If you have to pump accelerator alot before it will fire, you have a leak. If you loosen fuel inlet nut after engine is warmed up, you should get a "spray" of fuel, not a dribble. If you have a dribble, this would be a vac leak allowing fuel to drain back to pump.

Could be any of these: Bad fuel pump, blown fuse or broken wire (if you have an electric pump), dirty fuel filter, blocked fuel line, fuel line leaking, no gas in the tank.
