- Eric here with Pro-Rebuild back with another video. This time, we showcase our custom Ford EEC-IV ECM/PCM Engine computer tester! This testing rig allows us to test several key circuits inside these failure prone PCMs to both verify condition and prove our repair! This applies to
1991-1995 Ford F-150
1991-1997 Ford F250 and F350 Gasoline only
1992-1996 Ford E150, E250 and E350
1993-1994 Ford Ranger
Many common symptoms of a bad PCM in your vehicle would be:
-Cranks no start
-one dead injector bank
-Fuel pump stuck on
-Won't idle
-Check engine light on but no codes stored.
-Improper reference voltage
There are some other less common failures but we cover as much as possible when testing these.
So you think yours is bad, and you want a new one, what do you need to know before you buy?
As mentioned in the video, the part number is paramount! This part number identifies both the year and model, along with the engine, transmission and calibration. The part number is found on the white tag on the connector and will look something like "F4TF-12A650-PB".
If your vehicle has an aftermarket remanufactured pcm, theres a good chance the part number will be missing from the pcm. Sometimes, you will find the 4-digit strategy code on a sticker on the door jamb, or on the cowl depending on your vehicle. If none of this information is present, please contact us and we'll try to narrow down your search.
Many of these are VERY hard to find, and we are often out. In some cases, it is possible to repair yours.
A multimeter or a volt meter will get you very far in diagnosing a bad pcm. Hope this video helps and if you're looking to purchase, we can be reached at:

Thanks for watching! - Auta a dopravní prostředky
I'm working on a 94F150 been throwingO2 sensor codes, out new sensor in an still throwing a 173 code. Gonna do some more checking and if can't get it will look at ECM an give y'all a call, been a subscriber for a while now and love the teardowns!!
Great info for a 7 min video, especially the info on just buying one online, that says its fits your vehicle.
This is cool that y'all's doing this love it.. I've got a few of these trucks and I put a computer from a automatic in a manual and has worked for over 15 years. The check engine light is on but no issues running or driving. They were the same motors at least lol. I wouldn't have even tried to do a manual to auto but other way around ship it lol.
I want to replace my cab on an 89f250 with a 94 f150 I’m wondering if my email from the 89 will plug into the 94 cab? Any thoughts?
Just wanting to make sure you are still in bussiness. I'll be calling you gor an ecc tomorrow.
Thought this was a solid company after watching the video, you seemed to really know these ECU's in & out, however, after calling/emailing I can't say I'd recommend your services to anyone.
I watch you all the time
Why?
I saw your s10 6.0 video 👍
Hi Sarah, I’m really not sure if you’ll even see this reply or not but I have a 1994 manual ranger and when I bought it its always had an issue with the ecm where it just will not start after driving/turning the ignition too many times in a day and I’ve tried ordering a new ecm and it made it run awful and so I had to put the old one back in, when I opened up the old ecm when I had it out I took some pictures but nothing appeared to have a bad connection or no capacitors leaking, I’m really not sure what it could be and I have no clue how I could find a perfectly working ecm that’s exactly for my Ranger stx 6cyl 4.0 manual, seeing your comment on this video and watching your ranger videos you made made me assume that you had a similar problem with your ecm, I was wondering if you have any input you could help me with? Thank you in advance if you do end up finding this
'91 Bronco, 2 of my Caps leaked and cooked my transmission over 1 year of driving it. Early Torque converter lock up was the only major clue that something was wrong.
This is an awesome video.
I have an 89 E150 with 70,000 original miles, when starting warm it has a pulse idle for a few minutes then smooths out, but cold start it operates like new. I wish there was reprogramming for extra power like there used to be, I've been wanting a replacement ECU for when mine shorts out in the future. I have a 600 I/6 with the C6 transmission
This is amazing!
We have a 95 Power Stroke that is having throttle issues. First time it revved up all by itself with no one in the truck. Now about every half hour it starts rattling smoking, and looses all power. We were scanning it thru one of these episodes and the injector pulse width goes from 1.2 to 5.5! We tried a rebuild IDM and it won't even start. :D
@Pro Rebuild - did you guys ever do a video on the diesel test kit I didn't see it on your channel? Do you know where I can find a PCM harness wiring diagram for a 1993 F-350 7.3 IDI Naturally Aspirated 2WD?
