- Thank you to everyone for your support and kind words on this project! I never would've thought that it was going to be this cheap and easy of a fix. This truck has been a joy to work on every step of the way. No matter what area of the truck I'm wrenching on; it seems that all it takes is a little general maintenance to get this tuck up and running in tip top shape! Thanks for watching
This also fixed my truck I was in same situation as you until I watched this I had just replaced the filter filled with atf and it was doing same thing so I went in the garage scratching my head watching videos, truck had been sitting for 3-4 hours with atf in it then I watched this and I wondered, so I went out to the truck fired it up and sure enough no more stalling ! Crazy what a little bit of Bruce Jenner fluid can fix🤣
It was my last ditch effort before I was going to try a different injection pump and I was honestly surprised when using transmission fluid fixed it. I’m so glad you were able to get your truck up and running again for cheap. Thanks for watching, I’m glad the video was an asset to you, and good luck with your truck👍
😅😅😅😅😅
Exactly what my brother's old truck is doing. Been pulling my hair out trying to think of what I missed. Going to try this.
It’s definitely worth a shot. Worked great in my truck.👍
🏳️🏳️🏳️🏳️WORKED LOKE A CHARM!!!! LOL. LITERALLY LET IT SOAKED FOR 2 DAUS AND INSTANTLY THE STALLING IS GONE. Did this for my 89. Now!! I known why my 1993 had solid red fuel when I first bought it. The previous owner must already knew about this. Thank you! 🚩🚩🚩🚩
I’m so glad this worked out for you. I guess there’s just a lot of moving parts that can get gummed up by older diesel fuel. Hard to beat a cheap fix like that!
Good job getting it running! I think I've seen the ATF in the fuel trick used by other UA-camrs.
Thanks Magdad! It was a pretty clever trick and I was so surprised that it actually worked🤣. It still needs a ton more work, but getting this engine running was a massive hurdle accomplished.
Good to see it running. I would change filter again after running it a while.That fuel was nasty.
Thanks Jason! Ya it had definitely “varnished” and getting a new filter would probably help it along. Thanks for watching😀👍. Have a great week!
Hey!! 😃 Now that is awesome Cody!! I'm glad the guy gave you some quality advice my friend. Old truck sounds fantastic!
Couldn’t have been more simple of a fix🤣! Looking back at it I should’ve started with the ATF but sure did learn a whole lot about how these engines run. So happy with the truck and there’s a lot more to come. Thanks for the support Zane I truly appreciate it as always.
BTW I’m sure you noticed how bad my audio has been in these past videos. Did you ever have that problem with the GoPro you’ve run? Any ideas how to fix?
I had an old 6.9 IDI that had the same stalling issue. Unfortunately the solution was a new injection pump. It was just plumb worn out. Ran way smoother and stopped stalling once I threw a marine IP in. (Which was the cheapest thing I could find)
Never solved my hard starting issues though. I think the motor was getting low on compression because it was pumping lots of unburnt fuel out the exhaust when cranking. It would require 3 or 4 cycles of the glow plugs to cold start even when it was summer! It would also struggle to go uphill unloaded unless you dropped the manual trans down to 3rd gear. She was definitely tired.
Bought the truck for $1000, put $3000 into it. Sold it for $500. I love IDI's :)
Man that’s too bad! Injection pumps aren’t cheap! Sounds like the truck had all sorts of issues, once these engines loose compression that’s pretty much it. No amount of marvel mystery oils’ gonna solve it🤣. This was my first IDI and I had a ton of fun with the truck. In some ways I still wish I had it
a friend does this on his 96 Cummings. He learned from his uncle that had a powerstroke and what else before that? he was a heavy eqy operator. He filled the fuel filter with kerosene when changing it.
Thanks again...I'm a big fan
awesome video , easy to understand. keep making great videos.. thank you..
Thank you! I’m glad the video was helpful for you.😀👍
awesome vid! Daisy loved it!
Thanks glad you guys liked it😀👍
Buddy; i have the same EXACT issue and you are the only person to go into it and fix it; i now know what i need to do; thanks a million!
