Procedure; Human Factors; Company Policy
We were lined up and waiting then cleared for takeoff with only one engine operating. I advanced the thrust levers and checked the engine parameters and noticed the engine was not running. This was the First Officer's first trip off of IOE and I am somewhat new to the airplane and airport. The First Officer told me he was accustomed to single engine taxiing and receiving the delay engine start command. In the interest of safety I have been starting both engines after push. I feel it is better for me; at this point in my career to accomplish as much work as possible while stationary to have both pilots' heads up for taxi. We pushed off the gate and started engine 2. We received the wave off and I FIRMLY believe I commanded an engine 1 start. I failed to properly verify engine number one's operation. Then I was distracted with helping with frequencies and taxi instructions. After we taxied clear of the runway the First Officer stated he did not hear the delay engine start command. I do not understand why; if the First Officer knew the engine was not running; he let me proceed or why he did not mention the delay engine start procedure.
During routine taxi to Runway XXR; Captain neglected to call for a delayed engine start check. Still being a little overwhelmed at ZZZ (high mins; First Officer) I failed to recognize and prompt the Captain that we need to start engine Number 1. We performed a before takeoff checklist and were then cleared to line up and wait. Moments after being cleared for takeoff; just as the Captain was setting thrust; I noticed and announced we had no power on engine 1. We exited the runway at [Taxiway X]; informed Tower; started engine Number 1; and got back in line for takeoff; taking off 4 minutes later. We never accelerated past taxi speed; took the first right turn off; rest of trip uneventful.
EMB-145 Captain reported a cockpit miscommunication caused an engine not be started prior to takeoff and resulted in an aborted takeoff.
