bleed all 6 injectors after fuel filter change?

Is it recommended to bleed all 6 injectors after changing the fuel filter?

I failed to cycle the lift pump after changing the filter, the truck started and died within a few seconds.

Bled at vp pump banjo bolt, and bled the injectors I could access when i got it running. If I remember correctly I could reach only 1, 3, 4 5.

Is it possible for air to remain trapped in the injectors I did not bleed?

It is not necessary to bleed all of them, if you are getting fuel to the ones you are cracking, it should start and clear out the others.

Sometimes it may take awhile. Make sure the filter canister is filled with diesel. If cycling the pujmp doesnt help, start by bleeding at the filter housing to the VP44 and at least one (maybe two) injector lines.

You'll get it going :thumbsup

Bleed the filter. You should be able to get it started with just that, but if not you will need to bleed 1, 3, and 4. Open them up good and have someone crank until you get the air out and it tries to start. Tighten the nuts after the air bleeds out, and crank until it starts. Do not crank longer than 30 seconds at a time. Once it starts let it run for a while to get all of the air bled out.
