FIXED! HONDA ACCORD FLASHING D4, Wont' Start, Won't Shift Solution Main Relay 

Thank you sooooooo much for this video! This fixed my issue. I bought the part for $12 on Amazon. You saved me hundreds of dollars, since I know a mechanic would have replaced the fuel pump first and it wouldn’t have been the solution. Seriously, you’re awesome for making and posting this video.

Thankyou so much for this upload! I replaced the relay rather than trying to repair it and so far it's working! I have 92 accord. This was extremely difficult to get to! I wanted to also mention that I couldn't tell if there were cracked solder joints so I just placed the new one in and it fired right up! Thankyou again so much this fixed my car. Been dealing with my car not starting on hot days for about a year now!

Well done video - I appreciate your patience and step-by-step instructions. I have a 1990 Accord, and they must have relocated the main relay. Mine is in one of the most inaccessible places I can imagine - still under the dash, but also under everything else including the fusion reactor and the main warp drive. This part seems to be an area of frequent failure; I'm glad they made it easier to get to. Thanks for the video!

Man thats awesome, way to go! I love taking old broken junk and making it run again. Information is the key, thanks a bunch. Really helped me out on my moms 94 honda.

You are the best omw to work at wouldn't start after getting gas. Same issue SAME SOLDER JOINT!!! I owe you one!!!!

Thanks dude I just fixed my car watching your video awesome video

Thanks for the video. Work great on my 94 Honda Accord . I found that one of the connections on the board was crazed so I reheated all of the contacts on the board. Car started up with easy . Thanks again

Worked for me on my 93 Accord! Thank you SO much!

Great video, brother! I love how you explained what tools etc. you used. The D4 on my 98 Accord is blinking but it starts just fine so I'm wondering if this would still help.

Thanks for your video it helped me get my car started.

Thanks for this tip! Your symptoms mimic mine almost exactly. Gonna bust out the soldering iron this weekend!

Nice! Thanks for the video 👍 I’ll give it a whirl on my 97 Accord. Last night, she was driving like champ after work. Today, getting ready for work, she did not want to start 😬 Had to take the old gas guzzler to work instead. I have Thanksgiving off and Friday so I’ll be troubleshooting the no start issue.

Works for me, thank you! (92' Integra with same problem)

This worked perfectly for my 93 accord LX sedan. Thank you!

Omg this could be the answer to my problems 😭😭😭 had 3 mechanics come look at my 97 acura Integra. Changed the speed sensor and nothing. Now someone said lock up solenoids but found this video by doing my own research.

Can this posably work for a 97 accord

You my friend are a god! Thank you❤🤘 you saved my 1992 honda accord f22a1. mint condition 113xxx

Same issue with mine where it won’t start and D4 and won’t turn over. Had to non op the car because I couldn’t find the problem. I’m going to try this as soon as I get home!

Haven't tried it yet but kinda got a good laugh outa this cause I've been working on cars for any years and I knew it was something simple. I got a 92 accord from a friend that was over it because (quote "the fuel pump went out" ) It was given toe I went there fired it rite up never had a issue however yesterday and today it's been over 100 degrees out and it all of a sudden wasn't starting and d4 was flashing so I Google it everyone's saying fuel pump I'm saying no way it ran great the whole time I've had it and bam I find this video. Will update tomorrow when I pull it out and fix it

Well done on the video, but my D4 on the Honda Accord is still blinking even though I replaced the main relay with a new one.

Very helpful thanks a million

Thank you sooo much. My new main relay came in today and I swapped it out. Tadaaaaa! Btw....Are your bones made of rubber? I only ask because I can't figure out for the life of me how you got under the dash. Lol Helpful tip for readers with the same issue, I used a mirror.

thank you, sir. good work. appreciate it.

Thanks a million I parked my honda for a whole year because of the same exact issue blinking d4 light and everything??. Starts sometimes and won't start other times.?? I am going to try 2 do this next I hope it works for me like it did for you.??

