Ford ECM Repair EEC IV | Fix Multiple Issues | 1980-1996 Ford Bronco F150 | Bronco Restoration

[@rebelspohn]

Bro, I am literally crying. I have been trying to diagnose my 1992 f150 5.8 for almost two years. Have replaced basically every sensor, wires, hoses, etc. I've read hundreds of forums trying to fix this rough idle, intermittent dying, zero power, absolute BS running rig. You're my f**king hero, man. Thank you, thank you, thank you!

[@Matt-vb2jo]

Same here on a 92 150 starcraft conversion. Talk about a freaking nightmare. Replaced everything like that. Finally wised up pulled ecm and opened it up. All the capacitors were leaking on chipboard. I'm researching now how to get the right one.

[@Matt-vb2jo]

Update put new ecm in and she runs like a top, Minus a small coolant somewhere but it completely took away the transmission shuddering and missing also.

That's the cleanest 1990 bronco I've ever seen.

[@TheFixTech]

Thanks

[@OliverKoolO]

Right super clean

[@So_called-v1j]

There is this kind of satisfaction to watching someone that knows what they are doing. Also working on clean components is fun to watch. Thank you for the video

[@TheFixTech]

Your welcome

[@jamesstufano1504]

Hi … just wanted to say very well done. My truck (1995 F-150 XLT) started randomly stalling on the road. Mechanic did fuel pressure, changed fuel filter, added sea foam Seemed to be running better but still rough at in the beginning and today driving a couple miles, it stalled again. Started reading forums and owners with the same problem mentioned the EEC. Your video really explains things and last, you have one clean looking engine.

[@newageguitar]

Flagship 1 charges $550 for a rebuilt (or what they call refurbished) ECM for a 93 Ford 7.5L which my Winnebago Brave has in it’s Ford F53 Chassis. It’s very slightly different but your fix is the same. Was running horribly, no idle and shut down intermittently. Engine is now jet smooth again including the shifts. Cost me $7.75 with 8 spare caps of each (same as yours) and a bit of time. Your video is superb.

[@TheFixTech]

Thank you.

[@RoseBaby]

We appreciate the quality of your videos with the clear instructions. Thank you for posting!

[@growth_mind_set]

Dude. I have been watching your videos for some time now--and others. You have the best (in my opinion), the most forward, knowledgable and comprehensive way of explaining and demonstrating how "fixing" our vehicles is not scary or really complicated. Thank you for your efforts in creating this content. Liked and subscribed!!

[@TheFixTech]

I appreciate that!

[@TheFixTech]

You can save good money doing this repair. If you are new to soldering, I do recommend practicing beforehand

[@layzorbeeemz7317]

hey dude, ever come across a bouncing serpentine belt tensioner? mine was doing that so I replaced it with a new part and it still does it... recently I replaced my alternator with a 130A 3g alternator which has a slightly smaller pulley, I'm wondering if it is as simple as needing a slightly smaller belt.

[@bryanblake8607]

This actually answers why my 96 f150 is acting odd even with replacing the pickup coil inside the distributor, seeing I am pulling the motor next moth to install a new cam and few things this just got added to the list

[@TheFixTech]

Unfortunately the 96 is different as it uses an OBD 2 ecm not the EEC IV. Use a good diagnostic scanner to check for any stored codes and run a live data check. You should be able to check all parameters in real time, fuel trims will tell you a lot.

[@badasspearldrummer]

Bro! I’ve been chasing some problems on my 91 f250 for ever. It hasn’t run in a few months but I just did new injectors and a new dizzy. Still not running right. I came across your video and said what the hell. Pulled my ecu and sure as shit, 2 of the caps were leaking and one leg was not making contact on 2 of the caps.I didn’t bother with doing it myself and just ordered a new one. To say the least I think your video saved my ass. Thank you for making the vid. New ecu comes in this wed and I’m pretty sure she will run great. If your ever in so oregon I owe you lunch😂

[@trustme7731]

And?

