Welp I’ve looked everywhere trying to find a video or tutorial on how to change out the fuel rail pressure sensor on my 2011 lml duramax. It’s currently throwing code P0087-fuel rail low pressure, I also got code P0191-Fuel rail pressure sensor performance it will only start off starting fluid and will run and drive fan afterwards. If anyone knows or can guide me in the direction to where the sensor is located I would greatly appreciate it and how to change it out and how hard it is. I was told there may be 2 locations where it could be found so I’m lost on where to start.

I’m currently trying to rip it out as we speak and it’s kind of a pig, my truck won’t start unless it’s on starting fluid and I’m wondering if it’s this if not this I think it’s the CP four but I’m not sure
