Ford Powerstroke 7.3L Diesel - Power Loss - Fixed
HTML-код
- Опубликовано: 17 июл 2024
- We bought Meagan a new Ford E-350 with the 7.3L Powerstroke Diesel and it was having problems with loss of power when climbing hills or when you really stepped on it. A "Diesel Shop" had the van for a month and half and they charged Meagan $4000 and it still had the problem. I contacted a family Friend that works at Bear Automotive in Prineville Oregon. He had the van fixed in 2 days. Here are some common things to look for on a Ford Powerstroke 7.3L Diesel that can cause power loss.

Your Primal Outdoors - Camping and Overlanding, I am living the van life in my Ford E350 4x4 Van traveling around the remote public land system in Oregon
Long time 7.3 owner, I currently own 3. Issues for loss of power: cam position sensor (Ford seems to have this fixed with new sensors). Fuel tank pickup 3x (all different vehicles), be sure to eliminate the in-tank filter when you do this, and cut the fuel fill line inside the tank to allow easier filling of the tank (search for harpoon and hutch mod). Fuel Injector control module FICM, probably need a mechanic with a good code reader to diagnose this one. As you mentioned low oil level, or pump failing. EXhaust gas valve. Injector wiring harness. I have put well over 1M miles on 7.3s and still love them, obviously. If I bought another one used I would pull the fuel tank and fix the pickup issue quickly, if it was not already done. It is better to eliminate the filters and the plastic foot, and replace with metal tubing. That plastic foot will eventually crumble and cause you to run out of fuel at ~1\4 tank on gauge and the pieces will clog the filters. Oh and of course bad injectors can cause power loss issues. Keep your oil changed regularly to keep a 7.3 healthy. Keep up the great videos.
Maybe I should finally check my tank filters haha. 396k miles and she’s a bit slow but still kicking.
I ran out of diesel at 11:30pm 1 hour away from home, it showed I had 1/4 left. Now I dont let it go below half tank lol
Ficm is 6.0 only. 7.3s have an idm (injector drive module). They are both injector computers, but they look completely different. The 6.0 ficm is right behind the intake and under the coolant Degas bottle on top of driver side valve cover, and the 7.3 idm is in the drivers side fender behind the fender liner on super duty trucks
You can call it FICM or FIDM, most techs use the term interchangeably. You are correct on the location.
Thank you 😮
I see a video from Jason, I press like. That simple.
Dang , I am sorry that so much money was spent on needless "repairs" at parts changer shops . The shop should refund ALL of the money spent on unneeded parts ! Thumbs UP to you two !
I’m glad to see Meagan’s doing well and recovered from her terrible accident, happy you got the van running well, it should last for many miles.
That $4k with no resolution seems absolutely criminal.
Should be but unfortunately its civil,I’d be a mushroom cloud laying mf’er on that first shop that couldn’t diagnose the problem properly. The proper resolution to the issue would be to find a competent shop, something that is not always easy to do.
Im a retired HD mechanic and also have a 7.3 - I highly suggest a OBD11 scanner forscan - it will diagnose It will save a lot of money on repairs you do not need - it will diagnose a faulty EBP system . Some people unhook the sensor and hook the sensor through a switch , turning it into an exhaust brake - A faulty ebp causes a n exhaust restriction making the engine hard to start when cold . Another poor fuel economy no power is a tubs front of enginre right side theres a sensor tube runs to right exhaust manifold , tube carbons up ,
SO glad you guys have got this resolved. What a needlessly long and frustrating struggle that turned out to be. I’m sure someone else down the road will be grateful you made this video which may save them the headaches you and Meagan have faced with this van. Looking forward to seeing how Meagan’s van build finally comes together.
You're were absolutely right! It helped me today after a couple diesel techs couldn't figure it out.
You got your priorities straight, Jason. Do what you have to do and we'll wait for the time you can get out and do your thing.
Really good information!! Sorry to hear Megan got ripped off so bad from the one shop. I have a 1999 7.3 4x4 Ambulance. Died on me, would not start. Took it to a Diesel Mechanic he replaced a fuse and got it running. As he said, we have not found the problem and can't get it to replicate so we can't charge you ... it's going to happen again. It did 2 weeks later and I took a chance that it was the fuel bowl heater because of the fuse. Replaced it and all is well. Love my mechanic!! Don't find many like him any more!
When you find that one shop that treats you right, you stick with it.
I enjoy all the different content you put out. Excited to see the build out completed on Megan‘s van and what you do to your van.