[@jeffreyyoung4104]

When it comes to replacing electrolytic caps, you can use higher voltage caps. As the original caps are 16 volts, and the car works at 13.8 volts, you are running close to the working voltage of the caps. I would use 25 to 35 volt replacements, as the new caps are actually smaller now with the higher voltage rating. The capacity of the caps, 47 microfarad is more important to keep as close as possible, and 47 UF is more common than 50 UF caps were in the past, but if it was a 50 UF, you can use a 47 UF as a good substitute. The one thing that takes a toll on caps is age! They have a liquid inside that can dry out, leak and corrode the board, or the unit may short and cause tracks to burn! Which is why there is a home industry repairing old electronics by replacing the caps known to fail due to age. The temperature rating of the caps can also be increased without worrying about failure. I use 105 degree C caps as often as I can, there are higher ratings, but the cost is also a factor, so don't go overboard in increasing the temperature ratings too high! One thing about soldering, be sure you use an iron that is grounded and does not cause static burnout of components. If you don't pay attention to this one fact, you can burn out semiconductors and cause more damage to the equipment.

[@thisisyourcaptainspeaking2259]

Good video man, this is real. Also, the death wobble caster bushing to add a couple of degrees of caster if you run into wobble. The front coil springs are known to sag over time as well, causing camber issues.

[@lang8177]

Thanks for the video. I just did my 95 Bronco XLT E40D-4WD 5.8L; I got the Nichicon FG Capacitors and a Weller 60W Kit from Amazon, I got it in and had it running twice with no issues. It feels like it's running smoother as well.

​@@Untamed_bronco...What he used is in the video description with a Amazon link...

[@RGUNS88]

Thanks for the motivation and guide. Just did an ECM replacement with a remanufactured part on my 1993 Ford F-250. Similar but different on removal/installation. FYI for those about to do the same, the ECM is pulled out through the firewall from the engine bay, not the cab like in the video. No reason to take off any trim in the inside to figure that out. However, the ECM unit is too long to pull out without running into the wheel well so I removed the back half of the driver side wheel well screws to give it some flex to get it out. Thanks Ford engineers for that easter egg. Anyways, computer is in and the electrical gremlins appear to be gone. Good luck everyone on your projects!

[@TheFixTech]

Great information.

[@randallcarney1216]

Thank you

[@OCtheG]

+1, had two shops in a row fail to diagnose and after replacing every single sensor myself I finally have it narrowed down to a main ECM problem

[@digitricks]

Thanks for the the well-informed video. That may be what the problem is with my grandpa's 91 Crown Victoria! BTW, uF is the abbreviation or symbol for microfarad, a unit of capacitance.

[@vinny2597]

Thank you so much for the info...!!!!this video was superr useful!!!greetings from chihuhua mexico

[@severespecialist6781]

thanks for the vid. gonna check my 95' broncos capacitors!

[@steveh7108]

What did you find out about your 95 Bronco capacitors ? I think I am going to have to attempt this project on my 95. It runs great but sometimes I shut it off to run into the store and come out and it just won't start again for a half hour or so. Thought I had it fixed by changing out the ignition control modular and it seemed to run great for about a month and then all of a sudden it did the exact same thing. Then after a while of trying to start it everything went completely dead even the dome light. Came back the next day and disconnected the battery to reset the computer and it seemed to start right up like it never had a problem.

[@murphytoadster9864]

I gotta check mine. My f150 had lots of leaked capacitors but it didn't affect anything that I could tell wile running and driving. My bronco is the the mystery problem

[@jcataclisma]

Well, sir, this video is just pure gold! Thank you very much!

[@TheFixTech]

You're very welcome!

Dude this was super helpful! I have a 96 bronco now and used to have a 90 that I loved as well!

[@Rico24337]

Awesome video, super easy to follow and understand.

[@psyfusion]

Nice video, I got a super clean 1993 Glaval Universal E150 conversion van that’s having some awkward issues that apparently has cost a family friend hundreds of dollars to no avail and was given to me to solve it and since it’s mine if I do my motivation is high. They replaced the sensors form transmission to the cluster and nothing ever fixed the bouncing speedometer and rough shifts and I’m certain now I have a capacitor issue after this video. Great work and damn nice bronco

[@TheFixTech]

Be sure to check all speed sensors, your truck should have three, one on each front wheel (abs) and one on top of the rear diff. Does the overdrive light flash?

[@psyfusion]

@@TheFixTech all three replaced and The od doesn’t flash but the air bag does, after replacing all three sensors it worked for about a day and then it was back to the bouncing speedometer and The no shifting into OD it down shifts and throws itself into limp mode. Speedometer works and shifts are smooth until 45, shifts are good until 55 but after 45mph is achieved it begins to bounce between 45-55 and every mph closer to 55 I get the wilder and more eradicating the bounce.

[@ferratilis]

Man you got an absolutely mint Bronco. Thanks for the vid.

