THANK YOU FOR WATCHING!
2:00 am. On my way home from work. Stop at a 7-11 to get a drike came out car did not start. I went crazy for a bit trying to figure out why my car won't start. Call a tow truck company they wanted $350. Ok so I find this video and is the exact issue I'm having. Sat in my car watched from beginning to end. Swap out the fuses just like on this video car started right up. 45 MINUTES LATER. THANK YOU A MILLION TIMES. NEW SUBSCRIBER.

You are going to be in the top automotive diagnosis specialist on you tube, I need to learn to make videos because I have a lot of experience to share also
Thanks man! I really appreciate it. I look forward to seeing your videos.
I had this exact problem ( today 7/1/2020 ) with my 2005 Mustang V6, with very intermittent stalling. I used to be an Electronics Technician, so I heated up the PCM diode with a hand held hair dryer while the mustang was idling and the mustang stalled. I measured the diode and it was open (bad) until it cooled and tested normal. Thanks so much for the video.
Where do you buy the diode?
@@cameronciampichini9 Local FORD dealer, Ford part # is 4F2Z 14A604 AA, also there is an other diode just like it in the same area maybe a few rows over that you can swap and see if this is your problem.
What the diode supposed to read thanks
4f2z 14a604 Aa is that the same part number for the gt ?? I checked and it said it won't fit?
@@Jfizzle813 Looking at pictures of the 2005 GT fuse box, it doesn't look a lot different than a regular Mustang fuse box.I can see the writing on the diode (1.0 ). in the pictures. Amazon said it would not fit my vehicle lol. I would put the part # in Google image search and see it it looks like the one in your car.
Thank you after 2 months of "experts" changing numerous parts, including changing fuses, relays and diode I rewatched your video last night and came to the conclusion I had a faulty fuse box, swapped it today and all the codes are gone and no more throttle body chatter. This was on a '06 Supercharged Saleen
Awesome! I’m glad I could help. I love Saleen Mustangs!
@@robertknott7697 Hi Robert my Saleen has done just over 20,000 fast miles
Basically it come as a last resort, I am an older Ford mechanic with limited electronic experience. Had 2 different tuning guys look at the car with no actual results.
My Saleen is heavily modified with all mechanical work done by myself with exception of tuning.
After watching this video it gave me more insight into the fuse box. So I decided to remove the fuse box from one of my other Saleens and change it over and it rectified the issue. I pulled the fuse box to pieces and traced the problem inside the fuse box
Make sure all your earths are clean and secure
You seem like a great mechanic. Good job!
I was taught to always check fuses and relays first, is one of the least expensive things to rule out.
Thanks for posting.
Thanks for watching!
Thank you so much for this video. We have had an ongoing problem with this for the last 6 years since I rebuilt the motor. My wife races it and has not been able to since this intermittent problem! I replaced the diode with the one out of another fuse box I had and hopefully that works. I have checked so many things trying to trouble shoot this issue. I was about ready to burn the car to the ground lol.
I had even put that circuit tester in and had pulled the diode out a few times, but hadn't replaced those.
I hope this fixed the problem for you. Thanks for watching!
2006 V6 4.0 Mustang stalls when driving. like it completely shuts down. i have to put it in park and start it again AFTER wiggling the battery cables (i thought that was the problem) then i noticed it wouldn’t start until the mileage stayed on the dash. because at first it would appear and stay there but overtime, it would flash and all i could see were dashes - - - - like so… the car wouldn’t start until it stayed. no cooling, it wouldn’t start for hours/days. so i found this video and replaced the fuses! cost me about 17$ EASY fix! after being told i needed a new ignition, battery, starter, crankshaft sensor and all kinds of things. this video was very helpful so if you’re having the same problem as me or the video, TRY REPLACING THE NECESSARY FUSES! thanks for the video
I just trouble shoot this today on mine It took me 4 hours and I never figuered out what happen I thought it was the security system but I did switch the diodes so that was what fixed the issue wow thank you so much for posting
Holy shit I wish I would have found this sooner! Thank you so much. I just did and so far so good! Question, we’re the gauges dead when this happened on your car?
Well done. It takes equipment for info and someone like you that knows how to use it. Keep up the good work.
this had a lot of good information. By replacing the DIODE the code b1353 went away?
Ohmygod. My 2008 is doing this exact same thing!!! Just left the shop and I didn’t have it a day before it did it again.
It seems the PCM power diode is there to act as a directional fuse, protecting the power relay and PCM. I suppose it will blow if the PCM relay gets reverse voltage like you might see from boosting backwards or if the alternator is failing with too much ripple. Strange that the computer was working but unable to communicate properly, and confusing that codes were not very specific. Worth remembering!
Fantastic diagnosis my favourite RUclips channel.
Thank you so much you helped so much. Keep up the good work.
