Ran ruff now wont start.

[Dr123d]

I have a 03' F-350 with the 6.0 L. For the last few days the truck at low RPM has been running ruff and seems to have little power til you rap it up to above1.5. Going down the road when it kicks into high gear it was really notisable.

Now today after sitting all night and most of the day it wont start. The guage is at 1/4 tank and checked the top fuel filter res and it is full of fuel. I held down the peddle and it wanted to start but died right away.

I dont know if these 2 things could be related but I could use some suggestions before I call the tow truck.

You should scan the truck first to see if you have any codes. Its a good place to start

I have no scanner guess that will be on my to get list once I figure what its going to cost me to fix it.

could be several things , could be fuel pressure ,even though the housing is full, definitly get codes pulled , waste of time to diag without codes to work with, on a 6.0 could be alot of things , from high pressure oil system, icp sensor, stuck ipr, hung open egr valve , like said before fuel pressure , bad oil, start with the basics , make sure oil is full and in good shape, check fuel pressure , you can loosen the cap on the upper filter just enough so when you turn the key on, fuel will spray out , just a quick check without a gauge on it ,need to get a scanner on it after that , as far as pushing the pedal down while cranking , with it being fly by wire , wont make any difference to pump the pedal

Found a place where I can rent a code reader but to late to get it tonight. I'll get it in the morning and check back with the code readings. I just went out to try it one more time and its starting then shutting down right away just like it did earlier today. if I turn the key offf then on again and wait for the glow light to go off it did it again. started and shut down.

I'll check back tomorrow with the codes I get.

Thanks

Ok time for an update. Put the code reader on it this morning. NO CODES GRRRRRR!

Replaced the fuel filters and drained the water seperation filter. Filters look good.

Pulled the top filter off again after turning it over for a while and there was a lot of preasure and the res had filled up so Im not thinking Im out of fuel.

While turning it over it chuggs (nice tec term ) while trying to start and I get gray smoke form the exaust.

Any Ideas?

Thanks.

do you know what kind of scanner was used ,for it to be a no start , i would find it hard to think there arent any codes of any kind

[Dr123d]

It was a Actron OBD II Super AutoScanner -CP9145 which in the instructions said it would read with engine off and key on.

I already returned it but can go pick it up again if I possibly did the scan wrong.

[vitalidle]

Not familiar with the actron scanners. Does it say it will scan ford powerstokes?

[Dr123d]

Didnt read that far but Im on my way to get it again and rescan.