Glad you got the van running well again and back to living life! Cheers!
I’m glad you posted this. I didn’t know until this video the tank has separate screens in it.
Your videos are great whatever you put out. Happy to see things working out and look forward to the future with both of you and your travels🤙🌲
Glad you got Meagan's van straightened out. Looking forward to her van build. 👍🏻
Very glad that the van is running great! Great video!
I’m so excited for both of you. Meagan, continued prayers for a full recovery both for you and your ride. Jason, you are amazing in so many ways. Great video and I’m sure there are gas tanks dropping across this country as you helped them solve a mystery.
Thankful you resolved the issue & the van build may begin 🚐🛠
7.3 owner here!👍🏽 all been done and this vid was better than a forum!
Thanks for the update, I was not aware there was a filter in the fuel tank.
Great overview!! Thank you for posting this info. This van type is what I'm looking to get, at some point.
Hi guys happy to here the van is up and runing😄😄😄😄😄be safe.
Some of the ford tanks were also known to have an inner coating that would separate and plug screens etc. I ditched the screens and put a racor ahead of the pump, easier to check and change. Glad you found the problem
I appreciate the knowledge. So true of others. Spin lots of time searching for answers to no avail. You gave much knowledge to help. GOD Bless
Wow, Jason you are becoming quite an expert from this project. I am passing some tips to my farmer friends who have deisel tractors.
Meagan, take it easy and don't do too much at once. You look great! The fresh air and sunshine has been working it's magic.
Glad you found a good shop to diagnose it properly and not just fault out the pump saying that it’s the cause. Instead they correctly diagnosed a problem without throwing the part at it.
Great info. I don't have a 7.3 but I'll pass this video along to a couple of buddies that do.
Congratulations on getting it fixed!! On to building a home!!!!
Great information, thanks for sharing
Enjoyed it! Very informative!
Thanks for the vid. RUclips needs more 7.3 van videos!
Glad this is working out for you guys. God Bless.🙂👍
Thanks for the tips .. Been getting some power loss pulling up hill here in the Rockies with our Powerstroke 7.3 F250, I'll check a few things you mentioned.
Awesome video. Thanks for making it 👍
Maintenance is all part of the adventure. No need to worry about delays. It keeps us engrossed in what you're doing.
I love seeing any videos about the 7.3
The lack of resolution on problems in forums is frustrating to me too! I always follow up bc of that. Thanks for your video. I have really enjoyed my 7.3 after 5 years of ownership.
Great video, I was having all of these problems, thank you so much!
Very helpful you guys.
Thank you.
Knowledge is power thank you jason
Thank you SO much for this video. You are very clear/succinct in your delivery and that's very appreciated. Have the exact same issue, and am going to go and try these fixes on my '97 F-450 7.3L diesel (converted ambulance). Will try to remember to get back with updates. I "liked" this and Subscribed. Good work; very impressed.
Update: I had a radiator flush done (coolant looked old and with some residuals). I cannot believe the difference in the power! It's magnificent! Am still going for checking other items. Thought I'd start with the biggest out points. Again, will update further as I go.
Thank you for the info . I have a 2002 F 350 p/u full banks kit exh. brake. Had to put a hydra tuner in love it. All the things I have to do is minor. Great video thanks again.
I feel your frustration on the forum thing. Sometimes the thread just withers away. I get lucky occasionally.
This video fixed my 2002 E-550 today! Thank you so much! Also I live in Salem, OR so I thought that was pretty cool that we're close to eachother.
Great info. Thanks.
HI JASON 👋
JUST DO WHAT YOU BOTH HAVE TO DO SO YOU BOTH CAN RELAX WHEN YOU CAN GET AWAY ! I'M SO GLAD YOU & YOUR FRIENDS FINALLY GOTTEN IT FIGURED OUT . THANK YOU FOR LETTING US KNOW ! VERY HELPFUL ! THE VAN LOOKS NICE CAN'T WAIT UNTIL YOU BOTH START FIGURING HOW YOU WANT TO DO THE LAYOUT FOR THE INSIDE ! BE SAFE ! HAVE FUN ! HOPE YOU BOTH HAVE A GREAT YEAR 👍 GOD BLESS YOU BOTH ALWAYS ON 🙏 YOUR JOURNEYS / TRAVELS ! ENJOYED 🍨 🍨 🍨 🍨 🍨
Well done…thanks for the content…
Glad you were able to get it figured out Jason. Would love to see you get some money back from that criminal shop
Great advice!
