Fuel is not getting through to engine and i changed the fuel pump but nothing

Electrically, you could also have a bad fuel pump relay, a bad fuse, or a burnt contact in your ignition switch. Mechanically, you may also have a blocked fuel filter a bad pump, or an open fuel pressure regulator.

I would check the fuel pump relay for power with someone helping cycle the key on and off. The pump only comes on for two seconds to fill the fuel rail. If you have power at the relay the switch is working and then you can check for function at the pump. If you have a repair manual of some kind check for the fuel pump power test lead location for the fuel pump. It should be under the hood somewhere near the drivers side firewall. You can put 12 volts to this terminal and run the pump by itself and be sure it's ok. If it runs and you don't get any fuel pressure you either have a blocked filter/line or a bad pump!

Good luck and be careful.

Did you change the fuel filter? Or maybe clogged injectors.
