chgd fuel filter, ran rough, now dead

[mannastev]

Changed the Fuel filter (6.0L 2004) It then ran rough, quickly died and won't restart.

Should I take all the filters off and put them back on and see what happen's? Anyone else have a problem like this?

Thanks in advance

Sounds like the injectors are out of fuel. I am not sure how to prime 6.0's so I will bump this up for you.

upper fuel filter cup has no fuel in it.
Fuel pump seems tobe making the regular noise.
About to take off the lower filter off and put it back on,

For some reason Ford in it's infinate wisdom decided on the 6.0 not to put a bleeder valve on the fuel system. We have taken to leaveing the cap off and turning on the key untill the filter overflows just a little, then tighten down the cap.
Now if you cranked it long enough to run the fuel out of the fuel rails it will still have to roll it over a good bit to purg/prime the fuel rail and the injectors again.

Dont do that. It just needs bled out as stated above.

Fixed. I think the lower cap was on loose and sucked air into the lines. Rookie mistake.

Cranking it a long time seemed to fix it. thanks.

This is a scenario I hear about all too often. The primary filter on these vehicles can be deceiving to the inexperienced, when reinstalling. Due to the fact that it "feels" like it's tight while turning the cap inward. The only way to know for sure, is to visually look at the cap closely, to ensure it has bottomed out. Failing this, the valve inside won't open completely to allow full fuel flow, resulting in a situation where the engine will actually run on the residual fuel that's left, until it is completely depleted.

There is NO NEED to bleed the fuel system on these vehicles, due to the fact that high pressure engine oil is what's used to control fuel pressure at the combustion chamber. If the need arises to check fuel pressure on the low pressure system, there is a 6mm allen plug adjacent to the fuel pressure regulator and return line on the secondary fuel filter housing.

The fuel filter change guide I have from Ford says to turn the key to the on position for 30 seconds, without starting the truck for three times. I did mine like that recently and had no problem starting it after the change.