We got these EEC IV in our
E series falcons in AU
I got a no start problem with my 94 f150. Do you know what would cause my truck just to click at the solenoid when I try to start it
Could this cause only 6 of the ignition coils to spark and not the other 2? 1998 ford f150 4.6l v8 4x4 single cab stepside shortbox
Does the Module control Shifting in an F150 with Automatic Transmission?
I have a question, I have a 97 ford f250 f7tf-12a650-rh
will it be compatible to a 2001 e350
1c2f-12a650-ahc
So are the pcm plug and play if you get the right one?
I would love to be able to tune one of these and modify the firmware to reuse inputs and outputs like they do with hondas
Where is your store front on the internet. How much is a rebuilt?
B K Brown in Knoxville TN
Could a bad pcm blow the fuse for it?
We just bought a 1990 F150. But we don't know which computer is compatible with it. Need help with serial number
Where can i get one of these for my 91 f250 7.5l e40d?
Hey tool you use to test ecu its aweson, vendes de ese tipo de herramientas
Can it cause fuel pump randomly stop working?
Where do you buy the capacitors that need to be replaced?
I have a 2003 f350 6.0 diesel. It uses ford protocol for an operating system. It uses canbus for the ficm control. As i understand it, this ecm was only used for 90 days. Im having trouble finding troubleshooting videos for this ecm and system. Can you assist me?
What if I changed my rear end from a 308 gear set to a 355 gear set Will that affect my transmission
Olá preciso de ajuda meu clubwagon e350 está falhando muito já troquei os injetores e verifiquei todo sistema elétrico, estou achando que o problema está na pcm
how do i get one of those ecm pcm engine computer tester
Ok little study here 1990 f250 7.5L gas battery was installed backwards by customer now we’re getting irrational fuel pump relay activation and constant coil firing without the engine spinning could an internally shorted ecu cause that ?
Can we still expect a video for the powerstroke computers?
Where are you guys located out of and is this true only for 90s trucks. I currently have a 2000 excursion and I've been chasing my tail trying to figure out check engine codes. A mechanic shop couldn't diagnose it recently and I'm starting to thinking it's my engine computer. Please let me know how I can get in touch with you folks or if you know a reputable shop in Southern California, thanks in advance 👍
Where is the computor located?
I got a PCM on my 91 Ford f350 7.5 thats FOTF-12A650. Can put a different PCM or does it have to be exactly the same?
I got 95 F350 7.3 powerstroke auto trans not working correctly please help mechanic said bad ecm or intrment cluster or both
Do you have any for the 80s
Do you do repairs on the pcm an idm?
Hi stupid questions time. I have a 1994 f150 l6 5 speed.Last year during al this covid stuff I lost the fuel pump part of the eec.
This a ca. truck according to the emission sticker.Instead of using the info on the door jamb< I pulled the eec and showed it
to the local auto part chain store to have them match it.Can a manual trans truck run on a auto eec ? supposedly they matched the eec.
door jam says F3AE 6E081 HHD.Calibration 3-51-R10. old eec the one I pulled out says F3TF 12A 650 NC.
I believe they tried to match by application . I could never get the idle below 1000 rpm.Lately on start up hot or cold idle swings up to 2000 rpm then drops to 1000.Check engine light works and is not on.Passed smog a week ago.
I dug up my old OTC 4000. It can do the KOEO test only and comes up with all kinds of auto trans codes Will not communicate when I try to do KOER or select show data . I clicked on path finder the help on the scanner . I get just because your vehicle runs on this eec doesn`t mean it is correct for application ?.
Any advise on how I should proceed ? Thanks
How much everything does these PCM control in a engine for 91 Ford f350 7.5?
I have one that needs repaired how do i go about sending it to you
Do you sell those boxes to plug in computers? Im in Colorado
Where are you located can I send in my ecm to be rebuilt?
Do you have computer for sale for 1987 f250 5.0 liter automatic?
Where can i buy one? Need one for a 1994 f150
Im searching trying to find a way to contact you to send you my pcm but I cant find contact info anywhere.
How much do you charge for revuilds?
Where u guys are located
I know you haven’t answer this question, where can I find you guys.I would like to buy one
How do I contact you? I need (at minimum) technical advice
Where are you located, I have a 2 ECM to repair please?
Were is located
Are y’all still open
Where you located
Where are you located?
What about a 89bronco xlt
So i ran my 1999 7.3 powestroke out of fuel. Reprimed the fuel bowl and everything and its getting fuel but its crank no start. Would it be pcm?
