Hey fellas, I'm new to all this. It's a 94 k 3500 6.5tb had my truck around 6 months. Well it started launching of from take off. Sometimes it would die and start rite back. Now it just turns over fine. I'm not getting any fuel to the injectors iv looked over most of the grounds. New ops. Got a pmd from a buddy he said it's good. Now what many a blocked fuel manager ditch screen?? I'm lost. Thanks

Need to start with the basics. Jumper the LP and verify your getting fuel and pressure all the way to the IP.
Also put a piece of clear tubing on the return from the IP to watch for air bubbles.
You should have a spare pmd with you anyway so buy a new one so you know it's good.
Check to make sure the FSOS is working properly.
Also make sure the glowplugs are working correctly.
If none of these fix it your looking at wiring or electrical issues.

Load test the batteries one at a time?
Make sure all the cables, terminals, connections are good.

Diesels require cranking rpm to start. Has to spin fast enough to generate enough heat for ignition.
I have a charger on it seems like I'm not getting fuel to the injectors

What was that fuel pressure and how was the flow through the clear ip return line?

Is that ACDelco OPS?
What you need to do is energize the Lift Pump using relay jumper or ALDL jumper (so it is not dependent on OPS), make sure there is no air from LP to filter. Then start cranking. If there is no fuel at the injector, the either the PMD is bad or the whole IP is bad.
How is your buddy testing his PMD? If he still have his 6.5l truck and it is running, try to start his truck with that PMD.

Are your glow plugs working? NEVER cycle the glow plugs (Wait To Start) while on a battery charger, especially in "jump start" mode, as the voltage from the charger is higher than battery voltage and WILL burn out your glow plugs almost instantly. No glows will keep it from starting.

But if you don't put it exactly like it is originally, you will get a very fancy paperweight.
How do you know if the OS is shot? If that is a guess, then it is up to you.
I would try another KNOWN WORKING PMD first.
Please don't get the USED TESTED PMD for diagnosis.

Unless you are going testing and not letting us know results, it seems you are missing lots of steps before spending descent money.
