Narrative:

Normal sequence up to push; cleared to start #2 engine. Turned packs off; momentarily went to flight start then moved switch to ground start; hacked clock. I am not sure when I added fuel as I usually do it at 25%N2 but today I cannot remember verifying that step but I know I did move the start lever to the idle detent; then saw egt increasing past normal indications; kept watching thinking there is no way it was going to go past red line. N2 was at 42%; never got any higher than that. Egt went through red line; and I should have cut it off but I was under the understanding it was supposed to cut off itself for a hot start. Looked up the reference for the auto cutoff last line reads 'current versions of eec software (7.B.Q and later) automatically turn off the ignition and shut off fuel to the engine for an impending hot start or stall.' not sure if this software was applicable to our jet today; and this certainly slowed my reaction time in getting the start lever to off. I was slow to cut off the start lever and did so once prompted by captain. Got to 841 degrees. Performed iai. Went to qrc then QRH. Back to gate and maintenance came out.

Title: B737 pilot crew reported a possible hung start and aborted start up.

Narrative: Normal sequence up to push; cleared to start #2 engine. Turned packs off; momentarily went to FLT start then moved switch to GND start; hacked clock. I am not sure when I added fuel as I usually do it at 25%N2 but today I cannot remember verifying that step but I know I did move the start lever to the idle detent; then saw EGT increasing past normal indications; kept watching thinking there is no way it was going to go past red line. N2 was at 42%; never got any higher than that. EGT went through red line; and I should have cut it off but I was under the understanding it was supposed to cut off itself for a hot start. Looked up the reference for the auto cutoff last line reads 'Current versions of EEC software (7.B.Q and later) automatically turn off the ignition and shut off fuel to the engine for an impending hot start or stall.' Not sure if this software was applicable to our jet today; and this certainly slowed my reaction time in getting the start lever to off. I was slow to cut off the start lever and did so once prompted by Captain. Got to 841 degrees. Performed IAI. Went to QRC then QRH. Back to gate and Maintenance came out.
