Won't Start, Please Help...

['007.3]

So here's the problem. About 3 weeks ago I ran out of diesel on the way to the gas station. It's happened before due to inaccuracy of my fuel gauge. I shut it off before it died itself hoping to keep what little fuel was left in the lines. After filling a 3 gallon can and putting in the tank it wouldn't fire up. It tried to several times and also ran for 10 to 15 seconds after using starting fluid. After towing it back to my house and adding another 3 gallons of fuel it still wouldn't run for longer than a few seconds, if at all. I've read threads on here from people having similar problems, and have exhausted almost all of the solutions i've seen. Here's the list:
It's a 2000 F350 with the 7.3, It's got 320k on the clock.
Charged Batteries, tested gpr, glow plugs(although it hasn't been too cold here), checked the hpop level, checked the fuel level in the bowl, fuel pump seems to be pumping fine, starting fluid in the intake. After 2 1/2 weeks of trying to get it started I think the starter is now going out as it is turning the motor over increasingly slower despite fully charged and good batteries. I am taking it off today and getting it tested. Any help will be greatly appreciated.

I'll start off with the basics: Have you replaced your CPS? Have you given it a buzz test to scan for IDM codes? Have you checked your UVCHs? The 1st thing I always ask with a 'no-start' after the CPS has been eliminated is to scan for codes. You could always guess @ the typical no-start areas, but scanning always gives you a better idea.

yea look and see if your tach is moving while cranking

Yeah, the tach moves, I had the cps replaced with the recall summer of last year. I forgot to put that in there. What do I need to check on the UVCH's? I pulled off the OVCH's and tested the gp's from there so I know the connection is good there. And How do I do a buzz test?

You'll need a scan tool with diesel diagnostic capabilities like a Snap-On Solus or MT2500 to do buzz tests. You have the UVCH clips installed?

how about lets start all over , you need to start with the basics first , you are no where near running a buzz test yet , if you have been able to start this truck with ether then i would guess fuel pressure issue , just because the pump seems to be pumping doesnt mean ts pumping enough pressure to run, and just make sure oil is full and in good shape, i think a fuel pressure test is where to start, not a bad idea to get codes pulled as well

What clips do you mean?

['007.3]

And how do I do a fuel pressure test? I haven't seen a schrader valve anywhere so I'm guessing I need a fitting on one of the feeder lines?

They're clips that mount on the inside of that harness. Our trucks don't come from the factory with them & they can cause a no start if they slip off. I'd wouldn't try this yet. Follow SCUFFY's info 1st, as he's an incredible tech that's helped me out with many problems. Wait to see if he responds back for the fuel pressure test, as I'm not exactly sure how to perform one, either, or try to PM him.

Sounds like you got alot of air in the lines.
loosen the fuel rail plugs on the rear of the heads and key it on a few seconds. Let fuel pump out the plugs and tighten them back up and try to start it.