Nice. I appreciate all the info

[@stur.7502]

God bless you! That is one nice Bronco! Thanks for the knowledge, going to do mine while I'm down for maintenance. Your an excellent instructor, simple and well explained, especially the detailed capacitor notes! Now I can order before tearing into everything.

[@patricklitwin975]

You're the man! Thanks for sharing.

[@TheFixTech]

Your welcome

[@jrorellana4865]

Thanks for the great video, my ECU needs new capacitors but I am having a difficult time melting the old solder and removing the old capacitors' leads. I am afraid to keep the soldering iron for too long and damage the circuit board. You make it look so easy, what is the temperature of you soldering iron? Thanks

[@TheFixTech]

You can try to cut the capacitors off, then use a flux core solder and melt a little on top of the old solder to help soften the old solder. Use tweezers to pull out the leads. If you do not have flux core solder, use flux paste. I usually set my temp to 600 degrees, but it can vary from machine to machine.

[@shano92107]

Solder sucker works well for this, basically like a turkey baster but spring loaded so it pulls the liquified solder out instantly

[@mikerodr]

Use Solder Wick to suck up / extract the old solder ; Use a good quality Weller ( WE1010NA ) soldering iron ; that means no HARBOR FREIGHT JUNK ; Also its preferred that you use an anti static mat designed for electronics repair that is grounded ; other wise you could zap the electronics with a static discharge.

[@steveh7108]

That sounds like good information. Where would be the best place to get that soldering iron and any other good soldering supplies that you spoke of? As well as the "Panasonic new production" capacitors? It seems like nowadays you could buy new tools and parts and they're junk brand new and there's no way to know for sure.

[@BI0L0GYN0T35]

Chris Fix got a new channel?

[@ReptarART]

Nice bro hopefully this fixes my idle issue tried everything but nothing works pretty sure it’s this thank you 🤟🏽

[@rs3097]

I would suggest going with electrolytic capacitors rated at either 25v.or 35 volts instead of the original 6.3v and 16 v. It's just added durability and the physical size is the same. Be sure to disconnect battery first before attempting this.

[@mariopalomera3016]

Damn bro, you have the best Bronco content there is out on the internet!! Had a question, how did you set the idle voltage on the throttle?? Do you have a video out there how you did it?

[@YammiePro]

Nice, thanks for the info man!

[@fca4821]

Excellent DIY Video..I think you did a great job making this video. However; Don't know what year your Bronco was, but it didn't work for my 1994 Bronco XLT 5.8. After removing the drivers side kick panel I could clearly see it didn't match your video and there was no-way the EEC-IV was coming out from the inside. Mine had too removed from the engine compartment of the drivers side fire wall. So for anyone doing this, double check to see if your EEC-IV is removed from the inside side of the fire wall or engine compartment side of the fire wall. Nice looking Vehicle.. Don't know what year your Bronco is, but looking at the vehicle photo I'd guess it was a 1993 or earlier.

[@jamesr.schroensr8361]

[@andrewballance7249]

Zow! Rub some of that smart off on me. Thanks super tech.

[@subcoolman]

Nice video, but at the 5:30 mark, you can usually get better results with a solder sucker ("desoldering pump") than a wick. I've re-capped a bunch of old jukebox tube amps, and wouldn't do it without one.

[@TheFixTech]

I do have one of those, bought from radio shack years back.

[@archie34734]

Thanks for the great tutorial on how to remove and replace the ECM (TCM for my 1993 7.3 IDI diesel). I've installed two OEM TPS's and when setting the WOT voltage when opening the throttle toward WOT at 4 volts I get a momentary spike to 6 volts throwing the voltage way above the required 4.5 volts WOT setting recommended by Ford. This of course throws an error code causing the truck to go into limp mode. I had the exact same error when both new TPS's were installed. I figure if the issue is not the TPS the problem has to be in the TCM. Because when I'm setting the TPS voltages the truck is only in a key on engine off state.

[@daviddarkside1079]

Thank you my 89 has that ruff idel and shifting problem i already replaced everything rebuild engine transmission and transfer case now its charging the capacitors

[@theobrown1309]

Is there something else I could plug into that connector? Like and aftermarket engine management system that won't break.down like this?

[@TheFixTech]

I am not aware of any aftermarket ecm for these models. You can purchase a refurbished ecm from Rock Auto, be sure to match yours exactly as there were several different models. There will be numbers on the ecm itself that should match one of the Rock Auto listings.

