Narrative:

It was the second day ever to fly together and the first flight for both of us in the maximum. Normal pushback. We received impending hot start on number 2 engine with auto shutdown. My attention was totally outside the aircraft as I was in the process of clearing the ground crew off. My attention was drawn back inside to see the white flashing box around the egt with the motor rolling back. At the time; the first officer (first officer) had no idea what may have caused it; so we ran appropriate QRH items for a suspected malfunction; started number 1 engine; and taxied back to the gate; making a logbook write-up; and calling maintenance. Having time to discuss what may have happened; looking through numerous publication sources; and sleeping on it; the first officer is now sure that he prematurely isolated/ventilated just momentarily; but long enough to steal the air source causing an incomplete and auto aborted start. Despite being patient and pre-briefing that we would not rush our first maximum experience in any way; anxiousness over the newness and the longer start process must have still affected our pacing. The isolation switch to isolate and the pack switch to on before engine rollback obviously caused the engine to shut down.more training would be great; and hands-on training would certainly have been beneficial. Still; we felt prepared; but the hype of the new aircraft with the unfamiliar pacing caused an unfortunate situation.

Title: B737 Max flight crew reported that an Auto Shutdown of the Number Two engine on engine start was probably due to the First Officer activating the Isolation switch and the Pack switch during the start.

Narrative: It was the second day ever to fly together and the first flight for both of us in the MAX. Normal pushback. We received Impending Hot Start on Number 2 engine with auto shutdown. My attention was totally outside the aircraft as I was in the process of clearing the Ground Crew off. My attention was drawn back inside to see the white flashing box around the EGT with the motor rolling back. At the time; the F/O (First Officer) had no idea what may have caused it; so we ran appropriate QRH items for a suspected malfunction; started number 1 engine; and taxied back to the gate; making a logbook write-up; and calling Maintenance. Having time to discuss what may have happened; looking through numerous publication sources; and sleeping on it; the F/O is now sure that he prematurely isolated/ventilated just momentarily; but long enough to steal the air source causing an incomplete and auto aborted start. Despite being patient and pre-briefing that we would not rush our first MAX experience in any way; anxiousness over the newness and the longer start process must have still affected our pacing. The Isolation switch to Isolate and the Pack switch to ON before engine rollback obviously caused the engine to shut down.More training would be great; and hands-on training would certainly have been beneficial. Still; we felt prepared; but the hype of the new aircraft with the unfamiliar pacing caused an unfortunate situation.
