the computer turns it on for 2 seconds to prime the system. it should not run again till the motor cranks and starts.
does it have spark??

Yes it has a spark. Is the computer the only thing that tells the pump to run 2 sec. or is there something else? When it's cold it runs the pump for 5to10 min. then it might shut off then the car will start.