What is the deal with American made cars, Ford, GM, Jeep, Chevrolet? They seem to have problems that bubble up big time after 5-8 years.
Eric 2007 same exact issue, will let you know if I can fix it . Your awesome for doing this man !
did it work?
Good video thank you. My right side running lights won’t work. I ordered a used sjb for it. All new bulbs and good connects. Crossing my fingers that’s the part will fix it
Great video, i got the car started but I still have some other issues. I think the diode did help. I still need to check those grounds.
Awesome! I hope this video helped.
This video keeps helping 2021💪🏻, do u mind giving the number of the fuse is it 35?
53
Ok that was awesome fix
However I do have a question?
How did the customer drive it for weeks with no problem before it did it again🤔.
Cause to me it sounds like the tips of the diode where bad losing connection.
So why would the diode go bad. Is that something that normally goes out, or was it just a random "end of life" situation that sometimes just happens. Unlike a fuse where you would want to find the cause of a fuse blowing.
Thank you broooo all I did was pull the 1.0 fuse out and it turn over after that I put it back in she fire right up thank you
Great video, smart and to the point! I have a very similar problem, I really hope this fixes it. Could jump-starting the car fry the diode? The PCM had issues, then battery died, jump-started and then all these new problems just like you described here started.
Hi I was just watching this video . My mustang gt 4.6 has the very same issue. And did the same thing you did. But when I put in the relay it only makes the clinking sound 3 times and the car won't start..maybe you can give me a bit of advice.
Check the starter
Were you able to diagnose the issue?
Great info, keep on making videos
Hello!
I liked and subscribed because your video was very good and informative. I have one question regarding the ECU ground. Where is it?
The car is a 2005 GT 4.6 3 valve.
Thanks in advance!
Found the ground location that you were looking for?
Great stuff!!!! Thank you for posting, awesome!!!!
wish i found this video a week ago! i searched for hours and didn't find a single thing on this problem! just spent 500 dollars on this repair lol
You saved my life bro god damn
Worked!!!!!!!
Thank you!!!!!!!
Excellent video friend, I have exactly the same fault, I already checked that diode and the relay of the pcm and it's fine, I even hear the throttle body as it activates, but it still does not start. Check in the passenger fuse box and everything is OK, what do you think it is? damaged pcm? Thank you very much for your support!
Did you get this to work ? I have the same problem. Right now
@@TheTeddykiller510 How about your issue, did you resolve it? and how?
I had the same problem come to find out the previous owner had the wrong size starter relay in the fuse box. Check all your fuses it’s crazy what you find
Fantastic trace. Nice work.
Was the check engine light illuminated prior to this problem to warn of a problem?
I have a 2018 Mustang Ecoboost that’s doing exactly what this one is doing. Taking it in tomorrow.
Thank you for your service!
Thank you for watching!
Great video!!
Love this video. You must be on decaf ? A lot LESS talking ! Lol much better and less annoying 😌
We have the same problem with an 06 mustang. Can you please show where/how you installed the PCM power diode. It doesn't look like anything else in the fuse box.
Is there a reason the check engine light is still on at the end? My car has been at the ford dealership for almost 4 weeks now and they don’t know what they’re doing
Perfect execution
Thank u so much I did it to my mustang ang it worked I need to find out how to put it in order
Awesome video! I got an 05 V6 with P0403 code. Trying to fig out since EGR "looks" new, which action to take next? I can't find diagram of PCM for this anywhere. Also looking for voltage coming out of harness to EGR. Thanks for any help
I love ya dawg! Saved me money I removed the rear window defroster relay and placed it in PCM relay and it worked on my 2010!
where do you get the fuse?
Props to you....just saved me a shop bill!
Glad I could help!
I'm dealing with this shiz now. I got the transmission replaced and they didn't reconnect the engine block ground. It had the no start you describe off and on for a while then it finally wouldn't start at all. I discovered the ground and reconnected it and it ran for two days. Now it won't start again. It clicks in the cab but no starter action. I can use a copper wire to bypass the ecu and jump the starter to the positive battery terminal with the key in the run position and it will fire right up.
did it work? having the same prob
@@jaybenz3838 yes. unfortunately the ignition switch had to be replaced shortly after. but it cranked right up and ran as soon as I reconnected the ground on the back of the block. the bolt was gone so I had to get another one from a hardware store.
I also cleared the codes after I reconnected the ground.
@@jaybenz3838 sorry. I realized after commenting that this was not the video that led to my resolution. The next problem mentioned above ended up being the ignition switch.
Yo my guy my mustang 06, decided to die mid drive. I noticed my steering wheel getting stiff and I knew my car was going to die. Engine died, but all my lights stilled worked. I put it in parking and started up again and turned on like nothing. As I kept driving it the engine wanted to die again, but it didn’t and managed to get home with no issues. I started up again and the car started up like nothing.
