Check to see if you get any fuel at all from the injector lines, don't need much. Also check that your glow plug system is working properly.

Welcome to the forum.
Yep fuel in doesn't guarantee fuel out of IP.
Look over the diagnostic checklist posted on here for ideas and all the stuff we need to know to give targeted ideas.
Broadly RPM, temperature, fuel are key but details needed including introductions etc.

Be sure there is voltage getting to he shut off solenoid with the key in the run position.

Welcome to The Truck Stop.
According to mechanic, fuel is getting to pump, but not beyond.
I had a WVO system put on around 10 years ago, but have not used it for at least 7. Supply and straining oil made it not worth the effort. Had a toggle switch to go from D2 to wvo.
I have 3 VW diesels, but not quite as familiar with the 6.5. I love the truck, still rust free, but it does not start.
Should I be looking for a new pump?
Thanks for the replies and advice!

I'd try a different PMD. I'd also check that the fuel shut off selenoid is working.

X~2 on the solenoid.
Be sure there is voltage getting to there.

So was this an occasional driver and has been parked for too long (a season) and just doesn't want to start up and run but cranks over fast. Or was this all of a sudden running fine driven regularly but turned into a no start situation in last couple of weeks?
It was used when needed (wood, plowing neighbor’s driveways, moving bulky objects). Had a power steering issue resolved in July, then used it to pick up a washing machine, about a 90 mi round trip. Ran great, no hiccups. Someone upstairs was looking after me, because as I crested the hill on my driveway, it shut off like I turned off the key (only I didn’t). Has not fired up since.
I guess I should have shared that detail.
It cranks, but repeated try’s to start has taken a toll on the batteries. I have had batteries on charger several times before I gave up and sent it to repair. They are not breaking any news quickly other than what’s been posted previously.
Have truck with a mechanic currently, latest update in previous post.
Thanks for replies; look forward to input that will get me running again!

Definitely try a new PMD

Yep, PMD/FSD - pump mounted driver or fuel solenoid driver is a prime suspect. It was a weak link on these trucks. They failed in a number of ways with many doing just that engine stalls or dies like you cut the key switch off then IP won't send any fuel to the injectors. No OBD codes are set. The engine cranks over like normal. Fuel is delivered to IP and it recirculates like IP is working but doesn't inject fuel into cylinders.
There is no good way to test a PMD. It was early tech of electronically controlled injection events so operates in the milli-microsecond range of switching. Most people replace with a known good one (if it turns out not to be PMD/FSD you keep the old one for a roadside fix when the new one fails or use the old one and keep new one for a roadside fix). The best solution was to add a longer harness and mount it between the bumper nostrils or outside of engine compartment heat. They will still sometimes fail but usually, live a longer better more reliable life on a good heatsink mount & location. Check out the forum vendors for FSD's, heat sinks, and harness extensions.

On question 1 the glow time seems a tad short. Also you need to verify what brand glows you have. There are some pretty crappy ones out there.
On question 2 you need to answer ALL of them

Also just because your PMD is less than a year old doesn't automatically give it a free pass
