You don't need the engine running to check pressure.
Connect the gauge between the FD and the WUR, and disconnect the warm-up regulator. Pull the connector to the safety switch off the FD (if there is one), or bridge 30 to 87 on the fuel pump relay socket. Look for 5.6 bar system pressure, and 1.0-1.4 control pressure. Crack a fitting or two on the FD and see if you get some fuel. If not, turn the mixture screw clockwise until you see fuel start to come out.
Then reconnect wires to the WUR and you should see the control pressure come up to 3.4-3.8 bars in a couple of minutes.
If you are getting these values, and spark, the car should at least start and run. Leave the gauge on to see what happens to CP while it's running.
If you don't see these values, you need to find out why.

I had guages on it and was getting values like you said but I didn't disconnect WUR. How do you know which is system pressure and which is control pressure when connection to guage does not change. I had guage on and it would be like 1/2 bar then climb up and then drop down. I never removed the WUR connector. I put the guage on the injector line also and adjusted the air fuel screw just til the pressure started to build on gauge.
