I am attempting to do a fuel pressure test on my vehicle listed above Limited. What is the stock fuel pressure spec range that fuel system should be within during the test?

Also, is only the idle pressure spec what needs to be checked or is there also a spec for the engine being off once fuel system is pressurized for test or any others that need to be checked?

Sure, here is a guide to help you with the test and I have provided the specs for the fuel pressure.

Fuel Pressure - 400 kpa +/- 34 kpa - 58 psi +/- 5 psi
