Hi Brian, code search revealed P0344 which points straight at the CPS as the issue.

I haven't checked the ICP and check for oil. My HPOP has only the slightest of leaks but I guess it doesn't take much if the leak is in the right place.

I tried a couple of times a few minutes apart on the verge. No luck.

Fuel pressure gauge still reading normal - just over 60 psi (4 bars) pressure.