Thanks. I love 7.3 powerstroke talk. I gotta 2001 F350. That’s super nice you can get to the back of the engine from the cab. I too deleted that turbo pedestal valve.
Ditto on RUclips channel's that don't follow through. I put a 12valve in my 86g20 and the damn shop took a year of excuses on delays. Glad I didn't pay up front. I finally told them if they want the rest of the money I would need the van.
When I got it plain safety shit was undone, like bolt left loose on my steering. This is a small town and people are admiring the look and sound, so when they ask about who did what. Well let's say that guy will be needing a new career. So now it's much better but I want to be sure it will make a long trip before I start on the inside. I do have all the innards though.
It's a beast. Think Mad Max meets Walking Dead. 😎
Good luck with Megan's build. I'm looking forward to all the video's. 👍👍👍
I add a fuel pressure gauge to every 7.3 I work on. Can give you a very early heads up. Sorry you got screwed around by a clueless shop.
Invest in a regulated return system. The FRx from Riff Raff is your cheapest angle and there's a bunch of others that do the same thing for a lot more money. The #8 injector tends to starve for fuel as its at the end of the line. (Drivers rear). Adding this to your fuel system will make your injectors a lot happier and noticeably quieter. You may have even noticed less clatter after you got the fuel pickup modified. The factory pickup tends to suck air back into the system when it's worn out.
And with that Hydra I hope some gauges were added? EGT, Boost and Trans temp are all mandatory with a tuned 7.3.
One more... get an OBD dongle and the Torque app or ForScan (works best on a lap top). Being able to talk to the computer can save SO much headache. Regular scanners can't read the 7.3. Also gives you the option for more monitoring of crucial systems.
Beauty rig! Glad you got it sorted.
All these problems, happens to me with a motorcycle, I started to fix them, and then after many months an try and error, I spent so much money I could buy a new one. It seems to me, you're having the same experience. Good luck, let's hope there will not be any more expenses. Stay safe!
My 7.3l is still at the dealership year and a half and still waiting. Damn that loaner truck sure does drive nice. Glad you had someone that could fix it in a timely manner. 😂😂
Great to have it fixed, but it sucks that the shop took you for a ride!
I have India version of sprinter van.... It's old version we are 15years behind ..
This video is helpful... 👍
I've always been a firm believer in Power Service diesel Cetaine boost and fuel system cleaner, plus winter anti-gel treatment. Here in Colorado it's a must come winter or you'll be 'one of those guys' in the morning on a below freezing day sitting on the site of the road. Not all stations add winterizer especially in early/late hard freezes.
BTW- nice van, I'm sure it will become a nice home.
Im amazed a diesel shop charged you for a non fix. Good on your family friend. 🇨🇦
Thanks for all of the info. Us 7.3 van people need this. Mine is an 03 7.3 4x4 that I built myself using the ujor kit. I deleted the ebpv on mine too. The t-stat fitting on mine started leaking and I replaced it with the Sinister Diesel one along with the 203 degree t-stat.
Yeah, the stock T-stat fitting is kind of crappy, I did you have to get a different hose for the Sinister fitting?
Jason
I used a 12 gallon Marine Tank to isolate possible tank and pick up issues. I worked on the 444E (7.3) version for several years while working in a International truck shop. Isolating fuel source is an inexpensive way to real time check hard start/no start and power issues on a International 7.3 E engine, or DT466E. Cummins, Detroit any suspected of fuel delivery problems. I have Seen the lift pump seize in the Valley and break the camshaft in half. The Brand of oil and Level is very important to prevent foaming.
Good to hear you resolved the issue. (If She is happy, than so am I)
I have a 2003 E350 extended with the 7.3. I'm in Salem, Or. I would love to get the 4x4 conversion. Great info, thank-you.
Love the 7.3 van stuff. They are very rare, used to have one. Let it go when i found a duramax van.
Super well described
With your walk through
Wish every one who watches you video would learn on how to properly identify it's symptoms and causes and it's true meanings on parts rather then hand out like slangs and hangs great perspective guys thanks for your awesome English really appreciate you...
Excellent video 😎. I'm subribed
Don't apologize about different content. It's all good. Thanks.
Those fords are also known for fuel tank delamination. Whatever coating they used inside the tank would come off and clog those screens. I have owned 3 7.3 trucks. Excellent motors with a few quirks. Carry an extra cam position sensor in the glove box!
GM's had the same issue.
So glad u got it fix also u can get fuel injector cleaner put in gas tank help clean the gas tank also carburator cleaner put in gas tank maybe that will help clean the engine and gas tank
Running a fuel additive like
Hotshot's secret, everyday treatment
Helps alot.
