There is nothing else between the fuel rail and the filter/pressure regulator.

When I turn on the ignition, the pump kicks on the fuel rail pressures up and the pump kicks off causing the pressure to drop at the gage. On the other side there is a line to the fuel rail and another line to the vent. The fuel filter/pressure regulator has a line from the pump and a return line on one side. I don't see any fuel leaking or hear any pressure loss. The fuel pressure regulator is working fine when the engine runs. There is a new fuel pump and a new fuel filter/pressure regulator. I have provided accurate help and appears I have helped you to isolate the problem, so could you please rate my help for com as 'HELPFUL', It is how I'm compensated for my time. You definitely have a defective fuel pump, the pressure should stay within 5 PSI of the running pressure after the engine is shut down for at least 24 hours, also the running pressure is well below the factory specification, so if you change out the in-tank fuel pump I am sure you will cure the problems you have. Do you have any idea on what the issue might might. I can't find any vacuum leaks and I get fuel to the injector rail. The fuel filter/fuel pressure regulator is new and the spark plugs are new. It is starting difficult and sometimes sputtering after it starts. I have been told it might be an inlet temperature sensor and that the sensor might have to be replaced/calibrated with dealer software.Īny other ideas or things I can check.