I’m so glad this video was able to help you out! Good luck fixing your truck😀👍
@@ydocproductions5593 Friend, i just installed a new filter and ran ATF through it 3 times; on/off/on/off. it comes down off of acceleration now and does not stall; thanks for sharing brother! BTW my truck is similar; 1994 7.3 IDI turbo, but filter and pump are same.
@@jimsworthow531was yours having the issue of rough idle and dying sometimes? What did you have to fix?
@@tuckerlloyd86 yes that exact issue; if i rev up the motor it would die. i learned it is a spool valve in the injector pump. i took off the fuel filter and filled it with trans fluid and would keep revving it many times. i also did the same with sea foam. i let the trans fluid sit in the filter/injector pump and injectors overnight. keep revving it up and down and that spool valve will loosen and work after a while.
I am having a similar stalling problem. Am I mistaken or are you saying that your diesel engine is running on Automatic Transmission fluid, to get it all the way through the injector pump? After you let it set for 24 hours how to you get the ATF out of the injector without in entering the cyclinder? or do you let it go into the cylinder?@@jimsworthow531
Thanks Great Video!
I’m glad you liked it!
Good video, very informative.
Thank you very much! I’m glad you liked it!
Thanks for info sir.
Thanks for watching glad it was helpful👍
🎉celebrate the win!! You journey with the issue was such a challenge but you hung in there. There are good people in this world that will share their knowledge. Great video my friend.
I absolutely have! I couldn’t be happier because I was so close to buying a newer injection pump which would’ve opened up a whole new can of worms. Very thankful to everyone who gave me advice on this truck. Thanks for watching I’ve got a lot more planned😀👍
Man I really appreciate the video I just got this truck for ab 3 grand and have been scared I’m gonna lose on it by putting an ip in it but this video helped me exactly how you explained it man
That’s great to hear Kacey! I’m so glad you were able to figure it out. That’s exactly why I make videos like this is for people like yourself that need help fixing their trucks. Thanks for watching😀👍
Hey man I bought a 1986 f250 4x4 diesel super cab 6.9 idi c6. It had a broken injector high pressure line #2 cylinder. I put new lines on it and am rebuilding a spare ip pump. I have leak at #8 injector and believe the tapping on the top is a bad Injector. So I'm buying a new set and return line kit. I've done this on several 7.3idi and 6.9 idi. I paid 4 grand for my truck. Would not hesitate to work on fuel system. It either will work or not. At worse you have to bleed the injection system of air!
@@jackdaicole7595 Hopefully for 4k your truck was in a little better shape than mine🤣. That sounds like quite a hassle to deal with. The best thing about these old diesel trucks though is that the fuel system is about as simple as it gets. The injection pumps have a lot of moving parts of course but when they’re working properly they last a very long time. Good luck with, it hope it serves you well for many years to come😀👍
@@ydocproductions5593 body in very nice shape no rust some very small dings but no major dents very straight body. Everything works ac ice cold heat will run you out in winter. The tapping turned out to be a bad injector just replaced injectors return line kit high-pressure injector lines and put on my ip pump and a lift pump. Sounds like alot but it sat for a while. Runs incredibly strong no more ticking! Starts in the cold first turn! Did new glow plugs. I take care of my diesels and keep up maintace. I'm building a 7.3 idi 93 factory turbo sleeving down to a 6.9 idi new pistons performace stage 1 cam ip and injectors upgrade turbo kit with intercooler. Water and methanol injection system to lower egts. I'm keeping the serpentine set up vs what's in the truck the old v belt! Lol
The Trans I rebuilt myself did some upgrades and transfer case I went through. I have a shop so I wanted to make sure if there was any issues it is addressed now! I'm dropping the ttb 50 and installing a dana 60 solid axle rough country lift kit on the way 4 inch all new poly bushings body to frame and all suspension. Went with all terrain tires. Will be working on my slide on camper. All aluminum square tubing using a antique camper that's claped out(leaks wood rotted) using its sidings building a well insulated retro for extreme weather -70 cold lol. Plus storage electrical upgrades heaters solar water storage and food. I go to alaska In areas that don't want to have any issues far far away from everything lol
@@jackdaicole7595 That sounds like an incredible truck your building! I’ve always thought those factory turbo’d Idi diesels were pretty neat. Even though I own a 7.3 Powerstroke (that still has that p1211 code.) I’m still a huge fan of the old mechanical diesels.