Always add some diesel fuel conditioner at fill up.
Yes. 10 years of owning a 2000 VW Jetta TDI, almost 200K miles and I used the white bottle Power Service Diesel Fuel Supplement for enhanced lubricity, just a few ounces as recommended for my size fuel tank. This was especially important because during my ownership of that car, the sulfur volume in diesel fuel was very substantially reduced here in Illinois by either state or national mandate and as we know, sulfur contributes to lubricity.
It's awesome Jason. I'm not even a ford guy but love the 7.3 amazing international engine. I love your van but Megan's sounds better lol
you always work your way from the tank to the engine, Diesels especially.
@Broken Ankle Sports 🏀 eeeya ooook
Very good explication i have 05 ford econoline e350 hevy duty diesel 6.0 i have tha seme problems
While I'm normally a Dodge fan, I just bought a 92 F350 with a 7.3 in. Drove it home 300 miles and around 100 once I got home. Then started losing power and it barely runs 50mph. So, I guess I get to run through these checks. Thanks for the info!
Awesome!
I had the same issue and deleted the factory in tank screens and fuel pickup lines. I also added a see through fuel filter on the frame rail before the fuel pump, just to protect the fuel pump.
In my navy career I’ve only seen bio growth in our jp-5 helicopter fuel once. But the helicopter would get a “phase inspection “ or serviced very regularly. Honestly I thought an anti-algae additive was already in diesel fuel from the pump these days. But I did use and injection cleaner regularly in my VW TDI and usually got 3-5 more mpg on that fill up in that car and it was at 300k miles. However when temps got into the 20’s i used anti gel in the fuel no matter what the diesel pumps said . Got stranded until I could get heat under the car once. What a pain!
One other thing that also happens to the under valve cover injector harness on high mileage 7.3's is the wire insulation can become brittle and literally fall apart causing a short. I had this happen to both sides between 240 and 250,000 miles on my van. Both times I had to replace while on the road and that was not fun. The right bank went on me in your neck of the woods in La Pine. An air ratchet comes in big handy when working on a 7.3 van cause there is barely room to turn a ratchet on some of the valve cover bolts. Unfortunately I don't have onboard air... A new harness can be had from most auto parts stores as a package with a new valve cover gasket and there are clips on the aftermarket product that hold the wires in place on these to prevent the problem you mentioned from happening.
Great video. I only wished you gave part #'s for the exhaust valve delete items. Thanks again!
Same thing happened to my 7.3 van. There wasn't any algae, but those intank filters were caked with sand and dirt from 20 years of fill ups.
A great way to DIAGNOSE this is fit a fuel pressure guage and drive it. My fuel pressure was dropping from 60psi at idle down to 5-10psi under boost, obviously the engine would nearly die out and van was undriveable. My 2002 was steel tank, no liner to deteriorate, think that's an issue on '99 up SD truck tanks
Yikes... $4000 with no fix. That would really annoy me to no end.
Interesting vid, good info.
Have done many up grades to my 7.3, injectors, turbo, intercooler (97), HPOP, up pipes, exhaust, chip. Best up grade was an after market fuel system, 7.3 is picky about its fuel pressure, the stock fuel regulator is before the heads so when the rpms go up, a tired fuel pump dosen't keep the fuel pressure happy at higher rpms. An after market fuel system is a regulated return after the heads, meaning it keeps the fuel pressure the injectors use at the pressure you set it at all the time, regardless of rpms. With the frame mounted pump, spin on filters and spin on water separator, change out is much easier. More so on a van body, you don't even lift the hood. Bleeding the fuel system is also much easier, just turn the key to run. Prob would not have done all the other upgrades if I had changed the fuel system first and yes I did try a stock fuel pump first.
Mine was losing power after it got up to around 1500 rpm . After a lot of smoke from the exhaust and spitting and sputtering for about three minutes it would catch up and run like a champ. It was the easy one . Low oil . Needed 3 quarts . I actually went ahead and changed the oil . Filled it to the correct level . Problem fixed.
Thank you for the video. How did you delete the fuel screens ? Cheers
Good content! I’m starting to work on upgrades for my 1995 E350 Ambulance and I’m wondering what down pipe you’re using there. All I can find is 3” and that looks like a 4” pipe. Hopefully someday it’ll get 4x4 swapped.
Might want to keep an extra cam-position-sensor in the glove box for the 7.3. Everything else, just pour some Pendleton on it. Seems to work for a lot of other things. Excellent engine for longevity. Take care and God Bless.
