hi well i was driving and my car turned off and it didnt want to turn back on so i checked it out and i found out that the main relay was burned so i changed it then i replaced it.. the car turned on perfectly but ten minutes later the car turned off and it didnt want to turn back on so i realized that it has something to do with the electrical wiring but i dont know about car can u give me an advice should i buy a new fuel pump cuz maybe the other one is old or just check my wiring from the relay to the pump to see if theirs a short circuit....

If you turn the ignition to the "on" position, like if you wanted to just listen to the radio, listen for a quiet whirring noise from the fuel pump. (The fuel pump is located in the gas tank underneath the back seat behind the driver.) If you are in a quiet place it will be easy to hear this whirring. If there is not a whirring noise your fuel pump is probably shot (you would normally check the main relay first, but you just replaced that). If there is a whirring noise then your problem rests elsewhere.
