hpop pressure

[bearracecars]

hi guys
well the notices keeps telling i should post. so here it goes. check engine light came one a while back. i checked the codes and p2290 (injector control pressure to low) came up. i noticed no loss in power or anything odd. so i quessed it was the sensor or harness. got a new sensor but haven't installed it yet. so i reset the light, and it stayed off for awhile. then i noticed i kicked the light on when going up a hill. one was a long grade over a mountain pass and the other one was from a stop sign going up hill. the stop sign one i was hard on the accelerator with about 22 pounds of boost, but it didn't feel like i had any power and the light came one again. so now i'm wondering if i do have a low pressure problem.
is there a port to plum into to read the pressure? what should the pressure be running at?
thanks

knowing what year truck you have could be helpful.

you could have a bad icp...if you had a bad ipr or hpop youd
probably be seeing issues such has extended crank <to start> times
or it might even DIE while running down the road.

you can read more about the icp/ipr/hpop etc here -->

had to go and read a previous post...it is on page 11 in this section, "hpop psi"...anyway i had 3800 psi at WOT and 600 at idle....the psi number will fluctuate with throttle input....hope this helps
