the Captain has spooled the engines up before calling for 'Set Standard/Max Thrust'. We may have been able to catch the malfunction a few seconds earlier.
Flight crew reported a rejected take off and a return to the gate after the #1 engine would not respond to thrust lever movement.
