What should the fuel pressue be, and if low, how will I know that it is the pump and not the regulator?

55-60psi for the pressure. i thought the 02 or 03+ trucks had the returnless fuel system, ie regulator built into the fp assembly.

you can pull part of the intake off and spary starting fluid in the throttle body and see if it will start then. then you know it should be a fuel problem.

Fuel Pump ?
Here is an update ... I purchased a fuel pressure gauge and checked the pressue at the fuel rail ... it varied from 5 to 10 psi. I pulled the tank and removed the pump. I will pick up a new pump today and install.
Stay tuned ...

isn't it still under warranty?? An 07 shouldn't be having these types of problems yet.