[@jameshornsby8969]

thanks for the info I have the same bronco

[@murphytoadster9864]

Mine is a bad cold start issue. And weird misses. Even when fully warmed it wants to stall if I rev it up a bit. Replaced every sensor and part except O2 sensor and ecm. Confirmed perfect fuel pressure.

Check the distributor pick up coil and ignition module

[@normanward9423]

Excellent job

[@TheFixTech]

Thank you very much!

[@EdreihAldana]

Thanks a lot for the video! My capacitors went bad and I replaced with this tutorial. However the erratic idle after starting the truck hasn’t gone away lol I’ve replaced the IAC valve, TPS sensor, and MAP sensor already…. Any idea what else to try? 😅

[@TheFixTech]

Check for vacuum at engine idle after warm, should be at least 15psi depending on altitude. Vacuum leak can be intake gaskets

[@hotrodgavin6543]

Thank you so much man i'v been struggling for 5 years to fix my truck it's been having transmission issues with shifting I found a shop last year that told me there is no signal going to ECM from Gauge Cluster all the trans shops around here have told me I need my transmission rebuilt when it has nothing to do with inside transmission it's been electrical I pulled out my ECM all 3 capacitors are leaking and I think it's like a fuse thing it's rusted bad

[@TheFixTech]

Depending on year of your truck, 92-96 will have a PSOM speedometer, these do go bad and will either need a replacement or rebuild usually around 80-100 dollars. If your overdrive light is flashing then this is likely the culprit. Try the capacitors first as they do need replacement, then look into the PSOM

[@hotrodgavin6543]

@TheFixTech I put in a used one and my transmission was shifting fine for a day then started acting bad the next day

[@jarryrustics4482]

Great video. I assume this applies to 5.0 as well? I have a 1990. I have seen other videos showing loosening of the wheel well cover as opossed to the kick plate. Your way looks easier. Thanks, Steve

[@TheFixTech]

Yes this will work with the 5.0, the 1992 and up (obs style) require removal through the fender well, I have done it without complete removal of the fender lining, just pop out a couple screws and the lining will bend out of the way.

[@Christlover88]

[@flash21502]

Hello, I have a 1995 f150 with 5.0 v8. I saw another video where the guy took out 2 bolts in the firewall above and below the pcm connector and pulled it out that way. Can mine also be removed from behind the kick panel like you did on this Bronco? Your way looks much easier. Thanks for the great video!

[@TheFixTech]

The 92-96 generations have bracing inside the kick panel that making the ecm from the inside difficult. For those models it is easier to remove from the engine bay.

[@RGUNS88]

See my new post above for my experience.

[@elevationtransport3753]

You should try to take better care of your bronco man. Lol absolutely beautiful truck! Great info also. Very cool. I have a 1990 that is a dedicated off road rig with the same issues. I will be excited to give this a shot

Well worth the effort, I noticed smoother performance all around.

[@doctorantivirus.]

Good video as always. I have problems with the parking brake, do you have any video of that?

[@TheFixTech]

Not yet, depending on the year the parking brake has an adjustment under the driver seat, under the vehicle. I have a video on the rear drum brakes showing how the parking brake cable routes inside the drums.

[@krisdphillips]

My 1995 F250 7.5L has been stalling out at red lights or when slowing down. It runs perfectly when going down the highway and has no issues when cold, but once it warms up and I go to make a stop, it will 5 times out of 10 stall out and then fire right back up again. I just got a scan tool so I can work on testing it later today, but I'll add this to the list of things I should check. Have you ever seen a bad ECU cause stalling like that? I'm also wondering about the IAC, MAP, and ICM, but I'm fairly new to these older trucks (I'm used to ODBII and having a scan tool to pull codes when something goes wrong).

[@TheFixTech]

Check your egr system, verify your egr valve is not stuck open as these are common symptoms of failing egr. Also replace both fuel pump and ecm relays.

[@nicklugo7068]

Hey buddy I’m getting ready on doing this and I’m a little confused on the resistors I’ve gotten vs the one I have on the ECM

[@TheFixTech]

The resistor numbers need to match. The positive/negative terminals also need to be soldered onto the correct side

[@nickpanhead7209]

Beautiful bronco you really maintain it, and it shows. I have an 87 f150 xlt lariat, do you know if the ecm pulls out from the inside as well. I'm just wondering if those capacitors has something to do with my idle up and down, up and down when I first start it. Then, it levels out to a decent idle. Right now, the truck won't start, I have spark, I think it's fuel related dropped off at shop. Hopefully, it's nothing much

[@TheFixTech]

Yes the 1987 ECM pulls out from the inside as shown. Check your IAC valve and TPS sensor for the idle issues first.

