Ongoing fuel system problem? Maybe...
Here is what I wrote to Jim Rose at the Rosewood Diesel Shop.... Maybe some of you on here can help me out at well...
Hi Jim,
Well first I am writing to you because I found your link on the www.ford-trucks.com forums. I checked out your website and was trying to figure out what the best option would be for me. I picked up a cheap 95 F350 with the 7.3 with 190,000 milesish and by cheap I mean 1700 bucks cheap from a local car sales shop, it was his personal truck and he was having more trouble than he wanted to deal with, with it not knowing much about diesel and not wanting to get hit with a big bill from a shop. When I bought it, it ran ok a little power lacking, hard to start unless plugged in (glow plugs I assumed) and some white smoke while driving and starting. Took the truck on a 4 hour drive with a 35 ft camper/racing trailer for my company as someone totaled our dodge dually that usually pulled it, the truck did fine other than no really being able to get over 60 like the dually usually could, made it home successful and drove around town and to work with it without much problem other than if it sat more than 5 hours it was a pain to start no matter what the temp was. Go on another 4 hour trip with an empty 20 ft box trailer and the truck starts acting up really badly, foot-to-floor it would get up to about 60-61 mph and lose all power, if you let your foot off of full throttle it would stall, if you kept your foot on the floor it would stay running barely until it got to about 35 where it would pickup full power again, very rarely if you feathered the pedal just right you could get it to roll good between 50 and 55 as long as you didn’t move your foot and it was god-awful white smoke until it got to about 55. Get it home successfully (4 hour drive turned into an 8). Until this point I has stopped, changed the throttle position sensor and the pedal position sensor, fuel filter, tried switching tanks and everything simple I could think of that could’ve gone wrong. I assumed I had a leaking injector or something when I bought the truck. Any how got the truck home it sat for a few days because of lack of money to fix it and really not knowing what was wrong, some days you can get the truck to start and other days you cant but it wont drive far out of the drive without dying, thought maybe I had a bad fuel pump but the fuel “canister” where the filter is fills up no problem but the truck acts like it isn’t getting any fuel, attempted a little ether today and cant even get it to fire on that, maybe the regulator or something is plugged up a screen or something? I am at a loss I don’t mind putting a few bucks into it because I know it will last me a while and I don’t plan on buying anything else. Anyhow the truck is just going to be a daily driver with the occasional heavy haul and I was wondering if you could help me out picking out what I should do here. Would stage 1 injectors even be worth putting in this truck?
Sorry for such a long message but I couldn’t think of any other way to explain it to you
Thanks for reading

You should never use ether on the PSD. The glowplugs and ether do not mix well. The glowplug problem is probably your glowplug relay. It is under the plastic cover on top of the engine. It is in front of the fuel filter housing and to the left, if looking towards the rear of the truck.
Try cleaning the little screen that is inside the fuel filter housing. Use a Q-tip that is missing the cotton to do this.
Post back your results after this.

I also did something I know I shouldn't have but i am kind of desperate here, i pulled the filter out, drained the canister and had a friend crank the truck and watched the fuel come into the canister.. it was coming in but in spurts and probably not as much pressure as it should have been?

I believe your problem may be the IDM. I think you can rebuild it. Do a search for it. Or you can buy a new one.

In theory the truck would still at least try to start if it was the IDM because I would only lose half of the injectors right? Could it even be the fuel regulator? I'm not diesel mechanic and I know its late but any little bit of info to point me in the right direction is greatly appreciated.

Sorry to hear the troubles your having ,have you looked at the oil level in your HPOP I assume you have been cranking on it so maybe the HPOP reservoir is low or empty now,hows the oil level in the crank case? when you took the fuel filter out was there goop or crap on the filter? was the fuel in the filter housing clear or dark? when you try to start it is it blowing smoke out the tail pipe?

OK I did a little looking around for how to check that level and found it very easily, maybe I am not such an idiot? Anyhow, I am not at home right now to check it but as soon as I can check it I will give you an update on that.. I really appreciate all of ya'lls help

OK checked the HPOP reservoir and it is pretty close to the top so that seems to be good, oil level of the truck is good as well.. I do get fuel out the shrader valve (the tire valve looking one to the right of the fuel filter) but not much pressure behind it.. cleaned the screen in the housing still no fire..
