Replacing the Fuel Injectors in a 7.3 Powerstroke Diesel | Ford F-250

[@tracynichols6535]

I have been looking for this video for years. I am second owner, at 45000, and I now have 481000 miles on my truck. The few things that I have replaced in the truck would be, Water Pump, Alternator, Power Steering Pump and hose and Hydro-boost. It is a 6 speed, and is everything I could ask for. No real miss in the engine, just mileage and thinking about doing a full under cover rebuild. What would be the opinion should I open it, or leave it alone?

[@ProjectTimeGarage]

Start here: amzn.to/3AjMu33 This is the Archoil fuel additive and Oil additive. I absolutely swear by this stuff. Stiction is the issue with 7.3 and 6.0 injectors and the Archoil additive makes MAJOR improvements. I run a bottle in every oil change and a measured amount in my fuel at each fillup.

[@jacksmith730]

If it works don't fix it.

[@ProjectTimeGarage]

@@jacksmith730 lol, in my world if it ain't broke, then poke at it and fiddle with it until it breaks. Then fix it.

Hands down the best injector video out there. I was able to tackle a job i was scared to do alone, and save some money! Thanks!

[@ProjectTimeGarage]

Thanks man! Glad it helped out!

[@swink49]

My neighbor is a diesel mechanic he said it’s very crucial to clean the bore from any oil before installing. He said it could cause it not to seat and leak compression into the fuel

[@ProjectTimeGarage]

Yes, it's really important.

Thanks for your videos and responses to these comments. Update that might help some folks. Readers digest version! Truck smokes plumes, Powerstroke specialist says it failed compression test. Bad engine needs replaced $12,000. I seen your video and bought scanner. FORScan says # problem. Pulled injector and had it tested. It was over fueling at idle. Replaced one injector and truck no longer smokes.!!!! So your video and my gut instinct saved me 12 grand. So don’t openly trust mechanic shops. Not all are dishonest but not all are either. Good luck out there people!

Good catch - saved some $$$!

Love the details, was determined I needed a new set but turned out to be a bad internal relay in my fuse panel, I did a quick fix with a bypass and it runs great, I still plan on upgrading them with the truck being over 300k miles. I definitely didn’t think a 7.3 could suck fuel off suction to the point it’ll barely idle but it sure did, love the videos and hope future issues can be easily fixed

Glad to help!

[@jamesschultz30]

Im just about to wrap mine up. A couple of things that made my life easier. I used some much longer bolts with a nut and washer to replace the rear valve cover bolts. This way i didn't have to be a contortionist to tighten them back down. I also put the wiring harness on first, without the gasket. Then attached the gasket to the harness. This made it much easier especially on the driver's side.

[@ProjectTimeGarage]

Good info, thanks!

[@williamgreer7337]

Just curious, recently bought a 01 7.3, 265k miles on it. I’m having a slight few motor issues with it, she cranks and runs and drives. But she’ll throw “service engine soon” on the dash after driving 5 mins down the road. I’ve kinda ran my own little diagnostics test on it as I can. Been meaning to buy a scanner to run a buzz test. Talked to few family mechanics about everything. Just decided to go ahead and replace all injectors and valve cover gaskets, due to no service log of last replacement. What exactly do you mean at 24:08 “evacuating the cylinder” I’m just curious. An ive also read on the comments about “cleaning the bores out”. If you got a little time to explain, would be much appreciated. Very clean and nice video sir! Thank you!

[@ProjectTimeGarage]

The service engine light on these engines are really basic. Unlike modern engines, most of the time the light is innocuous. Every one of these I've ever seen will throw a check engine light. Mine does the same as yours, throws a light after driving for a couple of minutes. In my case it's the Exhaust Back Pressure Valve that is no longer there. It'll also throw a code that "the boost is higher than expected" if I get a heavy foot since it's running a larger tune. Long story short, It most likely means very little. The evacuation of cylinders refers to clearing out all the spilled oil that drains into the cylinders when you remove an injector. Basically, when an injector is removed, there is a fair amount of oil that will pour down into the cylinder and sit on top of the piston. If not removed, there is sufficient oil to cause major damage at startup.

Thank you!

