When revved in neutral throughout the rpm range the pressure is pretty steady within specs.


Thoughts???
not sure what to think on that. in spec on idle is a positive at least it shows that the injectors are getting correct pressure.
under spec. at key on test is the head scratcher. I believe the key on test is to check that the system is pressurizing properly for initial start up. (That is a guess on my part.)

You had not said anything about starting issues so maybe the low spec is not an issue????
