Re: I want to know wher the location of fuel pump relay...
It is in the under hood fuse box on the drivers side just in front of the brake master cylinder. if you look under the fuse box cover it will specify which one is the fuel pump relay.

The all in one PGM/fuel pump relay is bolted to the upper left hand side of the drivers foot well. It should be gray box with lots of wires coming out of it.

If you have already checked the relay and fuse then have someone bang on the fuel tank hard while you crank the engine, if it starts then you know you have a bad fuel pump.
No there is not, That is if you are referring to the fuel pump. You have an under hood fuse box in it you will have a fuse that protects the fuel pump circuit, a fuel pump relay, and wiring from there to the fuel pump which is located in the fuel tank. If you are not getting any fuel most likely the fuel pump has failed and will need replaced, Install a new fuel filter as well.
place fuel pressure gauge on fuel rail at designated location and chek press. this will eliminate f p , also check relay and fuses labeled "crank " let me know
