I ran it for 1400 rpm for 7 minutes after engine temp reached 70, then returned to idle. The pump turned on for a few seconds and then stopped.
I then repeated the 1400 rpm, returned to idle but this time it didn't turn on.
The next day I did the same thing, the pump turned on the first time but not the second time.
Is it necessary for the pump to turn on the second time I run at 1400 rpm, and return to idle?

seconday air is the hard one. start cold engine run at 1400 rpm for 7 minutes after eng tem has past 70 deg then let idle for 6 seconds then turn ignition off for 10 seconds then repeat
after the 7 minute high rpm when you return to idle you should hear the pump turn on
good luck
