2008 6.4 DIED, TROUBLE CODES

[78f2504x4]

My company has a 08 F350 with the 6.4 PSD, it died and was towed to a dealership. Dealership says failed high pressure injection pump due to water in fuel and warranty won't cover it. DTC codes p2291, p0087, p2269 present. The dealer is trying to sell us a injection pump and install for $9000. Is this system still like the earlier HUEI system where the fuel is supplied through a common rail at 60 to 100 psi and then the injector increases the pressure by oil pressure regulated from the high pressure oil pump. I went to an International Med duty engine coarse in 2000, how much have the systems changed since then.
Thanks John

Its a common rail system now.

Much more technical deal, if they are replacing the injectors and such then it seems in line price wise.


Your pullin the cab off for this procedure.

I may sound stupid here, but if I was paying $9000 to fix a brand new truck, I would be extremely upset.
I'm ignorant about the systems on this vehicle, but isn't their some kind of water in the fuel warning? Just curious, I'm to cheap (broke) to buy anything new myself. :?:

[Bsherry]

Yes there is a water warning system.

You should get a symbol warning on the information center panel and that directs you to open the drain valve under the driver side of the truck to drain out water/fuel until only fuel is draining.

Before I spend $9000 I would have the fuel in the tank analyzed to prove there is water in the tank.

:roll:

I have an 07 Diesel that is supposed to throw an alarm if I have water in the system.

[richter69]

Bout the only way I see warranty to pay for the water damage is if the water in fuel light failed.


Another thing being a company truck they like to fill from the storage tanks they use and they are bad about getting water in them, not saying this was the case.

I have also heard of gasoline being pumped in by mistake and exploding the fuel manifold off the pump, warr no pay there either.

More of a get your insurance involved deal.

All the trucks have the sensors, the 99 and up will log it into the pcm as a trouble code as well.

Is there a high pressure fuel pump on theses new engines?
If the high pressure oil pump failed how is it related to water in the fuel.
If it's a common rail engine like the early ones fuel is feed to a common fuel rail in the head to the injectors and the high pressure oil is feed through another rail to the injectors.
Is there a high pressure fuel pump on these engines, the report from the dealer states "failed high pressure fuel injection pump".

[richter69]

There is a lift pump on the frame HFCM that feeds the high pressure pump with fuel, the HP fuel pump raises the fuel to injection pressure, not like the old school pumps. No oil is involved on these with the injection process.

The HUEI system water in fuel would damage the lift pump, and injectors, on the 08 it will also damage the pump like the earlier units before HUEI.

Also in the dealers report says fuel sample ok.
3 of our trucks fuel at the same station and this one is the only one that had a problem, the driver seems to be up on draining the fuel seperator and such as we're an equipment dealership. I don't trust the Ford dealership.

[richter69]

If the fuel is ok then somthing smells fishy.

[richter69]

I would go up there and ask to see said damage, if nothing take a fuel sample yourself from the HFCM down on the frame.


They could be high in the warranty numbers, still no reason to pawn it off on the customer.



Lunch is over back to the funhouse with all the 6.0's............ :lol:

[78f2504x4]

Thanks for the info Jon.
Are the dealers able to look at all the codes and see when they were set and for how long they were active?

[torino501]

some of the early production 6.4l have wire chaff issues on the high press fuel pump on the fvcv(fuel volume control valve) solinoid under the high press pump cover.should be a warranty deal.ford is beating on us dealers to prove that the pump or the harness is bad.talk about loop holes.the electronic side of these trucks are very difficult to diag.it can be done but its a pain in the ***.

[blueoval_nv]

I had an 06 6.0 that quit running due to water in the fuel and the water in fuel light never came on till we were towing it out of the woods, AND the water in fuel code only came up the second time I scanned it for codes.
I dropped the tank, flushed the system, changed the filters and pulled almost a gallon out of the system, it started a little hard, but its been running fine ever since......should I be looking for issues down the line??

[richter69]

I think I have fixed like half a dozen of the wire chaff deals, the dude that put that sucker on there otta have his *** whipped.


If the 6.0 is running fine dont sweat it.
