The other night I had these two codes. P0088 Fuel/Rail System Pressure too high along with P1000 OBD II monitor testing incomplete.
So, I cleared them and the truck ran fine, no problems nice and smooth. Rail pressure is steady. Well I go and hook up to the 5th wheel and when I start to take off, I get those same two codes again and now the rail pressure is fluctuating a whole lot and it feels like it's missing due to the fuel pressure dropping out. From like 15k down to 8k back up and back down. So. I guess I have to hit up Ebay now and spend 1k+ also some new fuel lines.

Other than that About 40-80 miles a day and she always gets up to normal operating temp before shutting her down. I just wish I had a lift because I'd do a cab off and change the worn body mounts while I was at it. And I want to make sure it's my HPFP before I spend that money.

I had someone tell me it may be a faulty fuel rail pressure sensor?
Looks like I need to search how to test that |

Electronic fuel pressure regulators going bad can cause that on a bosch setup Does the rail have a fuel pressure relief valve? Sometimes those can go and cause rail pressure issues. Bouncing around like that sounds like the pump but maybe you'll luck out |

well well well, look what I have found on another forum.
Just to throw this out there, (show you how much diagnostics matter), I had one throwing the p0088 code. Looked at the tsb, and ordered a pump. Put it on, and a short time later, it was back with the same code. I took a long test drive with the IDS, and the cruise control quit. I talked to the owner and he admitted it would do that. Think about this one, when it would do it, it would also dim the lights (that was important). In the pcm connector, pin 39 is the FRP (fuel rail pressure) pin 16 (next to 39 but above it) is the generator (13.5 volts). They were shorting together internally when hitting a bump, setting FRP too high, and dimming the lights (13.5 volts going to 5). Not I need to inspect that before I go the new HPFP route. My cruise control was not working on those two days, I just assumed it was coincidence. I am hoping anticitizenone chimes in. I have no problem paying or bartering for consultation services.

I had a frps go bad on my mustang once. I spent hundreds on my car and then someone mentioned the frps to me and it fixed it right up.
Try that first, should be pretty cheap. Mine had a vacuum line attached to it. If you unplug it from the sensor it's self and fuel starts dripping out or it smells like fuel that's the problem. |

The FRPS is under the right side valve cover. They go bad at times on those, as does the HPFP. There is also a wire harness that connects to the pump that causes some troubles. It is cheap so replace it when you have the pump out.

Ran the truck again today after clearing the code from the last time I ran the truck.
after 20 miles, and several hard accelerations with Rail Pressure reaching 22-23kpsi and no codes being thrown I am starting to think either an intermittent short or a faulty rail pressure sensor. Now I am not a ford master tech, but I would assume that if it was really the pump or the pressure regulator on the pump it should have acted up on that drive?? Anyhow, I am waiting for my fuel filters to come in and when they do, I'll look at the fuel bowl for metal and contamination and if there isn't any I am going to replace the FRP sensor and go from there. |

Like you said that's definitely a bear of a job to change them out. I bet the issues are being seen more often because age and heat cycles are finally catching up to the trucks. |

So at 173547 miles I'm calling it. I was able to change the fuel filters out just now and they didn't look dirtier than usual, but while looking into the fuel bowl if you really looked hard, I mean hard, you could see what appears to be some tiny silver specks in the fuel. So I am guessing the hpfp is dead Jim.
Interestingly enough I had the same code pop up when towing and when empty, what's weird is when it happens despite clearing the code with the scan tool I can only make like 15psi of boost and my cruise control is out until I turn off the engine and turn it back on. What do you gurus think?
