08 6.4 p0193 p0194 need help

[twinturbo6.42008]

I have a 2008 6.4 75xxx miles h&s all ******s just had new rocker arms and push rods put in about 1000 miles ago now the truck is throwing codes p0193 p0194 and surging or just stalling out. First time doing it was two days ago while pulling and 10k lbs excavator i know the codes have to do with the sensor but iam not sure where to start. Any help would be great thanks

Sounds like the fuel rail sensor is bad, or wiring under the valve cover is chaffing

It was the fuel pressure sensor and wiring harness. So for now its good to go time to sell
