FIND OUT If You Have A BAD FOX BODY A9P or A9L COMPUTER 

That vintage 5.0 diagnostic computer is so cool thx for sharing .

Thank you Matt a couple weeks ago sent my 93 A9L computer to get it repair, a week after got a call from Matt with good news, received computer installed it back and mustang started right away running like new, passed california emissions easily. Once again Thank You Matt for your gray job.

Great to know Matt at Fox Resto can fix our computers! Very good video!

I really love the stuff on this channel. I wish there was a guy like this in Vegas. And this mechanic needs his own channel!

Good video! Awesome info onnthe computers and the test equipment.

Great information n its all good just take your time and when you're finally finish it would all be worth it keep up the great work mane 👊🏾

hi! I saw your comment on Cathrin Mannings video! Love the info you’re providing on your channel You are totally crushing it #greatcontent

great video buddy! I love seeing the old diagnostic equipment. It looks like something from the 1800's but heck, if it ain't broke and it works, don't fix it! Also, funny seeing the SSP in "old format" vs. where it is today. Thanks for the video pal!

Good to know where we can get our computers repaired. Worth the time and effort rebuilding a mustang still remember the pride I felt when the starter turned over and she fired up sounds of a engine running not to mention those different smells will always be with. you.

Awesome piece of equipment!!

Nice Matt! It takes time! I'm about 4 years in on my green car and 2 years in on my white car. Unfortunately, I haven't touched my white car since November of last year! Least you are making progress!!

Love the old equipment that's very cool

Matt, ha! This is great! I actually have this problem right now. (Well before I got the engine knock, I'll address it after I sort that out). When my wife bought the car for me, the owner was explaining that to her but she didnt really understand. So for awhile I had trouble starting the car. Eventually, I figured out that I put the car in the on position and hear the fuel pump priming. It would do this for about 15 min. Then the car would fire right up. I replaced the pump and the relay, did all kinds of electrical test lol A few other guys on IG had the same problem. One of them said he changed his computer and it fixed it. He told me to try that. Now that I see Matt saying it. I'm sure thats what my problem is too. I'm going to share this knowledge. Much appreciated. Sorry for the long comment lol

Man, Matt has all the cool tools and equipment! I can't wait to see the SSP fire for the first time! Maybe I can plan a trip up to be there for it.

I’ll be sending my computer in

Yeah Matt needs a shop here in Central Florida

Very cool to see older technology working. I understand that Matt (FoxResto) had to do some work to it prior, but the older stuff was built to last like a tank. Some of these newer scanners are solid plastic and designed to fail. This was a very neat video. I can't wait for the SSP to be completed. I know that you will take us on a test drive.

Good contents as usual. It is going to be a very nice car bud.

"the right tools for the job" so important. That's a very nice diagnostics tool. Does this monitor work for the '86-'88 Speed Density Fox's? That's an invaluable tool. Engine-Motor-thingy looks great👍

Im here champ ✊🏾

Are these guys still doing repairing ECU's? I am glad I came across this video. May be able to get my car back on the road. I'm having the same symptoms he described with the no-start and constantly running fuel pump.

Matt knows his Fox stuff and sometimes Gearhead does too!😎

A bad computer will have you going in circles. I did with my bad computer. Lol

If not mustang week, foxtober fest! Mine is almost ready and its coming off the ramps this coming week!

I remember the old Rotunda EEC tester. How things have changed since then.

I feel like Parzival from Ready Player One would use that computer lol. Such a cool computer. That was interesting to watch!

I have to send my computer to this shop.

Good they change the pump and relay . Because cheap insurance for refurbished computer. I got rid of the factory computer long time ago.

I had a constant FUEL Pump run problem for a week. Now it does nothing. Gonna pull it out tomorrow.

matt and matt😎😎👍👍👍👍👍👍

Matt & Matt---Could one of you give me the site to buy the adapter plug so I could use that on my 351windsored 4-eye? LOL Nice +, to see Matt knows his capacitors from his resistors.

That is a really cool old school diagnostic tool. Quick question is the injector harness from fox resto? I could use one of those.

I have a 1986 Mustang with a faulty computer. Would these guys be able to work on it? I checked their website and it said they work on 88-93 computers

That was a cool computer diagnostic tool it is crazy that he had to fix the computer diagnostic tool so he can fix computers lol.i wonder if there's a diagnostic tool that will diagnose the diagnostic tool lol wait yeah its called Matt 🤣😜👍🏻🚗💨

thanks guys I replaced every thing she run but smoke lots I will try new computer thanks again

iam swaping a 1989 fox body computer for a 1991 computer; any pointers

Hi ,I have 1991 FOXBODY crank but no start , the spark on spark plugs are good and also fuel pressure is good but no power on fuel injectors ( I replace fuel pump, fuel pump relay and coil injection) .appreciate for any suggestion.

Still doing the computer repairs

I have a A9M computer for my 92 feature car I bought a replacement computer but would love to have my original one rebuilt is this something you would be able to do it me it needs new resistors.

Mine took a $h!t about a year ago. Didn't know until last week when i finally took it to a mechanic i know. Cost me $950 to replace! Isnt it plug n play when u get a rebuilt one?