Sounds like a bad fuel pump
Dude thank you so much
Glad I could help
I'm having this exact problem. No communication to pcm. I don't see a ac compressor diode to switch around anywhere . Mine is an 09 gt
Very good señor. Regards mate.
Well done.
Thank you man
Mine is similar but on the relay Bottom L 8.59v top left 10.26v top right battery voltage 11.6+ bottom right ground. Diode works and did the swap...got P0685 code some wires not connected on c110 connector which is inline to c175b plug to pcm...issue starts and dies..also have p2104 and p2111
Any thoughts?
I have a similar issue, but when my car does turn off on me the starter still works it just won't turn on. I recently replaced the fuel rail sensor because it was turning off on me and that code came up however now there is no code and it is still turning off just not as frecuently. A quick fix that I have done is to disconnect the battery clean off the corrosion and it turns on again, I do notice that it acts weird when I turn on the AC. Totally confused here.
I have a mustang 06, i had it for about a month and every morning that I go for a ride it won't start, just cranks. Took it to a mechanic, and was advised that it was a bad fuel pump, replaced it and the next morning it did the same thing. Any suggestions?
I have a 05 gt v8 4.6 that keeps blowing fuse 42 and 54. Any suggestions. Thanks
Hey man hope you can reply but my mustang cranks but the fuel injectors aren’t getting ground, any ideas on what to do?
Hey man I’m really enjoy what you did with this car ! Thank you
But I have question here
I have the same problem with 2010 Mustang 4.0
And the mechanic told me I have to change PCM and I’m not sure about that I would like to know where you work so I can bring my car to you what you think?
I'm located in Houston, TX. Thanks for watching!
Did you fixed your problem? I also have a 2010 mustang 4.0 which is giving troubles. Intermittent stalling, sometimes runs perfect but sometimes it would feel slow and acceleration would decrease , and the check engine light just won't go away even after replacing the sensors or egr valve which were the codes that it was displaying. After resenting it will come back with the same codes. It would idle poorly and misfire. I have it checked fuel and electric system and the mechanic also told me that it may be the pcm/ecu. And wanted to know if you fixed it by replacing it.
Abel Delgado hey 👋 yes I did I change the computer and everything is fine with car now running good and never stalls again
@@heshamismail6782 you went to dealership or you bought it somewhere else?.
Also how was it? The programming and key reset and everything.?
Have a 2007 mustang that the battery was changed and the polarity was wrong in other words hooked up the battery backward now there is no lights or instruments working inside the car. Any idea what is wrong. Checked all fuses all good.
Probably a dumb question but could I test the connections with a multimeter I don’t have a touch wand
We change fuel pump it start but won't stay running .we change alitnator .do u think it's my pcm power relay.dealership want to fix my issue over 900hun .I took my ride back .still we start but won't stay running
Try cleaning your grounds bro wasted tons of money on my car because it was throwing codes left and right
Great video! Thanks
Hello, does this diode also fit for a 2006 Base V6 convertible? I live in Austria and have problems to fix this. The Problems with this was since 1 Year nobody can find the problem, so this is my only chance.
On my 06 mustang it has the same problem but only has it when it is cold outside. When it is 60 degrees an higher outside i don't have any problems with it. An i can't find a cpm for it anywhere.
Thanks again.
My car was running then one day it just didn't start back I put plugs new wires I made the fire order was good and got spark but won't start I check for code it say no fault codes can you please help me sir
I have 2006 mustang gt 4.6 reading aat -7 on scanner but circuit is good. Replace everything but still doesn’t start, unplug map sensor and runs but run rich. Any ideas
Just imagine trying to figure that out without a schematic!
Ok so my mustang died while i was driving it, The key wont turn, my kilometers go blank and the Throttle body is making the same noise when i *put in the pcm fuse* not take out. Could this be something completely different?
I clear the codes with an OBD2 reader and it turns, it actually started once, but after that it locks the ignition and its the same process again.
ADD people died at the point where the music kicked in. I had to watch that shit five times. 🤣
Sorry about the music. My mechanics didn't like me turning it down lol! Thanks for watching!
@@ADVANCEDLEVELAUTO it's all good man. I was just amused by how many times I had to watch it. 🤣
I have the same problem, I did the same thing you did but it didn't work, the problem persists, the same message continues on the dashboard and the car still won't start, any idea what else I could check?
What's the status now? what did it turn out to be?