How many pounds of boost are you going to be able to run in that truck?
Great to see u found the problem and got the truck running right. I'm surprised it even ran with that diesel in it. There was a point in the video when the truck was running it sounds like the bearings in one off your pulleys might be going bad. 4:05 that small bell like sound. I might be wrong just don't sound right.
I’m so happy it was a cheap simple fix because injection pumps aren’t cheap🤣. I looked into it and that’s a good catch. Thank you! I wouldn’t be surprised if it was a pulley or something simple. Thanks for watching😀👍
Just to share my experience, my newly purchased 1994 IDI turbo truck has been giving fuel filter alarms, thinking it was clogged I changed it (second filter since buying the truck 3 weeks ago). I continued to get intermittent indications, so I began running less fuel in my tanks in preparation for possibly having to drop my tanks. The issue got worse, by a lot! Today it died coming down a hill, off throttle, at 2100 rpm. After pulling over I tried to burp the filter head, nothing but air. Disconnected the fuel shutoff, and jumped the starter while burping it. Still no fuel. I got under it and discovered the returns from the fuel tank selection valve were capped. When the tow truck arrived we pulled it to level ground after adding fuel and trying to burp with only minor fuel coming from the filter head. We pulled it to level ground and we’re able to then get good fuel flow. I will be taking it in Monday to check the fuel senders to see if the basket strainers have fallen off, and repairing the returns.
That sounds like quite an ordeal! It’s hard enough to trying to figure that stuff out in your driveway let alone the side of the road. It seems like you got a handle on it and have a pretty good idea on what to fix. Good luck and let me know how it turns out!😀👍
@@ydocproductions5593 I actually (sadistically maybe?) enjoy driving junk to find the bugs. I have never owned a new vehicle.
Love that thumbnail!!!
It’s one of my favorites too🤣!
I got the same stalling problem. Gonna try this NEXT;;;;;
Sounds good. Let me know how it turns out👍.
Bro you the man!!! Worked like magic lol.
Good job on getting it sorted it! The old diesel engines need some kind of lubrication added to the fuel. The new diesel fuel is much dryer (less sulfur) than the old stuff. Looking forward to seeing what else you have in store for the old brick nose!
Thanks Wesley! Who knew a little ATF was all it needed🤣! I’ve heard of guys running motor oil mixed with the diesel to help lubricate the injection system, but I don’t know how well that would work long term. I’ve got plenty to work on this truck, so stay tuned! Have a good week Wesley😀👍
@@ydocproductions5593 some use motor oil, some use ATF, stanadyne is a good choice also. It basically comes down to personal preference. It doesn't have to be added EVERY tank, but it needs to be added based upon how much fuel you go through.
That extra piece on the one injector line is a timing adapter. I am half way through your video, so not sure if you end up doing this. But seems like your metering rod is sticking, so when you let off the throttle the truck dies. To fix it you fill the fuel filter with automatic transmission fluid, or diesel kleen. Start the truck for a minute, shut it off. Let it sit for the night, next day start it up and run it like you stole it. Should lube up the internals of injection pump and break that metering rod loose.
I didn’t know about the timing adapter so thanks for sharing that! You were right on the money! All it took was a little Auto transmission fluid and it loosened everything up in that injection pump. Runs great! Thanks for watching!😀👍
I had use plastic oil drain plug gaskets/crush washer on top of the little plastic caps when I bought the cheap set worked for a long time. But use russ repair for your return line kit and more.
Adding a little more clamping force on top of those caps isn’t a bad idea at all especially since they kind of are the Achilles heel of these engines.
👍
Thank you!👍
WOW that was awesome. I have a 94 7.3 IDI and all of a sudden (after running well for years) starts just fine and idols, but I can drive it a bock or two, and all of a sudden it starts crapping out then stalls. I crank and crank and finally, it comes back to life but then may stall after a block or two. I replaced the lift pump and filter but don't know where to go from here. I did notice then changing the filter though it was only half full. Should it be to the top when removing it? If so what is happening? any suggestions? It's the first diesel I've ever had so am stumped.
