Narrative:

Aircraft type, ATR 42 scheduled departure from lihue, hi. 1) we were cleared to start #2 engine, after start we were asked and shutdown #2 engine to load more bags. 2) then we started #2 engine again, then the #1 engine. I was reading checklists and the captain responded appropriately. 3) at departure time it started to rain and the captain was anxious to pull away from the gate. I received the taxi clearance and we proceeded out to runway 3, we did a taxi check and held short of runway 3 (it was a short taxi) and I spent the whole time reading and doing checklist. We were waiting for the EFIS time countdown to finish. 4) an air carrier 737 was in line after us for takeoff. The EFIS check finished and the controller cleared us for takeoff. We repeated the clearance ran through the before takeoff checklist. The captain noticed a acw fault light on the #2 engine overhead panel. He applied some power and told me to tell tower we are taxiing off (at the first intersection) we taxied around to the runway 3 here again while the captain cycled the fault lights and switched off the propeller brake. 5) I think we taxied for takeoff the first time with the propeller brake engaged on the right engine, I wasn't aware of it at the time, but it seems to be the case, in our checklist it only states that the propeller brake is checked, it should of been off before taxi, I figured that out when the captain reached for the propeller brake after we were off the runway. 6) things happened quickly and the captain was complaining of lack of sleep. And mistakes were made with the checklists. The event was reported to the company and the FAA by the air carrier 737 pilot. An ongoing investigation is in progress.
