Question
Q: i don't have any power on my fuse for the fuel pump to start. Don't know how it occured.

I replaced the distrbutor & conductor plate, I heard something like burn electric current then the car stop receiving power. Check the fuse and the fuse don't have power either. I also checked the fuse attached to the firewall & one clicks everytime i hit the ignination switch. is there anything that i can do to fit this.

Answer
the fuel pump fuse remains without battery power until you turn ON the ignition switch at which point the fuse will receive battery power for 2 seconds and the go back to reading no power.

once the engine starts the fuse will have battery voltage at all times.

As soon as you turn ON the ignition switch to start the engine a 2 second ONLY battery voltage signal is sent from the computer to the fuel pump relay and from the relay back to the fuel pump in the fuel tank. This runs the fuel pump for ONLY 2 seconds of which pressurizes the fuel system in preparation to start the engine.

Once the engine starts, The computer BYPASSES the fuel pump relay and  sends constant contionous battery voltage from the computer to the oil pressure switch of which is now CLOSED because the oil pressure is UP because the engine is running. Therefore the battery voltage flows thru the oil pressure switch back to the fuel pump to run the fuel pump constantly until you turn OFF the engine.
