No fuel pressure can be a pump, plugged fuel filter, damaged or crushed steel fuel line. As far as the issue, even if you are getting fuel to the rail, it could be too weak to run the vehicle. That is why I recommend checking pressure. That is the ONLY way I can be sure it is the pump. Also, if you have fuel to the rail, the relay sounds fine. The only other thing that could be checked is to see if the injectors are getting power.
As far as the fuel pressure test, if there is no schrader valve on the rail, you have to get a T and check the pressure at another location. Often times, it is checked right at the filter.
Please understand, not being there and not knowing the pump pressure doesn't assure me that the pump is the issue. Without following a few diagnosis procedures, we are guessing.
