'96 sunfire hard starting

Hello, I'm new to all this but here is my problem. I have a '96 sunfire 2.2L and it only starts if you hold the gas pedal to the floor and crank it over and over. once it is started it seems to run fine but just won't start easily. The car recently overheated due to a bad water pump. Replaced the pump but still the same thing. Any ideas would help.

Thank You
