However, with some trips comming up I needed to get this sorted and make sure she is reliable. I changed the Fuel Rail pressure sensor, so change, and out of interest the Cam sensor... Still the same. So the only other thing related to Fuel Pressure was the "Pressure Regulator" sensor on the end of the engine Pump (Or fuel rail pressuriser pump)
However, invetween changing the Rail pressure sensor I then developed a random cutting out DEAD FLAT problem.. Only be pulling over leaving the key off for a moment and then restarting she would go after a god few turns..
Tonight I changed the Pressure regulator sensor, and this solved the starting issue, and allows a smoother idle and better starting. However, the cutting out was still there.
There was only one thing for it... NO, you've NOT guessed it, its NOT the fuel tank low lift pump! ........

The TUNING BOX!
I disconnected the Tuninng box after a couple of runs down the road with Parameter Readings on the LExia. When the Fuel pressure went to 900psi and above it cut out...
Normal service has resumed, but Ive not looked into the box to see why this has happend all of a sudden.