Where are you located? I have the same problem in my mustang gt 08 i would like you to take care of ir
Do you have a a video or any advice on 2005 Ford Mustang 4.0 automatic the car drives when you're driving is bogging down cut in and out in and out and then finally catches and drives replaced injectors fuel pumps oxygen sensors spark plugs the list goes on and on but it still cuts out like like it's catching air or clogged up injectors but I literally just replaced them a couple weeks ago I don't know I need help
There are many possibilities. Could be Throttle body or mass air flow sensor or clogged catalytic converter. I wish I could do more to help, but unless your in Houston Texas there isnt much I could do without testing the car myself. Thanks for watching!
@@ADVANCEDLEVELAUTO hey, where is your shop or phone number to your shop?
@@ADVANCEDLEVELAUTO same problem here and I would like to bring my car in
good video
So what caused the diode to go bad?
That diode can taste with a multimeter ?
GREAT!!
I have a 05 that willnot start when the switch nothing no inside light no nothing
Hey if this does bad does it give miss fire ?
Hey man. I have a question. I have a 2010 mustang 4.0 which started acting like crazy sometimes it would run perfect and sometimes no so much. The check engine light always keep on coming back after replacing the bad sensors that I got in the codes but everything that says is bad it's been already replaced. So an auto electric mechanic did the same as you did.. He did a diagnosis of the whole car wiring and found out that the codes. Im getting are all connected to pcm. Which are. All 4 oxygen sensors, so he took the pcm out and saw there was a lot of humidity so he cleaned as he can but told me that that may be the reason why I had a defective pcm. After he did that. He reset it and everything and the car was running perfect again for two days but then the check engine came back with the same codes and now I'm pretty sure is the pcm that is bad. But the dealer is charging me $2300 for the whole job including the pcm and the labor. They are saying that takes up to 4 hour of labor.and honestly I don't have that kind of money right now. I just wanted to know what are the steps or posible risks of installing myself? I know that I will have to get my key reprogrammed after but is there something else that I have to be careful about?
removing the pcm and installing another is no big deal.
the pcm has to get programmed and the pats system.( anti-theft).need 2 keys to be program on some models..
@@guayaco-dm3vu I done it alredy. After replacing the pcm I had some one who programmed the keys again you were right I used two keys in order to do so. And all for $560 I bought a remanufactered pcm in flagship one website and took it to a mechanic who knows how to do that kind of programing and that was it. Codes gone. No ore stalling or any other problem.
@@Abeldlg
Glad to hear it.
You solve the problem?
@@Choforo350z Yes my issue was a Bad pcm or computer. The pcm received an insane amount of heat due to its location on the 4.0s v6 engine. So I remember I ordered one off from ebay from a company that sells reconditioned car computers and all my issues suddenly disappeared no more rough idling or no more stalling in the middle of an intersection. A car electrician did helped me a lot because of his diagnostic.
I have intermittent click but no starts on an 07 GT...I think its the PATS system being that when I key my door it usually starts with no issue..Can this be an electric issue as simple as what you fixed?
@ sidenseen1, did u find out what the problem was? I have a no crank no start problem as well switched the diodes around but still no start. Turning the key won't even crank but if I jump the starter relay it will crank. Also opened up my fuse box and under it I can see that there is a burnt wire that turned out to be the low speed fan.wondering if that burnt wire is my issue ?
Hey man do you have a number on your shop or your cell have a major problem no one can figure it out
Will it fix it if the key switch is taken out
Can I have your shop information? I’m habing the same problem with my mustang.
Just wondering, since a diode is like a check valve, allowing current flow in only one direction, could it be possible to install it backwards,therefore blocking the voltage supply to the relay?
Did you ever get an answer on that?
@@janedoe43 no sorry. No answers.
No, you can't put it backwards because it has a one way finger on the fuse
Do you live in San Antonio
How can I find out if my pcm is bad. It throws 3 o2sensor codes and a lean code and a pedal sensor. I replaced all o2 sensors and still codes. Car losses power and idles low at stops, also the car does rough starts.
👀 did you figure it out?
La musica in da back tho 🔥
I need help, my mustang 2006 v6 doesnt start, it cranks but doesn't start. I have replace the fuel pump nd is still doing the same thing, i check the inertia button and same thing i check relay and fuze and nothing. Any help idea?
Did you figure out what’s wrong ? I have an 07 throwing up no codes sometimes starts sometimes will only crank and just starting stalling while i was driving
How about starter and the battery
So I'm having the same problem on my mustang I did exactly what you did yet it still didn't turn on what should I do
Clean the ground cable contact
Got the diode, replaced it , still nothing damnit guess it's going to a mechanic 😢
My car did the same thing I did this process it cranked but it blew can my pcm be bad or short ?
cris reyes hey just curious did you ever find the problem my mustang does the same thing
My pcm relay keeps popping and making go into limp mode
If this fixes my car I swear to God I'm going to buy some merch. 😆
I hope it works. I've found that it's pretty common for the pcm diode or the pcm relay to fail on Fords.
How do I clear the theft light
