car shakes only on startup

been noticing that the car shakes for about 1 sec on startup. no real problem starting up, idle is fine, it's just for one second that hard shakes noticeably, then everything is fine. curious why...it's an old engine, 110k miles...

I experienced that happen on my other car. It is fuel pump.
