Filter should always be pre-filled with new, clean fuel (i.e. NOT what came out of your old filter) prior to installation. Installing it dry leads to the issue you described. Nope, no bleeding procedure necessary if you install it primed, the little bit of air you introduced will be bled out on its own soon as engine is started.

Also critical to check that the inner O-ring from the old filter comes off with it, and that the inner O-ring on the new filter is in its correct position. The o-rings like to stick on the threaded snout of the filter head when you take the old filter off and since it's down low on the motor in this application, you can't see it easily, have to check by feel with a (clean!!!!!!) finger. I have seen them where there will be a whole stack of O-rings stuck on there from old filters, eventually they will get in the way enough that the filter can't screw on all the way, causing the outer O-ring to not get a good seal and letting air get sucked in when engine is running, resulting in starting and driveability issues. Concurrently if the inner O-ring is forgotten during installation, or not positioned correctly, fuel is allowed to bypass the filter, which means rapid death to the injection pump. High quality filters for this application (e.g. Bosch, Meyle etc) have this O-ring retained in position by design to prevent screwups but if you are using a Napa, Fram, etc, it is an easy mistake to make. Make sure you're not making it!

Pumping the pedal will not achieve anything on a diesel, there's no accelerator pump, if you want to bleed fuel system quickly just hold the pedal to the floor. In your case sounds like you got a good slug of air into the fuel system that has not been completely purged. Assuming it now has an air-free fuel supply to the IP, running the engine should get the other cylinders to come back in short order. If that doesn't do it, watch the transparent fuel line between the filter head and the IP inlet with the engine running -- sometimes a flashlight helps. If you see air bubbles traveling in the fuel you have an air ingress issue continuing to cause a problem. Check that the filter is tight, check that that inner O-ring came off with your old filter, if you don't have it, then take filter off again and make sure that the new inner O-ring on your new filter is the only one you are putting on there.

Did you replace the filter initially just as preventive maintenance or to address some kind of running symptom?