[@nickpanhead7209]

@TheFixTech thank you so much for getting back to me. Right now, the truck is in the shop for the no start issue. But I want to check that ECM Capacitors, once I get it back unless that's the problem that he discovers.

thx for responding to my van problem. is it possible for the fuel pump to fail after warmup and then be good when it cools off? Also this van sits for months at a time in the Seattle area, I'm wondering if moisture is a problem. It trashed my distributor as it was corroded on the inside. I'm also curious about changing the fuel filter., and possibly the water temp sensor.

[@TheFixTech]

It’s very common for the fuel pump to be erratic. It is easy to diagnose, when the truck does not start, check for fuel at the engine rails. If no fuel then try to prime the pump manually, apply 12v to the fuel pump circuit (you can either at the fuel pump pigtail or at in engine bay) if no pump sound then it is a bad fuel pump. I do also recommend a new fuel filter and temp sensor as these trucks are old and require maintenance.

Check all your fuses, inside cab and engine bay. Do you see the check engine light with key on engine off? If not then the ecm is bad.

great video and how-to. I have an 1989 Ford Bronco 58l with C6 4x4, do these 3 capacitors affect the fuel pump function? My Bronco won't turn my fuel pumps on- only if I remove the fuel pump relay and jumper wire the hot to the pump will it run them and then I can drive it.

[@TheFixTech]

The capacitors do not directly controls the fuel pump relay circuit. There are two relays that control the fuel pump, the eec relay and the fuel pump relay, they are located next to each other. If the eec replay is bad it will not power the fuel pump relay.

[@kevinclancy.]

@@TheFixTech thanks- well there is power available to the fuel pump relay plug but the signaling side of the fuel pump relay plug doesn’t seem to be working so i figured it was a problem with the ecu

[@TheFixTech]

I had an issue recently similar to yours and replacing both relays solved the problem. If you are still having issues check the wiring, and open the ecm cover, if the capacitors are leaking replace them as they will only cause further problems.

I have a 96 ford F150 with 5.0L that sputters when you accelerate and hold a constant speed would this be my problem to.

That would be an obd 2 pcm and may not have these capacitors. For your situation check your ignition module, it should be black in color, not the gray one. Also check your tps sensor and speed sensor. Any check engine/abs lights? If so run a diagnostic check with an obd 2 scanner.

Any time!

Hey there, noticed that brown line on your thumbnail. Did you injure it lately? If not, you'll want to have a dermatologist look at it. My wife is in medicine and noticed it and it's my duty to tell you! Hope all is well.

I have 1995 F350 5.8L Powerstroke Diesel (Manual). It cranks very strong, no start. I suspect the EC. Is mine located in the same location as the one in your video?

[@TheFixTech]

Yes it should be located in the same place. If it is a Diesel engine check the crank position sensor, I’ve had that issue in the past and that was the problem.

Awesome video, just subscribed! I have 1985 F-150 with the 5.0L. Truck starts and idles fine, but when I put in gear it stalls after driving about 10ft. Changed IAC, MAP sensor, coolant temp sensor, new battery, new ignition coil, and checked timing. Any thoughts on what my issue could be?

[@TheFixTech]

Check the MLPS sensor on the drivers side of the transmission. This tells the ecm what gear the truck is in. If the computer senses the truck is still in park it will not be able to deliver proper fuel trim parameters.

My 1992 f150 is doing about the same thing it cuts in and out and I assume loses spark. Seems to do it randomly But sometimes when I switch to drive. Sometimes I can nurse it home other times it dies completely. The only way I can get it going is unplugging the distributor pick up and plugging it back in I hear a click like it resets something, but it's hard to restart because it floods out with gas. I don't know if it's normal for these old trucks to flood that easy just from cranking with no spark but anyways I changed a bunch of parts and finally took the computer out and the capacitors were leaking and 1 wasn't even attached, so hopefully that's the problem but I really don't know. It also looks like it has an old mouse nest under the fuse box so I need to check for chewed wires. Hopefully the new computer fixes it 🤞 otherwise I will probably just sell the truck. I might check out that transmission thing too.
