Complete 6.5TD rebuild with used IP and no fuel to injectors!!Help!

I solved this problem sometime last year but forgot to post the solution. Nothing is more frustrating than reading thru these threads without a definative answer! Anyway, it ended up having air locked in the fuel lines. I found a thread somewhere by Missy Goodwrench that gives the best procedure for bleeding out fresh fuel lines with a new IP. First, pull all the glow plugs. Then prime the system by turning the key to the on position for 45 seconds, you should hear the fuel pump rattling during this. This "prime" forces the fuel through the IP and back to the tank. Next crank for 20 seconds or so, watching the glow plug holes for fuel vapor squiring out. Repeat this entire procedure until all cylinders have a good fuel spray coming out of them. Also allow for stater to cool in between crank sessions. It took about 6 cycles of this until I had fuel coming out of all 8 glow plug holes. Re-installed the glow plugs and it fired right up! Thanks to all who replied, hope this helps someone else with similar no start symptoms.

Hi 👋
I know this is an old dead post but I really hope it finds you still. I’m currently experiencing what you described and this is the only instance I can find of it online. I’m only getting .3 volts dc while cranking.
It’s a new to me rebuilt pump, I’m getting fuel to the pump I can see all the air is bled out of the return port ( I used some fuel rated clear so I can see). I’m getting nothing out of the lines. They are brand new lines from Leroy (thanks dude they look Great!) and I blew air to double check nothing was in them prior to install. Did you try that other pcm you ordered? Did you ever get the correct voltage? I’m so deep into this thing, if I can’t get it running again soon it’s either a big block swap or a manual pump conversion.
 
Jamez, welcome.
We need to make sure exactly what your situation is. Please fill out your signature line with truck details- especially any modifications. Pictures and videos are always helpful.

Do you have clear fuel line going into and out of the ip (injection pump)?
Any bubbles? Can you clearly see fuel flowing through it while cranking?

Was the truck in your possession-running before you swapped the ip?
What about pmd? Was it working and is the same one before you swapped the ip or are you using a new pmd that came on the new ip?

Have you hooked up a fuel pressure gauge at the ip after all the flexible fuel lines? What pressure?

With hard lines disconnected from all 8 injectors- is there any fuel coming out of any of the 8 lines?

What is your cranking rpm?