Did you ever get ur truck started I know when I changed my hpop it took for ever to start it takes a lot to clear that air out of the system so
question, could a bad ecu cause a trany to up and down shit sporadically without any warnings? either at low or hwy speeds?
94 bronco owner here, mine did that yes, it would hard shift and according to the mechanic it would be shifting from first to second but it would think its in nuetral and cause it to jerk and shift like i got hit by a train from the back, hope that helps. Its not a absolute but from my experiance it could be the ecu is going. I THINK its either water getting in from the rotting body seal in the cowl amd dripping on the wires or just goes bad naturally
Why do you not answer the people?
Is there a way that you can get one of these stock computers and upgrade all the capacitors and resistors and what's necessary and reprogram it to be able to produce more horsepower or they just easily able to be hooked up to with the right stuff and reprogrammed
We do not do anything like that. We just do stock replacements no upgrading for more horsepower.
What numbers do you want? When I type in all the numbers it has no matching parts. Here's everything it says, JETO eec-iv efi-sd48b f4tf-12a650-na g 64esb48b37 9573-10 4a31, by the way it's a 94 ford econoline with the 351w
would you repair my original factor computer and ship it back to me ? thank you
Eric, I need a PCM for my truck and I had tried calling the number you have listed in the description to find out if you had one available and see if I can purchase via phone but I get a recording that this number is not available. Did you change numbers or what’s up brother? I checked a couple times and what I dialed is exactly what’s in the description. Can ya please help Eric, I need to get my truck running, my feet are tired of walking! Lol
It’s a 1994 F-250, automatic transmission. I’m gonna pull it in a few hours and hopefully it will still have the part # decal on it, but we’ll see.
Thanks Eric!! I appreciate the help !!
Did he ever answer you? It looks like nobody gets any answers here...
How can I send you my computer it’s for a 93 f150 I have all the part numbers and what is the going rate to get a repaired unit thanks?
Ever get an answer?
Are you still in business?
Great video. ! I have a 1993 F-150 which cranks, but doesn't start. Replaced distributor, coil, and the computer twice. Truck will start & run for @ 30 minutes, then die. I bought a tester from Amazon, but for OBD 2. I assume Amazon has testers for OBD 1. Suggestions ?
Same issue here, i got a 30 dollar obd1 tester at autozone and i got the code for PCM Voltage failure (Code 513)
@@jacobog3221 What did you replace, and did the truck run OK then ?
They do, just got one myself
@@kennethcallahan7410 Tks
Do you have contact info so I can send you my pcm??
95 F250 7.5 Automatic. Starts fine idles with a slight miss, runs fine as long as I don't stomp on it. As soon as I stomp on it, severe misfire, rpm drop, harsh jerking and rich exhaust. Timing light on coil wire confirmed coil is not firing when misfire occurs. New distributor, plugs, wires, coil, ICM, MAP, fuel pressure regulator. Previous owner was chasing this problem. Drive it 8 hours home as long as I babied it no misfires. I'm down to ECM or timing chain. No check engine light. Have you seen this specific symptom?
Check TPS, might have a bad spot on the potentiometer. Then check ECM for bad (usually leaking) capacitors.
HOU MACH FOR A PCM FOR F350 DISOL
94 bronco 5.8 I always smell a plastic burning scent from the ecm location for 2years now. I get paranoid I check the brake reservoir which has been updated and some times think its the rust protection burning. Now im sure its the ecm burning its self. I wonder the cost probably like 600
It's possible something else is causing the smell. If a capacitor was getting that hot it would have gone out a long time ago. Our units are much cheaper. You can find them on eBay by searching your part number.
@@ProRebuild thanks
That's a great video. How do I find your address.
went to your website no ford products!!!?
how do i get in touch with you? i went to your web site but couldn't figure out how to contact you from it
Did they ever answer you?
Can I pay to test mu ecm?
Can you repair PCM out of a
2002 7.3 4x4 4D
VDH2 2C3F-22650-DC DPC-462
Did u get ur idm or pcm fixed?
Cost, for 1995 f150 XLT
5.0 2wd.
I have one for sale contact me on facebook Tommy Kite out of known running truck
nice video, to bad no one answers the phone, or email......
Or I guess affect my ECU because of the speed difference
I need one f4tf. How much?
There is a lot more to the part number the that. Please check out our eBay listings and match the FULL part number.
Do you have a email address I can contact you at? I am have several problems that all point to the ECM (constantly running fuel pumps, no start, and leaking Capacitors in the ECM) i have pic of the label but I can't make out the part number. The truck is a 1994 f150 XL v6 with Manuel trans. Thank you
was the constantly running fuel pump a capacitor problem?
