Synopsis
A320 flight crew reported executing two consecutive rejected takeoffs due to engine response issues during power up. The aircraft was taken out of service.
Narrative
When the throttles were moved forward for takeoff I got no response from the engines; so I continued to move the throttles slightly more foward still no response; I was getting no spool up at all. Then I felt a very slight buffeting and closed the throttles; and then got a momentary ECAM; that cleared itself as rapidly as it appeared; so we were unable to determine what it was. The takeoff was rejected and we taxied clear of the runway on to Taxiway 1 facing west. The Captain ran the engines up slightly and they responded normally; so we decided to try another takeoff. Moments later we got an ECAM high fuel temperature on the left outboard fuel tank (62)c which required us to turnoff #1 generator and shutdown #1 engine. Taxing back to the gate the Captain remarked that the #2 engine was very slow to respond to throttle input. The Captain wrote up both the rejected takeoff due to sluggish engine response and the fuel temp issue. The aircraft was taken out of service.Cause - Possibly the OAT which was 38c.
Second reporter narrative
First officer takeoff RWY XL. We were cleared for takeoff; First Officer advanced the thrust levers to spool up and stabilize the engines before setting Flex thrust. Both engines were very slow spooling up and when they finally spooled up and stabilized we got a master caution. It came and disappeared immediately and unfortunately neither of us saw what it was and there was no record in the current leg ECAM report. We rejected the takeoff at a speed less than 10 knots and cleared the runway on the first available taxiway. Once we were stopped on the taxiway; I called maintenance and let them know what happened. While sitting on the taxiway we got a master warning for hot fuel; followed the ECAM and shut the number one engine down and returned to the gate.If the engines would have spooled up and stabilized faster; I believe there wouldn't have been an issue. Only suggestion is the flight crews need to be aware if the engines don't spool up in a timely fashion; it needs to be written up in the AML.
