On these TDCI's with that code the first port of call for me would be fuel filter/LP side, the second would be leak off
My scanner reported no codes
I thought I would break the scope out as I had a few mins spare and I did think it was leading me in the right or wrong direction!

What scanners that then ?
I had an "after market" scanner on a 54 Focus TDDI with SRS light on....no codes read.......Put IDS on = 1 code.I thought I would break the scope out as I had a few mins spare and I did think it was leading me in the right or wrong direction!
If you knew how to proof test the CR system it would have done,but you don't get HP without LP.
I understand the connection between LP and HP.
the ford dealer said there was nothing stored but did mention the filters were common, and it was blocked.
if the filter was blocked then surely it would of cut out from fuel starvation?....
From what I could see and understand the residual pressure that the rail sensor was seeing was dropping almost instantly when the engine was turned off
