Fuel Pump.......maybe???
Hi All
Ive got an 2006 F-250 with the V-10 and its been having a few issues.
1st issue- occasional rough idle at cold start. It only lasts for a few seconds then everything returns to normal.
2nd issue- intermittent loss of power and severe bogging at highway speeds (75-80mph). If i go full throttle from a rolling start it accelerates strong all the way up to highway speeds. Its happened twice and I haven't been able to recreate the problem.
I scanned for codes after the first instance and came up with a fuel rail pressure sensor code. I replaced the sensor and the fuel filter and all was well for over a month then yesterday it happened again. This time it bogged until it stalled. Upon restart its running fine now. It did throw a code but I don't have my scan tool with me.
This morning I replaced the fuel filter again and unhooked the battery to reset the computer. So far no issues and it runs fine.
Any ideas?

The first time was with a loaded stock trailer (about 8500 to 9000 lbs) in drive with the tow haul on and yesterday was unloaded in drive. I didnt notice the rpms because I was trying to get the truck safely off the highway both times. Next time I'll make sure to notice.
Thanks for your help

And make sure you monitor the fuel pressure while pulling a load, or hard accleration, or something to put the engine under stress.
Interesting that you have a pressure sensor code.
The 3-valve is a no-return fuel system, isn't it? No fuel regulator?

Today was busier than I thought and I didn't get a chance to check it.
I'm trying to figure out how to test it under load.
It ran fine all day pulling a trailer and the check engine light hasn't came back on.
I did figure this out today. When the check engine light came on it was flashing at first then went to solid. I think a flashing check engine light means detonation and pinging. Just another clue in this puzzle.
Thank again for your help
