Help with fuel system

Asked by Jan 06, 2016 at 09:54 PM about the 2003 Nissan Frontier

Question type: Maintenance & Repair

My 2003 Nissan Frontier stopped getting gas to the fuel injectors.  We have replaced the fuel pump, the sending unit, the fuel filter and still do not have fuel coming to the injectors.  We have fuel past the filter, have tried to blow the lines. For some reason, it seems like the fuel is pumping back into the gas tank.  Can you tell me what might be the problem.

If you have fuel pressure at filter and have verified pressure,may need to check the fuel pressure regulator on fuel rail,may be bad.