[@bradvidrine8283]

Sir, This is by far one of the most informative video's I have seen on KZbin. Thanks for great content. I have a 7.3 that has an intermittent miss and suspect an injector issue. So the question is whether the Bluetooth device and app would help diagnose which injector is suspect?

[@ProjectTimeGarage]

Brad, thanks so much for the nice comment! I'm sincerely glad my content was useful. Regarding the Bluetooth, yes it will absolutely help you track down the suspect injector. The software is called ForScan Lite, it's free and available on the Google Play store. I have a link in the video description to the bluetooth OBDII connector I use. Other than that, you just need an Android device (phone, tablet, etc.)

[@ProjectTimeGarage]

No, it's not necessary to remove the fuse

Very descriptive review on multiple possible issues. Great detail and smooth explanation throughout the whole install. Great job 👏

[@ProjectTimeGarage]

Thank you sir. Much appreciated.

[@Dallmke]

Great video! One addition. If replacing cups and injectors, put bucket at the tailpipe to collect the supersonic coolant and fuel mixture that will prove you have compression. Alternate plan is to have a bag of cat litter ready.

[@ProjectTimeGarage]

LOL, cat litter for the win!

[@213madd9]

My question is what's the order of cylenders the buzz test does? Like the first one was no good in your video which injector was that under the valve cover

[@ProjectTimeGarage]

It buzzes in numerical order 12345678 - Number 1 is on the front passenger side, 2 is the next one back on the passenger side and so on - number 5 is front driver side

[@DomMangano-r2b]

Should you pull all glow plugs to evacuate cylinders even when only doing one injector?

[@ProjectTimeGarage]

No, it's only necessary to evacuate the cylinders that had the injectors replaced.

I changed the injectors in a 2002 F250 7.3 auto 4WD and now while idling for about 15-20 minutes it will stall out. Pop while idling is pushing about 470-500 psi. when it begins to do stall out. Any insight? Where to start?

[@ProjectTimeGarage]

If the HPOP is maintaining 500ish at idle, then that's ok. It must be losing fuel pressure. That's the next thing to check I would think.

[@MikeConner.akaRadio]

How long did it take cranking it over before your truck finnaly started? Im having that issue now big time

[@ProjectTimeGarage]

It takes a bit of time. Say a minute or so total crank time. Best if you can get a scantool that will read the high pressure oil system. It needs to be around 700psi before the injectors will work.

[@justice101497]

OK real talk, what are those Allen key plugs actually called. My buddy dropped one down the pushrod of my 7.3 and I haven't been able to find a replacement anywhere. I looked up HPOR plug and the results do not match the bolt have have for the other side.

[@ProjectTimeGarage]

I've always called them oil rail drain plugs.

[@justice101497]

@ProjectTimeGarage damn, I can not find the right size bolt for it. I've looked everywhere and only found 1/8 inch bolts. Well thanks for the reply though partner.

[@ProjectTimeGarage]

@@justice101497 Man, I mis-spoke there. They are 8mm bolts, one above the injector, and one below. Only remove the one below. The one on top just serves as a anchor point to hook the injector hold down on to.

What app was running on the tablet? I’d like to see what my HPOP is putting out. This video is SUPER helpful. I know my truck is lacking for power, I do a lot of heavy towing with my 7.3 and want to make sure it’s running tip top

[@ProjectTimeGarage]

The app is called Torque Pro. I have an entire video covering the basic setup of it on the diesel trucks.

[@richardk7327]

Hi. While pulling one injector I got a lot of oil pouring out. I did pull the drain plugs first. Is the best way to evacuate all the oil from that cylinder by pulling glow plug and cranking? Or should I do something else also? I haven’t cranked it at all yet. Thanks for your help.

[@ProjectTimeGarage]

That's exactly how I evacuate the cylinders on all of them I've done. Replace all injectors, leave all the glow plugs out and turn the engine over.

[@richardk7327]

Thanks, I only changed one injector. Want to make sure that’s the issue before replacing all. I wasn’t sure if I could only remove the one glow plug to evacuate cylinder. Seems like I could but I never done this before. Thanks for responding I appreciate your channel sir!

