@@JoshNieman-b9o I had a code for low fuel rail pressure and swapped the LP pump from the old engine and it was still saying it. I could hear the tank pump kicking on. In the diesel world the relief valves control the world, so I figured it has to be similar. Sure enough it was it.
Did your scanner show low side fuel pressure ?
