Driving home and my '15 f350 6.7 flashes Reduced Engine Power, dies and will not start back. At first it was giving p2291 code. I noticed fuel wad under 1/4 tank, added fuel. Tried starting again, nothing. I have changed the fuel pressure/temp sensor, fuel filters, fuel lines from low pressure pump to rail,and low pressure filter housing. Need ideas!!!!
You said you changed it? Did you remove the VCV on the pump to check it? It’s possible I suppose. It’s also common for the wiring pigtail to fray right at the FRP sensor. You can also remove the fuel regulator at the back of the drivers side fuel rail to check for debris and or rust