I’m glad the video was helpful to you Johnny. It’s hard to pinpoint exactly what could be wrong but the fuel filter should be completely full to the top. Usually if the fuel filter is that low it’s an indicator that the lift pump is too weak and can’t keep up with the trucks fuel demand. However if you’ve already replaced it I would take a serious look into air intrusion. What could be happening is air is leaking into the fuel lines causing the fuel to flow back to the tank instead of getting a steady stream to the lift pump which in turn gives you less fuel into your fuel filter then causing your truck to stall. I don’t know how mechanically inclined you are but below are some things you can replace/test on your truck to pinpoint what could be wrong:
1. Make sure all your injector return lines are not cracked or leaking fuel.
2. Also check the fuel hoses coming off your lift pump for any obvious cracks
3. Another thing that could potentially be wrong is the pickup tube inside the fuel tank itself could be broken and not allowing fuel to run to the lift pump effectively. (However I would only look into it as a last resort).
4. Check to see if the check valve coming off the top of the injection pump is working properly as well as all the solenoids too. (Be sure to put the top cover back on the right way)
5. Another in depth test you can do is to take the hose that feeds fuel from the fuel tank to the lift pump and block it off. Get a fuel hose from the auto parts store, stick one end to the lift pump like normal, and the other end into a canister of fresh diesel fuel. Next take the return line coming off the engine and stick it into a empty bucket to see how much fuel would potentially be put back into the tank.
I hope all of those suggestions made sense and are helpful to you. The good news is that you picked a really simple diesel engine as your first diesel truck. There’s not a whole lot that can go wrong with these engines.
Also below is a diesel parts and service company that has their own UA-cam channel called Diesel Care and Performance located in Tennessee. You can watch their videos as well as call their helpline. Mr. Billy Williams who has been a diesel tech for decades helped me personally with my truck and I highly recommend you give him a call if you need more help. I’ll link their channel down below. Take care.

@@ydocproductions5593 My Friend, I am putting you in my automotive HERO files. Not because I have had a chance to attempt your repair suggestions yet but because you are so kind to take the time to list the possibilities that might be causing my problem. Who else would do that? I can't begin to tell you how much I appreciate it. I bout this truck a couple of years ago but have had relatively little chance to use it because I thought it was worth restoring. The engine ran like a top and it had a new transmission installed just before I bought it. The interior was much better than average for a truck this old. However it needed a lot of attention on the outside, and I didn't realize that under that bed liner was a rotted bed. So I replaced the bed had all of any dents or scrapes repaired new bright work grill bumpers and lights and finally an awesome paint job in that original green/bluish color The truck looks like new, but since all this was done now she has had this running for a while and deciding to stall out problem which has made me unable to depend on driving it anywhere. I have never been any more than a shade tree mechanic at best and have never ever worked on a diesel. It almost stopped me from buying the.. truck because it was like being in a foreign country when you didn't know the language or culture. I know you guys say what a basic engine this is and it probably is but I have had to depend on youtube to learn anything at all since mechanics in my area won't work in it. They want cars that have a plug-in electronic diagnostic readout to solve the problem then slam a new part on and charge 200 dollars just for the diagnostics. They would have to think and try like you do...and did with your truck. This little 7.3 turbo ran like a dream before this. So thank you so much. I sure wish I knew about the fuel tank possibility before I put the new bed back on it. But it is what it is. Thank you again so much. At least you have given me a place to start in a direction that makes sense. Your new biggest fan.
@@johnnyohness Sounds like an incredible truck! Not many of those ford factory turbo diesels out there these days and it sounds like yours is in near mint condition. Thank you for the kind words I’m happy to help. If you have any more questions please don’t hesitate to ask. Also if you’re completely stumped on getting your truck running again; I’d highly recommend giving Billy Williams over at Diesel Care and Performance a call. Thanks for watching once again and take care👍
@@ydocproductions5593 Yes thank you. It is not even close to recognizable from what it used to look like.
Doing one of these is like painting one room of the house, then it makes the next room look bad then the hallway then the kitchen. It's an addiction that keeps you throwing money at a project.
My neighbors were sure glad to see the transformation LOL. If it hadn't run so well when I test-drove it I never would have bought it.
