I need to see if the low side pressure is bleeding off, but right now it seems that my scanner cannot read the low side fuel pressure value. Can anyone tell me if they have in fact read live data for this pressure with a scanner? I want to know that it is actually possible to see as i work through the issue with the scanner company. I need some evidence so i can be sure it is possible when I tell them i should be able to read that value on this particular vehicle.

thanks!
