Narrative:
We departed the gate and were cleared to taxi. I called for the taxi check. I assumed my first officer (first officer) had started both engines since my attention and focus was outside taxiing the airplane. We did run the checklist; but I never focused on the engine instruments.as we approached the end of the runway we were cleared for takeoff; completed the before takeoff checklist and I aligned the airplane with the centerline and gave control to the first officer. He advanced the thrust levers I'm guessing about 1/4 of the way towards the thrust set position when the nose immediately yawed to the right. He immediately retarded the thrust levers. We rolled less than 100 feet. Simultaneously we lost intercom between us. I took control of the airplane and told the tower we had a problem and needed to taxi clear. The tower cancelled our takeoff clearance; and we exited the runway. We sorted out our com problem; started the number 2 engine; re-ran the checklists and departed normally.I incorrectly assumed that the number 2 engine was running when I called for the taxi checklist.add both engines running to the before takeoff checklist; as it is on the emb 145. I now know why it's there.

Title: EMB-175 flight crew reported that due to distractions and fatigue they began the takeoff roll with only one engine running.
Narrative: We departed the gate and were cleared to taxi. I called for the taxi check. I assumed my First Officer (FO) had started both engines since my attention and focus was outside taxiing the airplane. We did run the checklist; but I never focused on the engine instruments.As we approached the end of the runway we were cleared for takeoff; completed the before takeoff checklist and I aligned the airplane with the centerline and gave control to the FO. He advanced the thrust levers I'm guessing about 1/4 of the way towards the thrust set position when the nose immediately yawed to the right. He immediately retarded the thrust levers. We rolled less than 100 feet. Simultaneously we lost intercom between us. I took control of the airplane and told the tower we had a problem and needed to taxi clear. The tower cancelled our takeoff clearance; and we exited the runway.
