Good diagnostic video on the loose Direct Injection pressure sensor problems
Same thing is happening on the 2IS series as we speak. The 06 - 08 crowd. That said they are replacing the sensor.
Like the video, unplugging the sensor allows the car to start.
Good find.
Note to those trying to troubleshoot (TS) this: Using engine ground and the data wire, not the 5v supply wire, one could TS this with a volt meter by back probing the data wire and reading the voltage. Engine off the pressure leaks down and with the key on one might see 0.5v. When running expect something north of 2.5v and to increase as RPM goes up.
Hint back probe is to use a very small stiff pointed probe to shove through the moisture proof connector. Again, us common engine ground for ground.