When the bodywork was started on the bed, I said we don't need this plastic liner, so removed it only to find a total disaster of rust from moisture trapped under the liner Just imagine there was already hundreds of work done on the outside. It was so bad I had to replace the bed of the truck. Finding one was like searching for a needle in a hey stack. I was happy to see (once the bed was removed) the frame was almost perfect. No rust at all.
Most long beds were used for work and were damaged like crazy. The only ones were hundreds of miles away but none of those had duel tank openings. I had to buy the best one I could find and then have my body man create the front fule door opening. He did an unbelievable job. Perfection in my estimation. As you can see these projects can bore a hole in your wallet fast. On the other hand, I don't feel so bad when I see the asking prices for a nice one of these trucks.
When you suggested I might have to access the fuel tanks, I thought OMG why didn't I go in there and replace everything when the bed was off? Damn, how stupid of me. I didn't because the truck was running perfectly at the time. So if it leads to that I might have to pull the bed off again? I hope not. But that's a possibility.
@@ydocproductions5593 I haven't started working on it yet because of a pile of loose ends I needed to rap up. But now I can. Thanks so much for the referral. I'm sure I will be contacting them if I get stumped. Thanks again for all your generous advice.
JUST WONDERING...You recommended Stanadyne as the additive you used in your fuel tank. Would you recommend using it on a regular basis? Though I haven't had the opportunity to pursue your great recommendations on my truck. I went down to Auto zone to have some of this additive on hand and found they had the 64 oz bottle on sale for 20.00. That's 50% off. I'm about to go clear the shelf of it if you think it's worth using it on a regular basis. Your thoughts?
That’s a good question. It definitely couldn’t hurt. I’m not an expert when it comes to these types of fuel treatments. In fact this is the only one I’ve used. However I would recommend simply following the instructions on the box. If your truck has been sitting for a while and you have old diesel fuel in the tanks (diesel fuel only last a year or two before it goes bad) putting some fuel treatment in will help. I never asked how many miles your truck has?
That spacer is for the timing light when they set the timing
the diesel fuel we have now will destroy those black o rings the brown ones hold up better
I put fuel rails on mine got rid of them stupid plastic caps
fuel rails are they way to go if you want a daily driver
I love the old 7.3 idi engines I still drive one today
the 7.3 is a fantastic motor the fuel return is very problem for the old trucks they can be fixed
Very interesting! Thank you for sharing that! I agree, the injector return lines are not a strong point when it comes to these engines, but I appreciate how simple they are compared to the truck on the road nowadays.
Hey bud great job. Did you just let the truck burn the trans fluid after it sat?
Thanks Donald! That’s correct, I just ran all the transmission fluid through until it started burning diesel again.
How you do it with trans fluid? I got 7.3 idi in 93 ambulance doing same thing. You have ementy the trans fluid out?
I simply bought a quart of Mercon transmission fluid and fully filled up the fuel filter. I let the truck run for about 5 minutes or so to let the transmission fluid fully work though out the pump. Then I let it sit overnight. The detergents and additives in the transmission fluid loosened up the junk keeping the metering valve from moving freely and has worked fantastic ever since. I never drained the transmission fluid out of the fuel filter, I just left it until the truck started running on diesel again. I also put some Stanadyne fuel additive in the fuel tanks to help as well. Hope that answers your question👍
@@ydocproductions5593 yes that helps a lot. Thank you
Add a couple of quarts of transmission fluid to the fuel tanks and it probably will stop dying
The ebay kit is junk, i used oem barbs and viton o-rings. Worked awesome.
I agree, it’s too bad though that I had to install the kit first before I found out. Viton o-rings I think are the best option when it comes to those return lines
That diesels dealers sticker on the valve cover means it’s got a aftermarket engine n it
I have a problem with my F250 IDI keeps stalling out. I have a 1987 F250 6.9. The engine keep stalling out on me for some reason. Starts up great in the cold and runs. When I drive it down the road out of a sudden it starts to stall out sometimes it gets up and goes again and sometimes it just completely dies. And also I'm noticing it kind of revs little high for a second then goes back down when I'm driving down the road don't know if that's part of the same problem or something different. What do you think it could possibly be. I just put a brand new fuel pump, sending unit, fuel filter and a new german-made shut off solenoid.
