Mr. Murphy struck last night. Changed both fuel filters as I have done previously in the past. Accidently left the drain on the frame filter open a little. Did not prime the new filters the required 6 times. Engine will not start. How do I purge the air out and start the truck?


(2011 6.7 Diesel F-250). It is 15 Degrees F outside at the moment.

 

Should be able to cycle the key on and off a few times to prime the system. How much fuel is in the tank?

I'm moving this to the 6.7L forum, that's a better place for an engine-specific thread like this.

 

I did the same thing once . As Tom says cycle the fuel system 6 to 8 times for the required amount of seconds(seems like it was 10 seconds or so) and it will start.

 

It could be that the fuel cutoff switch may have tripped because of this.


If the purging does not work maybe check it.

 

6 times for 30 seconds is what I've heard. Good luck.

 

At this point, I'd consider 6 times the minimum. When I change mine out, I go by the sound. Or more accurately, the lack of air sound. If you listen, you will hear the frame rail pump run, and eventually shut off, which is roughly 30 seconds. that is 1 cycle. Do that as many times as it takes until you no longer hear air gurgling in the lines.

 

That is the procedure I use as well, and it usually takes more than 6 cycles of the pump to get rid of the gurgling, but I've never had any issue with starting afterward.

 

You can now buy the Motorcraft fuel filters off Wal Mart for $55 plus tax with free shipping

Motorcraft Engine Fuel Filter, MTCFD4615 - Walmart.com

 

I recommend this as well. I typically do more than 8, it just depends on the sounds (gurgling, squealing, squeaking, etc.).


Also, don't crank it too much. The HPFP isn't designed to operate dry.

 

Thanks for info. Is it just the one under the hood they carry, or also the one on the frame?

 

That is the kit with frame and under-hood filters.

 

Thanks. Initially I clicked the link and thought the filter was just an image of what was inside the underhood canister...but on second thought, those are sold sealed. Good price, I guess.

 

Also I've had better luck by lubing the dcfm filter oring with stp and having the tank at least half full of fuel.

You may have also cut your oring or damaged the dfcm canister.

It can be done....I've learned the hard way.

Something to consider.

 

I got my fuel filter set from Rock Auto for about the same price but there is a shipping charge. Motorcraft filters.

 

Just placed an order from dieselfiltersonline for oil and fuel filters Oem with shipping was $73.59
