I can not find the relay so i went to buy one to know what it looks like but i was told it does not have one, in the meen time i found a wiring diagram on the net from a parts store and it shows one, looks like the relay is wired from the coil and is mounted to the firewall, am i on the right track?

Your fuel pump is powered by the GREEN fuse link in the fuse link holder. If you have 2 terminals (both WHITE/BLACK wires) at the fuel pump relay that is HOT all the time (even with the key OFF) then this fuse link is OK. There are no other fuses to be concerned with.
There is also a "Fuel Pump Control Unit" located on the left rear quarter panel, behind the "B" pillar. (See Picture)
Check for a 15A Fuse labeled FUEL PUMP on the cabin Fuse Box located in the front seating area, driver side, under dash, behind kick panel.
The diagram shows the Main PCM relay controlling the Fuel Pump, but it wont hurt to check the cabin fuse box under hood, passenger side, rear side of strut tower, mounted in fuse/relay box on firewall

There are 2 fuses and a relay involved in this circuit but the lines that run power to the pump run partially exposed under the vehicle as well. Check the Interior Fuse, check the Fuse in the box under the hood and check to make sure you have voltage at the fuse under the hood. If these are good check for voltage on the wires going to the fuel pump at the fuel pump itself. You can do this with a multimeter and thumb tack. Use the thumb tack to puncture the insulation in the wires and test for voltage. If you don't have voltage there, start working your way back 12" at a time until you find the point where you have voltage to isolate the area of the break.
There will only be power for 2 to 3 seconds at the fuel pump after the key is turned to run position.Check the gray wire for power at the pump connector. Do you hear the fuel pump relay click at the front engine compartment when you turn the key to run position. The fuse should be under the hood,if not under the dash.
There is power at the fuel pump for aprox 3 seconds as soon as the ignition switch is turned on
then it does not get power again until the engine starts
so if you are checking the power at the pump you need to have someone else in the car to turn on the switch while you are looking at your meter , you have a relay under the hood under a plastic cover at the fire wall that controls the power to the pump .