U should get the computer Chip proformeans for the ECU and the Chip for the transmission police interested an msd box it makes the spark plugs and injection fire faster and at the same time transmission shift better

Dang finally 1st comment! Keep the great videos coming GearHead704

Great self. I just got my self one but can’t find a overlay #26. Is their anyway you can take a close up picture of yours? I will be very much appreciated if you don’t mind.

Dude what color is that I’ve been looking to paint my notch in it to look like the one my dad had when I was a kid

That was pretty cool tool!! I see cream is gone that's weird cause my 92 GT when I turn the key on the on position I don't ever think I heard the fuel pump I just prime it 1 time in the car starts right up the second turn of the key I might open the hatch up to see if I can hear the pump!! But my computer seems to be working fine cold start it idles around 1100 rpms maybe a minute or so it drops down to about 800 rpms dosen't bounce up in down!! Like I said before I haven't ran the car in over 2 years put a new battery in it turned the key once second time she fired right up for me did it's thing idle dropped down no surges or ruff idle in that surprise me I done cleaned 2 rats nest on my motor but when I get paid next week I am going to buy some rat poison blocks try to get most of the nest out it's hard cause of the upper intake try a shop vac in maybe a hose spray it out!! I wish the frame rails wasn't rotted out it's not a bad looking car the motor runs really strong! But I can't afford to fix it when u live on SSDI it's kinda hard that's why if I want a V8 notch a 4cyl 1 was the best option for me I mean I basically have a donor car in I have the whole 89 MAF engine harness I source out a really nice o2 harness it's the with the loop in it what is pretty cool about it u can just move the loop wire u can pin it to be used for a auto trans or manual trans but it's pinned for a manual trans I believe it came from a 88 California car when they started with the MAF! But I have a 89 head light harness I didn't want to take the chance on just extending the alternator wires all the way from the driver side to the passenger side on 4cyl cars the alternator is on the driver's side in I rather not take the chance of not the right size wire in my car catch fire after all that work! Even though I still have to wire it for the 3G alternator in the 130 amp fuse block! But like I was saying I wouldn't be able to afford a nice V8 notch prices are crazy but I had a really nice 87 4cyl notch fall in my lap for a few grand in some hard work I should have a pretty nice car when I get finished with I don't care if it's a original V8 car I will be paying 4cyl price insurance lol!! Maybe 1 day I will get down there to meet u in u can see the never ending project lol I am just waiting for it to blow up or the transmission to go cause it is on it's way so!!! But again sorry about the book Matt !! U guys stay safe!

Cool

Is their a website or address where I can send my computer for repair thank you for the info

How do I know which ECU I need if my speed density car has been converted to a maf

I'M HOPING MATT STILL REPAIRS COMPUTERS CUZ MY A9L CRAPPED OUT!!! I just had this problem that Matt was explaining in the beginning about the fuel pump running on also didn't have a 5 volt reference no TPS reference or anything like that or diagnostic connector power etc... I remember watching this video a long time ago but I didn't remember exactly the beginning of it where he explained exactly what was wrong with my car SMH I needed a new fuel pump anyways so I replaced it and then inspected the computer 2 different times and finally noticed that one of my capacitors was literally just pouring out look like oil or something from the bottom of it onto the ECM board tried replacing that capacitor and the other 2 but didn't have any luck I think I might have burnt a Trace...

I have a issue with not getting power to the switch wire on the fuel pump relay the green w/ yellow wire. Could it still be my computer? I've replaced the relay the eec relay the ignition control module and jumped the fuel pump relay and got pump to come on with the car still not starting at 50lbs of pressure on the gas line.

What’s you address so I can send my ecm to you to fix

I have a Rotunda 007-0047. I am looking for a picture or scanned copy of No. 26. That's the overlay Matt is using with the machine. It would be a tremendous help to the Foxbody community if we were to get a scanned copy. Please help!

Wish I knew this a couple of Months ago I spent 500 on a computer

I want to ship my computer. How would I pay for it to be done? Will they send me a link in my email to pay?

😳😳😱😱

what a phone # for this shop

I would like to put in a comment about the work from this guy I sent my computer to him in 2021 just before he had his last show in Charlotte hey call me to let me know he received the computer that he checked the computer out and the computer was fine I ask Matt if he could change those three computer components I don't know the exact name for those but over time they start leaking and when they do if not caught in time it will eat up your board I do mine were okay cuz I had checked them but I wanted them changed anyway he said he could do that no problem I finally get the computer back and the computer is wrapped in white paper and it says warranty voted if opened well I need to get in there to put my SCT chip back in so I open up where I can put the chip in took my flashlight looked up inside I can see he changed those things for me then I looked underneath and I saw a wire so that made me open up the computer he had taken small wire and soldered it to different points on the back side of the computer which I have no idea why he did that but I knew I could not run my chip in the computer the way he had it set up so I put the computer in the car started it it ran like shit it fouled out my plugs every cylinder was loaded with gas I was having a problem with the car that was the reason why I sent it to him so I took the computer to a friend's house put it in his Mustang which I do ran very well the car started and loaded up with raw fuel he cut the car off and said your computer is no good put his back in fired right up I urge you not to send your computer to this guy he never called and asked me if I was running a chip in the computer he never told me he was going to do what he did to the computer I just spent $600 for another computer and had to drive 200 miles to get it I will never deal with this guy again
