sounds like a fuel module sensor is out on it, im like the guy above me hope mine dont start acting up i got 18,600 miles on mine now and had no trouble so far...

 

mines the same way i have 19000 miles and so far i have had the recalls done and radiator replaced and thats it i think if i run into fuel pmp problems im going to install a fass fuelpmp in mine

 

Reading posts on every site, and seeing these trucks on a daily basis at work, I am beginning to notice that a LOT of these problems guys are experiencing are regional. You said your pump was garbage, and another guy had the same problem. Speaking with a technician in Florida, he told me they were having front cover/water pump problems. Up in the Northwest Territories, we saw valves sticking and destroying cylinder heads. Here in Windsor, Ontario we see a LOT of radiators leaking, but not too much else. There is the off vehicle that you get a melted EGR cooler 'cause the rad went low.

I haven't changed any fuel pumps yet - but something to look at, I guess.

At first - I definitely thought that you were experiencing a regen event - the early reflash for the regen had AWFUL driveability characteristics. Keep us posted.

 

Wait - what fuel pump failed, the low pressure pump or the high pressure one?

 

it was the low pressure lift pump. I now have put several thousand miles on the truck since it was replaced and it did fix it. Running great again. Still didn't think I should have to pay a $100 deductible though., but I guess it could have been worse.

 

Glad to hear your truck is running good !!!

 

Help, I am desperate.
I have a 2008 f-350 4x4 dually. It has the 6.4l Powerstroke automatic. 12,500 miles.

I tow a 30 foot horse trailer that weighs 14,000 lbs loaded.
I have towed this trailer 8,000 miles of the total miles on it.
I tow the same load over the same road 12-15 times a year about 600 miles each round trip.
I live in Southern Oregon and there are four passes on the highway I drive that are around 6% grades for 3-5 miles.
Here is the problem, I had the truck in 3 weeks ago because the radiator started leaking and at the same time they performed the PCM reflash recall.

Drove the truck around town and it ran fine (other than the same crappy fuel mileage it has always gotten).
I had a horse show last week and hooked up my trailer and headed up the highway, 4 miles from my home while starting up this 6% grade all of a sudden from 60 mph the engine lost almost all power and slowed to 15 mph. I crawled up the mountain to get to safety and called my partner to bring another truck.
He drove the 2008 in to the dealer (it ran fine after sitting for 45 minutes waiting for the other truck) and dropped it off. When I got back a couple days later they claim they can't find anything wrong and they drove it and it runs awesome.

This never occurred before the PCM Change, Any Ideas? PLEASE HELP.

 

I just went to court with Ford over the exact same thing - the judge did not like it at all that as soon as they flashed it the probs started - never got any better even after 4 more flashes - waiting on the verdict now on the buy-back - it is definitely the PCM - starting to have a lot more probs with these in N TX - like bigangryhillbilly said, seems regional

 

Just joined so I could comment. I got an 08 6.4 in the dealer shop right now. Already had the PCM reflashed about 6 months ago and no problems until now. It died on me the other day going uphill. I had 2000lb in the bed at the time. Wouldn't crank back up. By the time I backed down the hill, got another truck and unloaded so I could call for a tow, I tried one more time and it crancked back up. Drove to the dealer (2 mi) and let them have it. It cranked and ran a few more times, but they finally got it to not crank. They are replacing the fuel pump, and a leaking radiator as well. Bigblockbird, you might have them check the fuel pump. It sounds like you have the same symptoms.

 

I just towed my horse trailer again to see if it would repeat the no power problem.
Got up one hill o.k. and coming back over the mountain just as before all the power went away. Boost dropped to 10lbs. wouldn't rev over 2500 rpms. Nearly got ***-ended by a freight truck pulling the same hill.
Called the service manager and he says. Well we got to duplicate it to find it so now I've got to hook up my flatbed gooseneck and load it to simulate the horse trailer weight.
This is B.S. I am not making this up.
Is there really hope that a judge will make the a$$holes at ford buy this heap back?

Truck towed flawlessly until the pcm re-flash........