That is all that has ever been done. The thing is a train. But as I'm nearing 600,000 miles I'm getting real nervous about all the luck I've had running out. Trying to learn as much as I can, but just wish I was more mechanically inclined.

[@big_timmy1036]

Everytime I’ve done injectors on a 7.3 it ends up hydro locking. I’ve never removed the oil plugs. Could that be the reason? I’ve always noticed fuel draining when I pull the injectors. Thanks

[@ProjectTimeGarage]

I'm sure it is the reason. I've never had a hydro lock doing it this way.

[@ShaneSapp]

I had the injector out and turned over the crank with the harmonic balanced bolt to spit oil out of the injector hole, I had the glow plug left in. Is this a sufficient enough evac or do I need to take out the glow plug. Just changing injector 8, scanner said 8 and the oring was cracked

[@ProjectTimeGarage]

I'd say you're fine.

[@karlfelber]

With this app can you do any converter lock up

[@ProjectTimeGarage]

I don't think so.

[@medina2016am]

Do i need to wait for the drain plugs to get all the oil out before taking out the injectors?

[@ProjectTimeGarage]

They drain pretty fast. Give it a couple of minutes.

Do all stock 7.3 trucks have that device to attach the FORscan device? Or does the truck have to be tuned to use that FORscan device?

No, the stock trucks will do it straight from the factory. FYI, I have a video coming out on Friday March 3rd that goes over everything OBD2 and Powerstroke related for the average guy.

Hi just wondering if a guy shouldn't change injector cups too since he is already in three? Thanks, great video.

[@ProjectTimeGarage]

I actually get that question a lot. My thinking is that they typically don't fail unless they're overheated, or something else gives up. I have a video series on changing them out, just never done it unless they start leaking.

Is there an passenger side video available also I have a leak where I'm running thru 2 and a half gallons in two days only leaks while running

[@ProjectTimeGarage]

I think I have a video on a different truck that shows the passenger's side. Basically the exact same procedure. Remove the battery, charge air pipe, MAP sensor bracket, and optionally unbolt the A/C Compressor and lay it over for more room. No need to discharge the A/C system.

[@cccEngineer]

Pulling the drain plugs from the under the valve cover isn't necessary because if you crank it over it'll just push it all out the glow plug hole anyway. Just seems redundant unless I'm missing something.

[@ProjectTimeGarage]

It's really about the amount of oil that drops into the cylinder without removing the plugs.

If the injectors are in the bore, it really doesn't matter much. If you're following what I did, the injector harness isn't hooked up yet, so even if there were fuel rail pressure, the injectors can't fire.

are all the injectors the same or is there one specific that goes in #8. if so whats the difference?

[@ProjectTimeGarage]

For early 99, they are all the same. Some customers were complaining of a "cackle" at idle. Ford found that the #8 injector was making this sound since it's the last injector in high pressure oil rail. There was an updated injector issued to quiet this noise.

[@richs65treebucketservice24]

I see how to drain the oil out of the rail prior to injector removal , But what about the Fuel ....? Just let it drain down on top of the piston ....? And at the end of your video going down the road ..What is that big blue critter with the gauges and pressures it's tellin ya .........? Will the BAFX also give ICP pressure ......?

[@ProjectTimeGarage]

Yep, don't worry about the fuel drain, there's not enough of it to really matter **IMPORTANT** make sure to roll the engine over with the glow plugs out to evacuate whatever may have drained into the cylinders before you button it all back up - It's just cheap insurance. The gauges were from a plain old android-powered tablet running a piece of software called Torque Pro (from the Google Play Store). It uses Bluetooth to connect to the BAFX OBDII Reader. Also, grab a copy of ForSCAN from the Google Play store too, it's Ford specific and gives you some bi-directional control over the ECU. Yes, you can see ICP/IPR and a lot of other stuff with the BAFX reader and either TorquePro, or ForSCAN.

I use the Archoil additave for my oil and fuel in all my trucks. I do recommend the injectors from Full Force Diesel. I've used a whole bunch of them.

[@ttvitz0neshotv237]

Do you have anything on knowing if injector cup is broken?

[@ProjectTimeGarage]

I have a video on replacing cups. If one is cracked, you will have diesel fuel in your coolant.

