Hmm I thought 94's were 6.0ltr ?

That would be 04

whoops typo ... meant 04 arent 04's 6.0?

Correct

That's what I thought ... then the OP might get farther with you tube by punching in 6.0 problems rather than 7.3.
In the first post he says he refers to his 7.3 but the 04's are 6.0's and they have been known to have lots of problems that the 7.3's did not. There will be plenty of vids of 6.0's 

In his first post he says that his truck is a 1994, which is why he said the engine is a 7.3L

exactly, no 04 around. its a 1994 and the very first of the powerstroke i think thats why its so hard to find videos on. Only half a year of this exact motor.

Try looking at the injector control pressure sensor also. Check for cracks.

Only a few items were different.
Unhook your IPC sensor on the driver side head, and see if it'll run. It's most likely a oil or sensor issue.

I really dont think it'll fix your issue, but make sure the tin nut is tight on your ipr.

Your injectors are tired at 212k, but they shouldn't "need" replaced. Wouldn't cause these issues if they did either.

When you drain down your high pressure oil system (in this case by letting ot sit), they can be a real bear to get running. The fix after working on the hpop system, is to run it, and hard.

There is something with the early hoop's drain back that's different then on the newer trucks, can't remember exactly what though.

If you think it needs a hpop, I've got one sitting on my shelf from a 95, that should be the same as yours, with. 110k miles on it, I'm sure we could work out a deal on it, it was to good to scrap, but I'm running a later model front cover on the engine, so I don't need it.

That's the cup, you can unplug it and run the truck with it unplugged, if it's oily inside the sensor pigtail it's no good.

This is a total shot in the dark, check the air filter. Since it sat for a while some critters could have made a nest in there and your engine is starved for air.

I actually had this happen one time, 1984 Buick that had a ton of insulation shoved into the air intake and it was full of mouse poo... Fired right up after I found that out!

Ok sorry I'm on page now!

For you mechanics out there what about the wiring harness that runs under the valve cover and fires the injectors? I had mine burn on my 7.3 and it ran like crap and wasn't even firing a cylinder or two. Could it pose other problems like the OP is having?

Yes

[syoungs]

could be this, or could be the main harness where it crosses the driver side valve cover has some chaffing, usually they wont die when ones unplugged or anything though, they just run like crap. if the injectors are starved for good clean oil, and one was unplugged, I could see one starting and dying later.

Check glow plug relay. Or just replace it. They are cheap.

ok i unplugged it and turned it over, the truck did the same thing and just ran for a second. There does looks like some oil inside it though, do you think thats the problem? im going to next try and get the old oil out of the hpop and replace with fresh oil.

One thing I've not seen mentioned yet is the CPS (cam position sensor). Very common problem and I have seen them exhibit the same issue your having. Do you know anyone with a running 7.3 you could swap it out with? I believe the Ford brand (only one I would use) is around $30 on amazon. If you have access to a good scan tool and the truck is equipped with OBD2 diagnosing would be much quicker. Also, even though you have new batteries keep a charger on them until you get the truck running, the 7.3's ecm need to see 150+ rpm before it will fire the injectors.

[Woodchuck]

94 will not be OBD2.

[DRobnsn]

94 will not be OBD2.

I believe your right but I've heard of factory updates on some of the OBS trucks that converted them to OBD2.
