HELP!!! First 6.0!

[MB6.0]

Hey guys new to the forum! Just bought myself a new 2006 Ford F350 ccswb and after a week of running beautifully it has now started to act up! Ran perfect the night before went to go to work the next morning and turning out of my driveway low fuel light came on and almost instantaneously truck started running like crap. No power, just falls on its face, idles choppy and very loud, no smoke at all, no codes at all. Went straight to the fuel station filled truck and ran conditioner through it, no change. Changed fuel filters (dirty,partially collapsed) Followed procedure to bleed air, no change. Let run for an hour with new filters, no change. Day later after sitting all night and all day truck wont start at all cranks fine but wont fire, small puffs of black while cranking. Pulled ICP no change, still no codes, VERY noisy fuel pump and vaccum pump on passenger side is on most of the time. Checked filters again and they are partially collapsed again. Truck has egr delete and a brand new hpop pump. PLEASE HELP! What else can it be?? Fuel pump? injector(s)? hpop?

Sounds like maybe fuel contamination. Is there fuel in the filter on top motor? Did you use motor craft filters? Do you have a monitor? What is your icp reading?

[MB6.0]

yea theres fuel in the top bowl and no bought the only ones they had at my local parts store. If it was contaminated fuel why would it not have gone bad earlier in that tank of fuel? and I dont have that fancy of a scanner so I am unable to get values. But when i unplugged the icp there was no change and still no start.

You would be surprised how many people put reg gas in the tank, I'm not saying that is your case. A lot of guys on this site recommend using the stock motor craft filters, that could be your problem. You need to get a monitor on it and see what you have going on, it could be a bad battery, a bad Ficm, or a high pressure oil leak. Unplugging the icp just eliminates the icp sensor, you still could have a high pressure oil leak.

It may be your filters man. I know it sounds crazy but same thing happened to me a few years ago. Purchased what they had on the shelf and same thing. . . . . . Collapsed! Motorcraft Filters only! Start there, its probably the cheapest route unless you get it on a scanner. Let us know what it turns out to be.

The stock primary filter has a water separating membrane that is very effective, and a bleed port to help remove air from the housing. Did you notice any water during your filter replacement? Did you fuel up recently?

hey guys so i had a good friend bring over his scanner and got some values.

FICM reads at a constant 47+ Volts key on and cranking.

Injection Pressure Reg. - 15 %

Injection Control Pressure Volt - 0.25 %

Injection Control Pressure - 2.8 PSI jumps to closer to 50 psi cranking

Does this help anyone with diagnoses?? Still wont run... Cranks and cranks with barley even a cough....

What else was changed when hpop was replaced. Your icp pressure should be 500psi to crank.

I am pretty sure ICP needs to be 500PSI just to start the truck.

Make sure you give us ipr actual. It looks like you gave us icp actual and ipr desired. It appears you may have a hpop leak or trash in your ipr.
