- Having no start problems with your Honda vehicle ? Well on this video I show how to repair the main relay assembly on a 1990 Honda Accord with 2.2 engine, many Honda models have main relays that go bad from time to time and can be repaired from little to no money at all. The main relays are common problems with Honda's especially with the mitsuba type relays which are OEM, The solder used in these relays tend to crack and cut off the connection needed for the fuel pump or ecu/ecm to function. A soldering iron is all that is needed but if you can't get your hands on one you could always heat up a screw driver to reflow the solder to make a good connection and correct the problem.
Before throwing tons of money into fuel pumps or other parts, check the main relay first.
Thanks for watching and subscribe especially if this video helped you out.
Hello All and thanks Ray for the guide on this repair. I followed the instructions and was successful in starting my vehicle again. I did run into an issue though..........
In an effort to fit the fuel relay back into it's plastic housing underneath the steering wheel, I inadvertently brushed the solder joints up against the metal adjacent to the it. This in turn caused a small/brief flash of sparks on the relay. i fitted the relay safely back in the housing and was surprised power was running to the unit at all with the key out of the ignition. I examined the relay and did not spot any damages from this incident.
So now here is my issue:
1. vehicle will not start (not surprising)
2. I have examined the driver side fuses and fuses under the hood (passenger side) and none show to be blown.
Where might the short be and how should i repair it?
Is there a fuse in another location I should check?
Is the best place to check for short circuits the brown harness/clip?
Any recommendations would be extremely appreciated.
Thank you
Sounds like the relay might be shot after shorting it out, at this point you might need a new relay. Hopefully, you have solved the problem since you posted your comment?
RaysFabShop hey thank you for your reply! I did swap out the fuel relay but came to find out that the sudden short burned out my ACG(or agc perhaps) fuse under the hood. I replaced that 15 a fuse and things started right up. dodged a bullet :-)
You really got lucky on that one, I will be pinning your comment so others can see it and won't make the same mistake.
Next time, don't plug the relay into the wiring harness while maneuvering it into its mounting position. Plug it in after it has been secured and the chances of shorting something out are essentially zero.
"was running to the unit at all with the key out of the ignition." Terminal #1 of the Relay is fed by power from the battery by way of the underhood fuse box.
Thanks a lot, the world needs more people like you. DIY is the future.
Thanks for checking out the video, the car is still running after repairing the relay, but one day I will buy a new one for it.
Amazing! Thank you for this. My 1991 Accord (100k miles) would not start recently. Checked the fuses and all are ok. Replaced; starter, alternator (and drive belt), distributor cap, wires, plugs, and even the battery. It drove well for 3 days then died AFTER ALL OF THOSE NEW PARTS! Will be changing the relay. Thanks again for the informative video! I also used solder to fix the power door locks relay. Looks like this is the same exact procedure.
I am glad it worked out for you, I have to resolder some other components on my Honda, I have never seen any other car company have solder failures like Honda.
Found this plus the comments and I fixed my 94 Honda Accord from not cranking in the heat with a simple solder of Fuel Pump Relay Switch, easy and cheap to fix over all the alternatives. Thank you and I hope you all have a blessed day or night peace ✌️🦉🖖
Best video yet covering this problem! Thank you very much for taking the time to post this!
1992 Accord relay test:
Battery positive to #6 terminal. Negative to #8. Check continuity (continuous) between 5 &7. If good, do next check; otherwise replace/fix relay.
Positive to 5, negative to 2. Light between 1&3. If good, do next check; otherwise replace/fix relay.
Positive 3, negative 8. Continuity light between #5 & #7. If good, relay is fine; otherwise replace/fix relay.
Use alligator clips on ends of two wires. Clip terminals using clips.
You also need continuity tester (has light).
Follow instructions above for the 91/92/maybe 90 too, Accord only. Maybe also 93,94 (not sure). If part number at AutoZone is same for all years, then should be okay to test.
This is my contribution to keeping accords alive.
Seeing how to rebuild these relays is really helpful. Thank you.
