Need Help for a friend...
Posting for my older neighbor.
1999 Dodge Cummins with about 28,000 miles on it, yea he don't use it much.
Anyhow ,he changed the fuel filter and now it wont start...he stated he filled the filter full of clean fuel when replacing it. The fuel pump can be herd running but...no start, not even like it wants to catch. Just prior to the filter change he said the truck ran great, then bucked real bad, lost power, all dash lights came on but then cleared up and ran good again the next day...then the fuel filter change and no start.
Any suggestions I can offer him?
Thanks.

Yes, that's possible. You can verify the condition by checking the pressure (the best way) or cracking the banjo bolt loose on the filter to injector pump and bump the starter to see if there is any fuel being pumped.

Dead lift pump now that has over time caused his VP-44 to fail (why it won't start now).
Heard it about a hundred times.
Tell him to check for codes using the key trick.

Just a plain ole guy
Sorry folks, but telling someone to spend $400 on a lift pump, and then $2000 on a VP before telling him to bleed the air out of the lines after a filter change is imbarassing to our forum.
Hamner,
Tell him to first make sure the filter canister is full, then open a couple of lines going to an injector, then crank the truck for about 20 seconds. If it dosen't try to start, wait a minute or two, then try cranking again. The issue here is air in the lines. Changing a fuel filter on a running truck isn't going to kill a LP and IP. Keep trying till it runs. It will run bad. Once it fires, shut it back off, close the lines then let it idle till it smooths out.
Then tell him to remember what he did and do it again after then next filter change.

Post right before mine clearly states:
Air bubble that needs bled?
Thanks for the kind words though.

Why take it in that direction...^
Thanks for all the suggestions thus far...UPDATE
My neighbor also mentions that there are 2 pipe plugs on top of the fuel filter housing, so he removes one and installs a piece of clear tubing, cranks the engine and no fuel comes out, but again the pump can be herd running for some 20 seconds!
Now I haven't had a chance to look at his truck yet but, is what he's saying making any sense so far? I'm wondering if maybe there could be a blockage from the tank to the fuel pump
I've had diesels (Fords) since the mid 80's and I know their a ***** when they drop prime but...?

It's shot (the lift pump that is).
It will cycle for about 30 seconds under normal conditions when the starter is "bumped". No issue there.
He needs to get himself a fuel pressure gauge, even if just a makeshift one to see what is going on with the LP. He can get a new pump from a Cummins dealer for about $65.00. That will take that part out of the equation for now. If it has never been changed to his knowledge, than it is due time anyway, no loss there.

The vp can and will (but not always) suck fuel from the tank if the lp fails. Once you open the system it can not prime it's self. It happens all the time people go in for a filter change and get a big honkin bill, and say "what do you mean it was running fine". Sounds like the same song 2nd verse