If you repair the wire harness that goes over the driver side valve cover, you will never waste time on a cam position sensor again. Unplug it, fold it back, and tape up the spot that is worn through and arcing on the valve cover.
If your getting algae in your tank you also have a moisture issue. You should consider a water separator as a pre-filter.
Do you have the pedestal and exhaust port part numbers needed?
I think I'm having the same problem w/ mine.
Thank you and great content 👍
You can check each valve cover gasket by exhaust manifold temperature
You mentioned the PHP Hydra chip. Did you have to get custom tunes for the van? Or will the generic tunes from PHP work on our vans?
Where did you send it to get the 4x4 conversion? I just bought a van just like yours but an 01 and would really like to do that! Thanks for your time
Couple things...
I'm a very new owner of a 1999 F350 7.3L Powerstroke, so take this for the free advice it is...😜👍
The wires that you referred to that run under the valve covers are for the glow plugs, but do fail for the those reasons. Becareful on install, it doesn't take much of a pinch & you'll be replacing them. Common issues with the injectors are the O'rings, they seem to fail before the injectors (recommend motor craft) The exhaust valve delete, THANKS I've not heard of this before however like the idea...fuel screens, if you plan on keeping them BE VERY CAREFUL with the O'rings I'm told there are no replacements out there.... I've seen some folks do a fuel bowl-filter delete. I'm not a fan, however the fuel screen delete, replaced by an inline filter like a Napa gold, something that could be replaced with every or every other oil change would be preferable. There is simply to much junk in today's fuel. Another upgrade I'd recommend for your van or any 7.3 is a cold air intake. Opening up the air is a big improvement.
Thx for the video...👍👍

Glad Meagan's van is now working. Way too many commercials though.
Yay!
jason, a buddy of mine suggested to add 'standyne' injector cleaner into my fuel tank every other tank full for my 2003 6.6 duramax...seems to run really good
Never add that crap it will blow the motor
I know that frustration 😤😤😤
I live in northern Arizona where temps can get below zero at night. Was wondering if the on delete wud affect the start up w my cold winter temps. P.s my elevation is 7000 feet
Alright Meagan!!! ✌☺🇵🇷
Easy on the road fix. Unhook fuel line before prime pump and take filter off under hood. Use air machine blow filter out and line to the tank out. Works temporarily til able to drop tank out to take off sock and change filter
Hydra is good. Nice to have a high idle program now that the EBPV is gone and grab a bit of power and economy while your at it. Having firmer shifts is nice to.
Google ICP and IPR and show her where they are as well as a cam sensor. These will all leave her stranded, but can be changed on trail.
The ICP craps out, you can swap it with a wrench and it's easy access on the top drivers side of the head. The other thing that happens is the oring fails and dumps all the oil into the valley on the motor. When that happens, loss of oil pressure will shut down the motor and leave her stranded.
She should also buy a Bluetooth OBD2 dongle. I use a BAFX from Amazon. It's 20 bux and along with downloading Car Guage Pro, it will allow her to perform things like, "buzz" tests on the motor to check injectors/ glow plug connections, balance test, etc etc. It's great for diagnosis.
Consider a sump as well for the van. On all my trucks the pickup tube breaks. You'll have fuel but you can't reach it. It's a, "puck" pretty much that mounts to the bottom of the tank and pulls diesel off the bottom.
Last but not least.... the IPR needs a very deep socket. Whats cheap, and works, is harbor freight shower valve socket set. It requires (if i remember right) a deep, but thin wall socket. The wrench set isn't a socket so to speak, but it will let you get the job done while the fuel bowl assembly is still installed.
There's other things, but those mostly will leave you in the woods.
Good luck. I've had my 7.3s all apart. Easy, cheap fixes of you stay ahead of them. Carry extra ICP, IPR and Cam sensor for good luck!!
I’ve been dealing with a powerloss issue for about 8 months now, my issue turned out to be the valve cover wiring harness failed creating a lot of resistance to injector number one and eventually taking the whole bank out till it cooled back down again
Any and all diesel big or small always start at beginning , I have been around trucks all my life , a friend of ours has a 2019 sprinter , he went back and forth with dealer many times , no power sputtering at altitude and so on , I told him to pull the tank he told me in many words i was crazy because its a new van , we pulled it and it was a peace of tape from the manufacture about 2 inches long flouting around
All diesels are prone to contaminated fuel systems and bad fuel lines
Which exhaust did you go with? Muffler? How much louder is it?
