So about 3 days ago I made a long 9 hour drive. No problems at all but I did allow my fuel to get a little lower then I normally do. About eighth a tank had 30 miles left on the digital read out. Stopped and filled up at loves where I always get my fuel. And off I went drove it down to 3/4 a tank and made it to my stopping point. Got in to go about 7 miles down the road and come to a stop sign and slowing down the truck died. I thought crap I forgot to turn off the auto start but never done that before. Stopped and stared truck as normal. Made it to my stopping point again. Headed back to the house and doing on average 55mph and truck surges like it wants to die but doesn't. Rpms drop below 500 and it keeps going I get to same stop sign and slowing down again doing maybe 25ish and truck dies again as I have my foot on the break. Put in nut and started it right up and drive on home. Today went about same distance. Only this time I started it with key and was doing down other things while letting it run it just dies start it back up and take off get to where I was going and it surged or hickuped so to say. Again started it once I was getting ready to leave and let it run for about 5 min and it died had the heater on as it was chilly out by the lake. Got in and restarted it and it was blowing cold air and had a diesel smell to it. Wife asked me if truck was going to blow up lol. Backed out of area and put in drive and made it 80' or so and truck died again doing about 10mph. Any one have any ideas or a fix??


Checked so far

Batteries checked and both are good
No mods done to it
New ICP sensor and pigtail
New water pump
New injectors 20k miles ago
Oil changed 1100 miles ago
New filters upper sad lower


2003 Ford F-250 King Ranch 6.0

 

Was the ICP sensor OEM or aftermarket. There have been issues with RF interference with aftermarket sensors and if the truck is shutting off on the same stretch of road that is where I would start.

 

It was OE part and new pigtail. I refuse to put aftermarket parts on my 6.0. I was leaning to it beings something with fuel as I did run it a little lower then normal and it all started after that. I do not have the blue spring upgrade yet was looking at getting that and putting it in to see if it made any kind of difference. I have a 9 hour drive back home and was not wanting to take this thing to the dealer again.

 

Would changing the fuel pressure sensors to the blue spring be a start on this as the part is only about 60 bucks and and then about another hour of my time. I don't know anything about these trucks and for what I have into the truck I really don't want it to go away but my wife is on her last nerve with it and is threatening to sale it.

 

Any one have anything on this any kind of info would be good

 

Wish I could be of more help but just not a lot of info to go on. I think if I were in you shoes, I'd inspect the filters first (no cost, pretty quick job). Pull the water drain plug and flush out the HCFM through that hole with some carb cleaner spray (there's likely to be some junk in there). We change filters at 10k miles assuming decent, clean fuel but one bad tank can trash the filters. Fuel smell in the cab is often either an exhaust leak or a fuel leak. Double check the tightness of the upper and lower fuel filter caps also.

The keyhole shaped gasket on the regulator cover comes with the blue spring kit if you have any wetness in that area it could be an issue. If you are still running the origonal spring in the regulator the blue one will often raise the pressure a few psi, that may be worth a shot.

There are many other possible issues and this is really just a shot in the dark based on your suspicion of fuel issues. If you have a multimeter, checking the FICM volts would be a quick job also. Info on filter change, checking FICM volts and blue spring install is in the tech folder and YouTube videos.
