Jim,

Let's start from the beginning so I could get a good feel of what you are doing with your CIS. On a cold engine measure the cold control, warm, and system pressures (use psi. for me). You don't need to unplug the electrical connection to the WUR. Test run the FP with the pressure gauge correctly installed. The instant the FP starts to run, use this initial pressure reading as your CCP. Allow the FP to run no more than 5 mins. and make sure you have a fully charged battery.

Record the control fuel pressures versus time (0, 1, 2, 3, and 4 mins.). The control fuel pressure may or not reached the WCP after 4 mins. Observe the gauge pressure reading is steady and not rising anymore. Close the shut off valve and measure the system pressure (psi.). Stop after 5 minutes.

Might as well include the Bosch number on your WUR and FD. The tests will show if your WUR and FD are in good working condition. BTW, what year is your 3.0 liter engine? Keep us posted.