However, a word of caution about adding solder like this. The original solder appears to have a higher melting point than what was being added, which probably means that they are significantly different alloys (most likely the original is lead-silver while the new is lead-tin). Mixing them will produce yet another alloy, which is almost always more brittle than either original. In other words, I am skeptical of the long-term reliability of these new solder joints. This problem can be somewhat mitigated by either removing most of the original solder (with fluxed copper braid or a "solder sucker") before applying the new solder or carefully re-flowing just the original solder (use some flux if it's wetting surfaces poorly). That being said, the above mixture will obviously work way better than a joint that is already cracked. :)
After all these years the relay has been going well but you make some good points!
helpful. thx a lot. same info as many others...they all mostly said go ahead & add more solder to ea connection so u don't have to deal with it more than once.
Fixed mine yesterday worked like a charm.. now i need to know what fuse controls the break release that allows you to take car out of park. good vid!
kopfgeldjagar thanks but I do have break lights.
My 99 accord has a slightly different relay (Siemens VRM 00-22. I did like you said and so far so good. Thanks for the information.
Thanks Robert, mine hasn't given me any more problems and it's been years!
I tried it works, thanks bro
I love the mini torch poised just above the big red gas can at 11:55. I hope he doesn't have any fumes in the area!
Very helpful. My main is not clicking but there’s no broken soder
Thank you
did it .. its working .. thnaks !
Good Video !!! Although this wasn't my problem. I was trying to find the Left / Right Turn Relays on our Honda and came to your Video... So it inspired me to look into my Turn Relay. Although they are CHEAP, but it's good to play with them and see :).
Great job and very informative thanks bro.
The joints on the PGM-FI main relay circuit board assembly are rather large. Instead of using a small, sharp tip or filing the tip on the iron to a point, i would choose a 1/4-inch (6 mm) chisel tip to dump a lot of heat into the joint quickly, thus reducing chances of overheating the circuit board traces and the components.. If you have an industrial soldering station, choose a 700°F (370°C) tip or set the soldering station to 700°F (370°C). Clean the tip by lightly wiping it on a wet sponge before proceeding and use Sn63 eutectic rosin core solder, the type that is used for electronics prototyping work. If you use lead-free solder, the iron temperature may need to be increased to about 800°F.
I'm going to attempt to do this myself hope it saves me from having to buy a new pump
I hope it works for you!
@@RaysFabShop it worked for me it was a bad relay the entire time thank you for posting this
@@thomasschell1344 Glad it worked out, Happy Thanksgiving!
Excellent vid bro! Kudos
Hello I am using your video to review the same relay and immediately noticed mine does not have the spring notes in your video. Can you tell me a little about that piece? Thank you in advance
My 94 honda starts when giiven gas.
has no fuel pump working
put in new pump and Nothing
Could this be my problem?
Im gonna just buy a new one from Auto Zone for 59.00
and pray !
I took the relay out, soldered ALL the points on the board, and placed it back but the car STILL does not start in the heat/after it rains until I cycle the power 3-4 times. What else could be the problem??? I had a brand new fuel pump installed along with a brand new distributor. 1996 Accord LX 2.2L Sedan.
Same problem with mine, how did you repair it?
@@ismaelvalle5720 I ended up retiring the car and purchased a new 2014 Civic. Still miss that car, 😢
El mío tenía el mismo problema, NO LLENABA LA FLAUTA DE GASOLINA, ya que no enviaba la señal. Es ese relej de doble función. Para repararlo hay que tener a la mano Cautín y estaño y avivar nuevamente los puntos de soldadura, ya que al pasar los años el estaño se enfría. A mi me funcionó, el mío es un HONDA CIVIC 1992.
I was wondering is that main relay in a 2003 civic ex 4door 1.7 in that same place?
You have gotten a pretty good deal them cars will keep on going if took care of nice repair
Thanks, The car needs tlc but in time it will be sold or used to touring.
Thanks for this, very useful info. I will attempt this before replacing.
Noticed your fuel gauge is reading even with the car off. Is this normal for these Accords (I'm fixing up an 88 Accord and have noticed the fuel gauge stays at a particular level even though the sender seems to be working)?