Thank you very helpful I have a 1993 Honda Accord that needs a few things done to it . Would appreciate any help you could give me on timing belt cover, belt and water pump Stay Well

Thank you for your vídeo Í had that problem in my Honda accord 96 so Í try to fix that problem thank you amigo

It's a well built car.

Hi bro thanks for the video 😊🙂 pls can you help me my honda accord si eclusive has no drive and reverse the S light ss blinking

My car HAD a D4 light flashing and then we lose power at times during the two weeks after a small fender bender I was in it still ran and then one day I was driving slow and I lost some power in the CD player shut off and came back on really quick and same thing with the rest of the power to the car and I saw a couple flashes come from under the hood which was crunched up a little bit from the accident. These could be pinched or expose wires, but then One night when I went to leave it started out as it always did just fine I put it in reverse and as soon as I push on the gas every single thing about the car shut off and has not come back on since even with a new battery in it. So I am wondering if it is the main relay or the main fuse. I want for these cars I don’t quite understand them inside and out I have definitely never had this problem with them, for this car only has 100,000 miles on it. I have it for sale on mine right now for dirt cheap and was informed today after several people told me it would be my alternator, That it could be one of those two issues of the relays or the fuse. If anybody who is in full of hot air good let me know because I was going to remove it and bring it down and have it tested for free at an automotive electric company as soon as I get back from fighting the forest fires. And it is only $60 for one of these parts. So if they only cost 60 damn dollars to say fix this car, instead of selling it for a 10th of what I bought it for, then I am going to frickinfix it. His name is Mr. Biggleswerth. Just kidding it’s name changes frequently from Piece of Shit, to Baby, Bedroom, Living Room, and Eyesore. But I’ll only buy Honda’s, Toyota, Lexus, or maybe Nissan. Eventually Ferrari(just one) or Hummer H1-BEFORE THEY RUINED IT for the Single debt-ridden Dads having mid-life crises and the TANF moms blocking two spots at the grocery store. Thanks for your vid man you may have potentially saved me from selling cluckin’ my car that might be repairable for $58.99, than accepting two hundred fifty regrets and likely receiving a simultaneous Thank you/FU note from the buyer advising me that he just bought a $2,000 car that cost $60 to fix and how lucky he feels.

I have the same problem with my 92 Honda Accord, the car starts with no problem, but soon as I put the car on drive, the D4 light keeps flashing constantly, woild it be the same problem?

If this helps, take a photo of the circuit board using the flash, this will(when you look at photo) show up all solder futs a cracks

Great job! Really appreciate your effort!

My 2002 accord just started doing this. Won't start and the D4 light will come on same time as it's in park. What should I do? I am desperate.

Where did you get that 10MM socket? I can’t ever find mine. 😂 Thanks for the vid gonna try this

It flashes d4 shiffs funny but after geting on the freeway it takes off a lil slow then caches up

This what mine doing

I have a 94 accord before u start it you see the D lights on and go away when start.i wont shift to 4speed

I noticed before the check engine light would stay on and the d4 light flashes immediately and it wont start. After you fixed The relay the check engine light goes off very quickly and it's running. I have a 95 accord but the d4 light will only start flashing after the check engine light stays on for 20 seconds. The fuel pump will not prime until that check engine light goes off. Theres no point in cranking on it because theres no fuel till the light goes out. This is my problem every morning. Once it runs for a short while I dont have a problem although its starting to take longer and longer for the check engine light to go off no matter what.

Good deal!

My 93 has D4 light on and won’t shift to second gear, any advice

What’s the part number of the relay?

I was going to say a magnifying glass googgle but I guess you already seen it.....

Bende 1996 Honda akord otomatik arabada d lambası yanıp yanıp sönüyor neden acaba

you should use flux on it it helps a whole lot

wondering how he determined that the main relay was the issue?

My D light is flashing, engine light on and car gets out of gear? Nobody can figure out wth is wrong with this car 🙄
