Fuel pump/fuel relay problem on 1990 Ford Mustang GT

I've got a 1990 mustang gt convertible.. Out of the blue my fuel pump stopped running. Got a new one..it started up ran great..then we shut the car off. Tried starting it again..fuel pump never cut on. This may be a vague question, but I just need some help figuring this one out

IT COULD BE THE FUEL RELAY SWITCH UNDER DRIVERS SEAT ALSO
Check your fuel filter and fuel line, a lot of the time the fuel pump will go out because many people often neglect fuel filter changes as part of maintenance. It will gunk up and cut off the fuel flow in the line.