[@ttvitz0neshotv237]

@@ProjectTimeGarage ok thanks man. I don’t have that issue. So I’m gonna go ahead an say my cups are okay.?? Have #3 and #8 throwing contribution/balance fault codes. Unfortunately gonna have to do all 8. Honestly was scared to do it myself. Until I watched your video, I Fersure can do this on my own with your video playing on the garage tv.!! Really appreciate it!

[@ProjectTimeGarage]

@@ttvitz0neshotv237 Yep, contribution has proven to be injector related for me more times than not. If not injectors, then compression is a likely cuplrit. If you have little to no blow-by, then it's probably an intector or 2

[@onefixitman]

When you say ForScan is free....Do you have to purchase a device that reads the codes and how much is it?

[@ProjectTimeGarage]

First let me say that I'm in the middle of making a full-on tutorial on using ForScan and TorquePro in order to get data and do 2-way communication with the 7.3 and 6.0 trucks. That video should be out Friday the 3rd. Anyway, yes there is a bluetooth OBD2 scanner that I get off Amazon. I have about 5 of these things. Here's the link to it. amzn.to/3ZcKQJB

Is this similar for a 97 F250 PowerStroke 7.3l engine?

[@ProjectTimeGarage]

Yes, almost exactly the same.

[@rickprofit85]

@@ProjectTimeGarage Thanks, Do you have a video on replacing the OEM turbo Ina 97?

[@josedemateo7065]

i cant seem to get that app working on mine 😢, i have a 7.3 that has rough idle, hard to fire up, and white smokes when it finally starts , goes away when i drive it, please help!

[@ProjectTimeGarage]

Likely culprit is Injector O-rings, but there needs to be a lot more investigation before tearing it down, could be a whole lot of things.

[@caseihpopper]

After replacing my turbo I am so not looking forward to this but at least I know my old turbo wasn’t bad 🙃

[@ProjectTimeGarage]

It's actually not too bad to do.

[@marcgreer5770]

What software or device are you using at the end of the video to monitor the hpop pressure? Thanks, great video

[@ProjectTimeGarage]

The software is called Torque Pro, it's available on the Google Play store. The OBD2 adapter is from Amazon, there is a link in the bottom of the video description box if you want one.

[@marcgreer5770]

@@ProjectTimeGarage thank you! I truly appreciate the info you are putting out there!! Big help!

[@rodneyberg1271]

Say we were not able to find forscan program. Any help

[@ProjectTimeGarage]

Yep I have a full video covering the basics of this. Have a look at my videos, it's there within the past 6 months or so

[@johnson7454]

Any way to tell if your cups are bad? Besides just replacing them

[@ProjectTimeGarage]

The typical sign of failed cups is diesel fuel in the coolant.

[@johnson7454]

@@ProjectTimeGarage awesome thank you for taking the time to respond

[@emilyblackston6620]

Cant find the forscan app. Can u show a pic or help me find the app?

[@ProjectTimeGarage]

Have a look at my other videos, I have one that covers Torque Pro and Forscan, along with setting it all up from scratch.

[@TheDogsBox]

You made no mention of the brass cups inside there, what mileage do you need to be concerned with replacing them?

[@ProjectTimeGarage]

I have a 2 part video series on the cups. Basically, I don't change them unless there is a reason. Most common reason is diesel fuel in the coolant.

[@mrgearhead5087]

Very help video. Greatly appreciate it

[@ProjectTimeGarage]

Thanks!

[@gregk6668]

I found there is a place here that fixes and recalibrates fuel injectors. Friend said it cost him around $100+ to have his done for his 4 cyl car. Thoughts on this type of service?

[@ProjectTimeGarage]

I'm skeptical that they'll rebuild the HEUI injectors for that price. The repair parts alone for those injectors is WAY more than $100.

[@gregk6668]

Great video BTW. Thank you for sharing your knowledge with us.

[@timothysheets8613]

Great video. Can you send link of reader on Amazon?

[@ProjectTimeGarage]

That reader was discontinued I think. I've looked for a repacement but havent' found one.

[@barrykozak3536]

I'm getting one of those obd scan tools. My truck is having some similar issues. Thanks bro.

[@ProjectTimeGarage]

No problem 👍
