[QUOTE="ckrueg, post: 1431626, member: 12403"] So my parents borrowed my old 6.4 for a 1000 mile trip and halfway home it just shut off. Threw a p0193 code when they checked it on the H&S that said "fuel rail pressure sensor circuit high" the truck has always run perfectly and even after it shut off they were able to get it started again and make it home. Occasionally it would cut out for a moment, and when idling in neutral it would start randomly revving. The rail pressure was also not where it should have been. It was hanging around 25k all the time and would sometimes drop for a moment to 8k or so. Is this a sign of a bad frp sensor or something worse? It never smoked or ran rough after the whole time, it would just cut out and rev up sometimes. Sent from my SM-G930V using Tapatalk [/QUOTE]
