1997 Honda Civic having trouble starting? - 1

I have a 1997 Honda Civic automatic that is having trouble starting. I recently got a new car and unfortunately neglected my Civic. It has say for a month now and when I tried to start it today it would turnover but not start. I put some gas in it but it didn't change anything. It doesn't sound really rough or anything, it just won't start. This happened a couple years ago and when my mechanic came to look at it he did something under the hood, like pressing a choke or something, to help it start. I can't remember what he did and I have since moved too far to use him now. Does anyone have any ideas or know what it was he might have done to help it start?

You could try squirting a little starting fluid in the intake duct. When starting have the gas pedal halfway on. Or full on. Listen for the fuel pump when turning the key on before starting.
