The timer is for one second but one second is longer than most think.
If longer than one second it may mean the caps are starting to go. In other words it is taking the clock a second or so to get going.
If the clock does not start then the fuel pumps will continue to run and the fuel injectors will not be grounded (or fired) by the computer.
