layback40 referred to "...a PDF about the fuel system that shows a signal on a screen of a DBR scanner..." I don't know if DBR is a typo or not.
So I Googled "DBR scanner" and found a link that provided a name as Diagnostic Reader Box.
This is all new to me. It seems to be a big brother to the OBDII code reader that can gain reading and writing access to the Transmission and Body control modules. That link also mentioned a price of $6000. Whew - may as well be part of the Space Shuttle.

Hi Dean,
For some reason, unknown to me, my post has gone.
The scanner I referred to is what Chrysler/Jeep dealers use.
The dealer nearest to me quoted me $250 to do a full scan with their scanner.
Its more like a tablet than the small handheld scanners most of us use.
It will look at all modules, even the ABS one.
They do have a small handheld version they use in their workshop.
The PDF I mention is a training presentation.
IIRC it gave information about the pressure control solenoid under different conditions like WOT under load.
The CRO I have has allowed me to look at the pulse signals. I was something I was able to get on a long term loan.
The app that WW has helped you get will probably do all that is needed. I was going to try an app that uses the audio input of a smart phone but the CRO was handed to me first. I had used one previously decades ago at University.
The signal to the pressure control solenoid for mine looks fine, next I am going to look at the quantity one on the CP3.
Probably will look at the GP pulse signal as well.
I am not getting high enough signal from the rail pressure solenoid. I have replaced it & got a small increase in the signal.
As my background is in process control & this probably dictates my approach.
Will keep you guys posted on what I find.
