6.4 Fuel issue?
I have a 2008 f250 6.4 and had a code show up the other day p0088 which is fuel rail pressure to high. All of the problem I am having seem to have happened after I installed a spartan tuner. After returning the truck back to stock after being put into limp mode numerous times because of the p0088 code I ran the truck and it ran fine but I went to Drive again and after Start up it just quit running and won't start. It cranks over but will not fire. I checked for Code and now I have a p0003 and a few other codes saying it has a bad ground and issues with the fuel pressure regulator in the HPFP.
Has anyone had this issue or herd of something similar? Could this be something to do with the spartan or a bad HPFP.