Sounds like your on the right track. Definitely sounds fuel related. Those injection pumps are pretty stout, so it being bad probably isn’t the case (did you notice any glittery metallic flake in the injection pump when you replaced the fuel shutoff solenoid?) If you already replaced the fuel pump as well you could be dealing with air intrusion of some sort. As you probably know the fuel return lines are notorious for going bad on these engines.
Lastly the most probable cause it could be is the metering valve inside your injection pump could be “sticking” not allowing the fuel you need under load. Whether it’s the issue or not I’d highly recommend putting some atf and fuel treatment in the fuel filter and run it through your injection pump (a couple times perhaps ). Usually I’m against those “snake oil” treatments, but it worked for me and fixed my truck.
I hope that helps. If you need to talk to someone directly I’d highly recommend talking to Billy Williams over at Diesel Care and Performance located in Tennessee. He’s one of those old school mechanics who knows these IDI diesels like the back of his hand. Good luck with your truck and I hope it’s an easy fix!👍
@@ydocproductions5593 okay thanks I'm thinking of putting some new hydraulic fluid in don't have any ATF on hand. Everything was pretty clean inside.
The previous owner did put brand new tanks so not sure what the old ones look like but everything I took apart so far looks spotless clean inside. The biggest thing is it's not something I can tell it's fixed right away until I'm down the road. The engine runs great starts easy and everything but just all of a sudden the thing just wants to die miles down the road. You don't think it's no sensor or something like oil pressure anything like that?
@@ruffrupp5453 It’s possible it’s a bad sensor but these are such dinosaurs that it’s more than likely a condition where it’s not keeping up with fuel supply (in your case while it’s under a load). It’s a long shot but is it possible that the fuel pickup tube could be faulty/cracked, or old cracked fuel lines running along the frame allowing air intrusion and causing diesel to draining back to the tank?
If you have time to experiment you could run an auxiliary fuel tank with a 5 gallon fuel tank somehow attached to the vehicle. Just run the feed line off the mechanical fuel pump and stick it inside the fuel can and see if your problem persists. It would be a good idea to run the return line in the same can as well to see how well your return system is working too. Simply process of elimination
@@ydocproductions5593 ok thanks. I think I'll try the running hydraulic fluid instead of ATF in the fuel filter first that doesn't work I might try a auxiliary tank. Going to try hydraulic fluid instead of ATF because I don't have any ATF on hand and have brand new hydraulic fluid. I might thin it down a little bit with diesel fuel to water it down a little bit.
I run 2 gallons of Rotella 15/40 and a half gallon of lucas
Nice! I’m sure that engine is gonna last a long time👍
what year is the truck ? And you filled the fuel filter all the way up with atf???
The truck is a 1988, and yes I filled the fuel filter all the way with atf (I believe the fuel filter can hold 17oz total). I let that run through the injection pump for roughly 5 min. That way the additives and detergents can fully move throughout the pump. I let that sit overnight and it worked great for me👍. Hope that answers your question. Good luck
@@ydocproductions5593 ok thanks for responding, unfortunately I tried that it it still seems to be having the same issue
@@jenniferarteaga Sorry to hear that. I would recommend calling “Diesel Care And Performance” located in Tennessee . They’re very knowledgeable on the 7.3IDI engine and would probably be able to pinpoint exactly what’s wrong with your truck.👍
love my '93 idi. 2nd body( live at the beach) that is soo rusty. Biggest problem is the so called " mechanics" that have not done it any favors.
They’re great engines. If you don’t know how to work on them however it can be kinda hard to diagnose.
Run atf in your fuel for awhile then sitch to a good additive going to need it since all diesel today is low sulfur. Not good for injection pumps.
😂30secs later your talking about atf
@@JohnSmith-kz1ll Haha Yup, I was very surprised that the ATF actually fixed it! Ran great after that!
What is your operating temperature?
I’m not exactly sure. There’s no real temperature gauge in these old obs fords. An educated guess would be around 190-200 degrees coolant temp.
Run some diesel kleen aswell
Not a bad idea👍
@@ydocproductions5593 it honestly works great for cleaning tanks
Get a new tank
Ya who knows what was at the bottom of those tanks
