Default 01 2500 Cummins won't start after fuel filter change

Changed fuel filters in our 2007 5.9 cummins and no problem. Did the same change on our 2001 5.9 cummins and now it won't start.

Bump started and listened for fuel pump to engage and pump. Even removed filter cap again and verified that fuel has come to the filter and is OK. It is in our garage on level ground, so pick up should not be an issue.

The water/diesel drain is closed. Does the drain valve also prevent fuel from leaving the filter?? Any other advice is welcome.

Yes it should drain that hole filter housing. You likely got air into the injection pump. One thing I would have done is have another person with you and with the filter cap off turn the key on (no bump start) a good lift pump and you will be swimming in diesel fuel. Also the person in the cab turning the key has to be quick with turning off the key. if that is okay then. bleed the air out of the injectors.
You have a VP 44 injection pump?
If so loosen injector lines at the injectors crank while air/diesel fuel is leaking then SPRAYING tighten injector lines. Wear safety glasses and stay out of the stream of fuel spraying. You will want to be on the passenger side of truck leaning over the engine...
I just got done replacing a VP 44 on a 99 3500 CTD I had to do what i just described to get it to run...

We don't have a reader, so I don't know if there are any trouble codes here.

you might beable to cycle the key 3 times it might tell you depending how late in the year it was made you can try that and if it works it will give trouble codes in the odometer

Did you crack the injector lines to prime them?

The VP44 isn't a self-priming system like the CP3 is, you need to bleed the lines.

You need to loosen (not remove) the nut on the HP fuel line on #1 and #4.

Once you do this, bump the starter and let the pump cycle for 20 seconds. Do this 3 - 4 times to prime the VP44.

Now try to start the truck, but DO NOT tighten the fuel lines yet. Crank it over once or twice.

Once you see a trickle of fuel from #1 and #4, then tighen them back down to 40 ft/lbs and start the truck.

The truck will start rough, but smooth out quickly as all the lines are purged.

Here's what it'll sound like when it fires. This is a truck we did a cam swap on 2 weeks ago.

Coal train is right. I forgot you have a 24v loosen injectors #1 and #4. I was thinking Vp44 with a 12v... Does Dodge even offer that???

Nope, you either had a P7100 or the VE pump in the earlier 12V's.

Sometimes that works, sometimes it doesn't.

The problem is the injectors on the 24V's are jerk syle and if they don't have pressure, they won't pop and you'll never get it started.

The nice thing about cracking #1 and #4 is, 1 - Their easy to get to, and 2 - You can just open the fuse box, pull the cover on the starter relay and bump it over from the engine bay and watch until you get a fuel dribble.