Always wipe your soldering iron tip with a damp sponge to keep it clean
Thank you so much! helped so much
om mau tanya kalau cetek" di bawah dashboard relay yang mana ya? terus tiba" suhu naik, apa relay blower ya?
yang 12 volt
Hi, in my car, a honda Civic now replaced a new fuel pump and got another AC pump relay, but unfortunately there is still nothing! I turn the key and do not click on the relay and the pump does not go but if you think of a car then it starts, there is a click and the pump goes. would not receive AC power from the relay ?? what should I look first of all?so if Ac is good relay,and the auto, ignition does not leave yet onto him I get it and nowhere nothing! check engine lamp secular one,but neither ac click,neither ac pump murmur no! security it's all right.
EXCELLENT..!!!
My civic 92 dont start. I will try make you done. Tanks from Brasil
I have a Honda Civic 1.4 GL (EC9) and this version doesn´t have ECU.
Does it have a Main Relay too?
Cause I already tried to find it and I can´t see it anywere.. :/
Came up!
I have a 2003 honda accord ex . 2.4
I was driving and all of a sudden the car stalled on me . I tried to crank it a few times and it started and cut back off in like 5 sec and after that it hasn't started yet. After I try to crank it there is a buzzing from the ignition until I turn it back to the 1 position. Also when I turn to the 2 position the "D" gear indication comes on for a few seconds and then goes off. Any suggestions would be greatly appreciated . I changed the ignition switch but that did not help.
Oh is that all 159000 Honda Honda go go go
Looks the same as the one in my 2000 accord
Good job!
You can also test the relay and the harness. Justanswer dot com has a main relay test that was done for a 1991 Accord. Somebody else already paid for the information, though you can read the responses.
Do a search engine search for : justanswer 1991 Honda Accord DX main relay
Civic probably has different checks than Accord, since I think the relay has different pins numbers in different locations.
But you can check the relay before and after soldering using the test sequence provided by justanswer.
Also, eBay may sell junk relays (bad relays maybe found in dumpster at factory), so probably best to go to AutoZone and buy a new one (lifetime warranty too), the price is three times as much as eBay.
My 90 CRX has been nothing but trouble. One thing after another.
Cuál es la falla del Main relay y cuando empieza fallar te marca en el tablero alguna luz que te indique que está fallando cómo darme cuenta que es el may relay
Add your own solder to the old and the old will puddle with ease
Azt a műveletet, amit ebben a videóban láttam, nálunk nem forrasztásnak hívják, hanem "taknyolásnak".
Man these honda relays are cheap I rather buy a new one then take that chance with a 20 plus year old relay
TheBeautifulme1985 I agree but sometimes you have no cash and you have no other choice but to repair, I know if I were rich I would probably just buy everything and not fix anything.
there are two types of men in this world. those that will rather try and fail and then there are those that rely on men that try and fail. and you my friend are the latter
Local parts store just quoted me $100 for it. $40 At rock auto. Not cheap for a RELAY!
I have a 2000 honda accord when i turn my key it does all that but sometimes it doesnt want to start i have to wait 30 minutes and it starts again its really pissing me off
you can email me at crowder834@gmail.com i dont stay on youtube prob wont get ur reply to be honest
Hasta se me olvido el porqué estaba viendo este video ja ja
Ok so i get what you are doing here but once you make the solder re flow that's it always solder on the level and get in and out as fast as you can. No need to be in there with all that heat farting around one pin like that. Just saying...
-genial-
Old Honda owners, tell your story.they are fun to drive but they need fixing all the time,we all need it so show it. Or buy a new car?
My car always needed fixing until I took the engine out and rebuilt it then replacing just about every component and has been giving me over a year of trouble free service. Still cheaper than a new car.

Just repaired my 95 odyssey.
Replaced the fuel pump fuse and cleaned the relay as there was slight rust around 2 solder points.
I also have an ant infestation which I'm trying to clear now.
--The amount of kars that have this issue is probably HUGE... or rather, peeps having problems with their vehicle & pay someone to fix it.. due to the relay. That said, so much shxt kan stop your vip from starting.
Ya M111
Who has time for this..new own ones only $75
This is free...

RaysFabShop 😂😂good one
It was good Ray you did good on this video. My big problem with the 1990 Accord is people trying to steal it. Two Clubs brake clubs
Ordered wheel claw/boot. Trying to rig a way to lock down hood.
Ya solo tienes la mitad del carro...por eso te falla ja ja ja
20 minute video to do a 2 minute fix.. Really quick fix needs a really quick video ffs!

How did you solve this.
