Bleeding 7.3 diesel ??

Hi,
I have just changed the fuel filter in my 1995 Ford e350 RV it started up and ran for a few seconds and then stopped, do you have to bleed it to get the air out or will it start with just turning it over and over till the filter is filled with fuel and clears out the air??
Cheers Dave.

Unless there is something else causing the problem. Then you just need to keep cranking.

The only way to bleed the air out of the fuel system is by cranking.

How ever long periods of cranking can cause damage to the starter. So I would not crank for long periods of time.

Crank for 15 seconds, then wait 1 minute then crank for 15 seconds. Do this till it starts.

Like I said unless there is other problems then you just need to bleed the air out.

Before you start cranking bleed the air by pressing the thing that looks like a tire filler crank a little bit then press the thing again.

a 1995 E350 diesel is a powerstroke, so there is no injection lines to crack.

One thing that I do a lot of is fuel filters on older mechanical fuel pump engines (IDI's and early powerstrokes). Re-priming is a pain. what I usually do is get the engine moderately warm before I do the filter swaps. This makes starting easier, since the engine is already warm. I also get a friend to crank the engine while I let it sniff a little gasoline on a rag. The fumes will cause the engine to run on gas fumes, and spin the engine over way faster than the starter can, and will get the system primed in a hurry. Just don't get carried away. You'll have to throttle the engine with the rag. Closer to speed it up, farther away from the intake to throttle it down. Just give it enough to make an idle speed. It will clear the air out of there in a hurry. It also works for getting an engine started after injector replacement.

Cracking Injectors in 1995 7.3 liter F250 Powerstrokes

I just read that there is no cracking injectors in 1995 F350 powerstrokes, but what about F250's? Today is the last stage of installing a newly remanufactured 7.3 liter International engine into my 1995 F250 Powerstroke & I want tips on how to start it successfully for the first time without causing any damage to it. It supposedly was started at the engine factory, but still, I have to somehow bleed the fuel lines and injectors of air, things like that. I just want to know what absolutely must be done before trying to start it for the first time to be sure all bases are covered to protect the new engine.
