91 Honda Accord Ex Wont Start?

my 91 accord ex coupe 5spd has a starting problem i cannot figure out. sometimes it will start right up (seems liek after it has been driven). sometimes it will just keep cranking and not fire (playing with the gas seems to help) and sometimes the car will fire right up but stall as soon as i let off the key. also for the first minute or so the car will idle rough and rpms will jump around. if anyone has similar experience with anything like this please let me know.

Suggestion:

Check your fuel pump and fuel pump relay, they could be malfunctioning. Hope this help!