@@TropicBreezeRealty i took the ECM to a TV shop and had them replace all the capacitors that were bad. After putting the ECM back in the truck all the same problems were there. We replaced the entire ECM with one from O'Reilly auto parts and the truck fired right up. ZERO PROBLEMS.
I just pulled mine out of my 1995 Ford Bronco with a 5.0 motor and it has a little black plug in of something on the back side.
What is that and why is it different than all the other ones I could find online ????
You need to come up with a test for the trans. I just installed the 7th computer in my 95 lightning and 3 we reman. The last used computer fixed it.
We never sold you seven ECU's. I do not think we have sold you a ECU. We have not had a Lightning ECU here in a long time.
@@ProRebuild I don't think he was claiming that he bought the seven ecu's from you, only that he bought seven.
@@jimmydavis6254 Could be true. They can contact us by phone if they are having any issue. We will be happy to help.
Oh and I also got to say this man it's not 100% critical about the matching identification numbers lol not joking my computer every so many months will fry itself the ignition control module or the coil rarely but I could not keep spending $200 so I found computers that were relatively close to what I have you know v8s same firing order relative same year you know keeping it close and well I've got one in right now I've got another one under receiving my truck and I'll probably went through about three more and I'm trying to find out what is making it burn blow before you're seeing anything I have put in probably $2,000 worth of new and remand computers The trucks got a lot of sentimental value to me so I'm stupid and don't want to let it go That's why if you look a little further down in the comments just send me asking about upgrading the computers by replacing all the parts inside to see if it can make more power
Yes some computers will get can get you running but are not the correct ones, matching part numbers is the best way to make sure it works.
the calibration code may also define if it needs a push-start or tfi ignition module in the years of crossover. the PIP signal and what goes to the ecm or from it. But, the wiring pinout is NOT The same and the pcm can very well nade a module and coil or the module sends something to the PCM on the wrong pin, and its also without the resistor that the other system has.
SOOOOOOO
You need to get a proper TFI or Push start module (black vs grey) and also MATCH to your PCM calibration on the truck and make sure it matches the drive train, THEN any updated cals from Ford
also a c6 computer wont do very well in e40od since brake light circuitry is different and the pcm is not worried about shift points... also cruise being on the system affects how it reacts to certain inputs and in a c6, the manual tv valve controls line pressure and it controls parameters TO influence line pressure through different means than where it can use the epc or in the 4r whatever, its got more than e4od.
point is match your year range usually 91-93, 94-95, 96, 96-97(F250 HD only), emissions commie or states, drive train in its entirety, chassis similarity like no C&C in a step side , air density / maf, vin cut off in relation to tsbs, some may cut off really weird spots even same year trucks,and then sure you can if its similar. the problem with eec iv is how universal the base components are which is why its also so cool and desireable. The things that might mean BIG from one to anoter arent able to be self-diagnosed with regards to components, its not meant to discriminate severely and its also capable of seeming fine when its costly damaging. the data reading is low, and its not tracking long term trends quite like they do now, etc. So sure you may have good AFR but you forgot your new pcm wasnt at all able to handle Secondary air, so now your CATS arent doing their job and they gonna burn out. smooth. or your bad throttle cable does not move the throttle enough for the outdated cals to notice the rapidly wiping signal from TP sensor and 1 sensor wears out 2 you have fuel enrichment happening as intended yes but now your truck is having a hell of a time handling shifts well, keeping temps low from TCC unlocks, and pass emissions from fuel trims up and down.
get the right pcm and get it updated
ford didnt put calibration codes out there for fun or because they like stickers(which they do indeed like stickers)
@@CT_Taylor Thank you for what you wrote that was interesting and it did helpyes I do have the wrong computer in and other things probably aren't up to snuff because parts have went out so often but with a factory matched computer put in it we'll still fry those components
@@CT_Taylor you are absolutely right.... Lol could go without the grilling at the end.... Lol
Man this a constant problem with a matched ecm. U get to the point where I LOL CAN'T spend anymore $$$ on these???? My question is how, what, where's, a place I could look at to see the problem. Or something like a process to do to make this dam thing stop THIS 🤦🤦🤦🤦🙏🙏🙏🙏🙏🤞🤞🤞🙏🤞🙏🤞🙏🤞 anyone...
ASK me some questions about the situation and truck
