Elaborate on this. By fire you mean spark in the engine? What is the problem exactly? Your wording is a bit confusing.

Car will not run because of lack of fuel to engine. WhenI hot wire the fuel pump I get gas to the engine but the car still will not start. There is no fire to the pump when I attempt to start engine using the ignition switch. I recently replaced fuel pump and regular and also fuel pressure regular. Is there a some form of relay between the ignition and gas pump?

Yes. There should be a fuel pump relay. Also check your fuses, there may even be a fuse for the pump
