Changed the fuel filter.
Last night driving around it started popping a code for low rail pressure. (Used carista to pull/clear code)
It would do it if you got on it fairly hard.
So after searching and searching, there were a few common causes. 1. The HPFP going bad. (Which was a big problem with these, but most were failing before 40k miles) 2. The rail pressure sensor. 3. The rail pressure regulator. 4. Clogged filter. Etc. Oh also these have 3 fuel pumps. The one in the tank, the HPFP, and a Auxiliary fuel pump mounted by the filter. I started hearing a buzzing before the light tripped and it was coming from the aux pump area. (Before I knew it was a fuel pump. Lol) I guess it was kicking in.
Beings we just drove 12 Hours the night before. I was thinking fuel filter. My wife said she stopped at a questionable station. (I was wore out and napping)
So today picked up a filter and some diesel klean, and planned to do some investigating.
Ended up just being the filter. Thing was bad. I'll get a pic uploaded.
I thought we had it changed not long ago. But I guess it's been awhile.
