Hi guys I have an issue with my 05 f250. With 74k on it , here is my issue it ran fine parked it can out next morning no start, come home latter on it started but ran rough , shut it down no start, next night it starts up ran like ****, but I had a scanner on it no code, driving down rode icp presure ranged from 3 to 4 thousand psi, idle around 600, I shut it off no start again, and well cranking it's only showing 12 psi of icp presure , I'm thinking my hpop is bad, any ideas? Thanks guys
