2013 (2012?) FW Expedition 6.7 Cummins.
Changed both fuel filters.
Water separator filled on it’s own.
Prefilled fuel filter as directed.
Cycled ignition switch several times 5-6 times. Wouldn’t start. Tried it again so I quit.

Do I need to bleed it?
If so, how?

Thanks.

Air in lines. Have to bleed fuel from pump forward by opening the fuel lines . search youtube for fuel line bleed should help some

PS: I posted this in Cummins forum and didn’t get much traction.

If you’ll take an air hose with a rag around it and put it in the fuel fill tube have someone crank the engine while you hold the air line with the rag and increase the air pressure the engine will start. Don’t worry you can’t hold enough pressure to hurt the tank.

I had a heck of a time getting mine started after changing filters. Long story but taking off the fuel filter and again filling with fuel worked for me. Had filled it before but seemed to need it again. Mine is Cummins ISB. Good luck.

Thanks for the replies.

This....
I'll add that loosen the fuel line coming out of secondary filter housing and pressure the fuel tank, once fuel flows from line, tighten it up, Crank engine and when it starts hold it half throttle till it runs smoothly.

If you don't have access to air pressure, make sure both filters are full, loosen 3 or 4 injector lines at cylinder head, Crank for 30 or so seconds, let starter cool a bit and keep cranking until you get fuel from all the injector lines. Tighten them up, crank and hold throttle down.

I will try that.

This happened to me the first time I changed filters, same engine as you. In my case I got excellent advice here. I had already done the 'final' filter and successfully restarted. The separator was 'no go'. Per advice here from Skip426 I removed the separator and found that the level was down about 2 inches just as he predicted. I topped it up again, reinstalled and got a restart with no further drama.
I would definitely try this before cracking into fuel lines or gently pressuring the tank, not that those things aren't needed or won't work. To me it's best to avoid breaking into 'something else' if you can get around it by working with what's already been disturbed.
Note, on that first change I was careful to have the fuel tank fairly low for fear of getting a diesel bath. Now, I make a point of having the tank well over half full. I think I was showing about 3/4 on the gauge this year and the fuel drippage was minimal. Plus, it started right up without having to do the 'top up'. Good Luck and I hope that's all you're going to have to do.

Not sure about the newer ISB but on the older ones you have to bump the starter to get the electric lift pump to run longer. Just turning the key on only runs it briefly but going further and getting the starter to run briefly will activate the lift pump for 30 seconds. 3-4 times doing this should get the air out of the system with out opening any lines or putting air on the tank.

The new water separating fuel filter said not to fill it on the side. So, I didn’t. After removal of the old one the fuel was coming out in a small stream from the base.
The regular fuel filter said to fill it, so I did.

dvmweb · 09-19-2019, 05:29 PM

Rechecked filters and they are full.
Still won’t start.

Are you leaving the key at the 'run' position after cranking the engine, and leaving it in this position for a minute or so?

dvmweb · 09-19-2019, 07:46 PM

No.
What will that do?

Pulled regular fuel filter and refilled.
There is fuel at the banjo bolt at the fuel rail.
Still no go.

Dark Sky · 09-19-2019, 08:52 PM

You leave the key on so that the fuel pump runs and helps prime the system. I think my model said it runs for 18 seconds. A few cycles of this should help. I never thought to mention this earlier, wrongly assumed that you knew about this. If it's still a no-start, unfortunately you may have to bleed the injectors or try gently pressuring the fuel tank.
Perseverance will carry the day.
