Hard to start, possible flooding

After the car has been driven and operating temperature has been reached it is hard to restart. Does not make any difference how long the car was driven. Runs good while being driven. The only way to get it restarted while it is still warm is to hold the gas pedal to the floor and try restarting. Takes several attempts while still holding pedal on floor. I understand that holding pedal to floor signals the computer to not inject gas.

History: 8/7/'18 Stopped running as if out of gas. Had fueled recently. Would not start. Had it towed to an independent garage. Installed new fuel pump. Drove car home approximately twenty miles. Next day it would not start. Tried to start several times. Acted as if the engine or starter was locked up.
