mine was arced all over, and i cleaned it up and just re soldered the cracks and then i just reworked all of them and it worked perfectly afterwards !!!!!!!
Did this yesterday…my car was doing the exact same thing - mine seemed to happen on really hot humid days - I live in Southeastern US now, but it didn’t do it when I was living in AZ the last 2 years (I.e. it’s more dry there)…I just bought the part on eBay for $23.22 shipped and it came with the gray box so I didn’t have to finangle it out of that gray housing. If anyone else buys the part online as I did, all you’ll have to do is push the whole unit up towards the ceiling to slide it off the metal piece, unhook wires, and switch them out. It will prevent you from having to go to the junk yard and might make the job slightly easier. But I spent $21.22 cents more than legendary PB Man 😂 ..thanks for the video man!
One thing I'd like to point out about this video is that the relay for a 90-93 Accord is the same as the relay for a 94-97 Accord. So I would imagine that the relay from the 02 Accord should also work for a 90-93 Accord as well.
1995 Honda Accord EX...I replaced the relay, and the fuel pump, no good.... The problem was the ECU or ECM. I bought it at Rockauto and it fixed my erratic fuel pump issues right away. Thank God the nightmare is over. easy fix. Learn how to replace the ECU/ECM on youtube, do a search.
Thanks. I have a 1995 Honda Accord EX. Cranks, fires and dies. When it starts, it sputters to life. Sometimes runs fine, but now seems to be getting worse. I'm going to check this. Computer threw a 09 code which is supposed to require a new distributor according to a Honda mechanic friend. Replaced the distributor. No difference.
@Peanutbutter Man, I did this and still did not hear the fuel pump but when I jumped the plug the fuel pump come on and stay on, do you have any suggestions?
no check engine light.. my symptom was no start when interior of car was hot.. the soldered joints on the relay expand a little when heated and that can expose cracks in the solder.. which can lead to no start.. with mine, when then interior cooled off my car started and ran fine.. check out this video.. main relay issue starts around 5.25.. th-cam.com/video/6CMZ4g8n0FQ/w-d-xo.html
I have this same problem with my 94 civic. I took the main relay out of my 98 civic and it still won't kick the fuel pump on. But I have learned that if you take a jumper wire to #5 and #7 hole in the connector the pump will engage, but it will be constantly engaged.
why woukd it start if i sat for a while and eventually heard the click. I knkw it's my main relay as I held it in my hand tbis morning while i was waiting for it to engage and felt it engage in my hand.
I think it is related to the temp, hot and expanding the gap make it disconnected. When it cooled down, it connected again. Usually I cannot restart my car again when the engine is hot.
No. I did not have any problem with gear shift lever locking.. If that's what yours is doing you may have an issue with your ECU (engine control unit) or TCU (transmission control unit).. Both are located under carpet on the passenger side floorboard.. At least that's where they are on my 95 Accord.. A faulty ECU can also cause intermittent no start condition when interior of car is hot.. Soldered joints on the ECU can fail as they heat up and expand exposing cracks in the solder.. Just like on a faulty main relay switch..
I have a question. I took the Main relay from my Honda accord 1998. and the box say this: relay rz-0158. I found an exactly piece online but with different number: rz-0159. Do you think this will matter? You think this will work?
My 95 Accord does not have the green key light so I can't help you from my experience.. However, the link below will take you to similar issue with a 2000 Honda Odyssey.. No start, no green key light.. They replaced the main relay which fixed the problem.. www.odyclub.com/threads/2000-odyssey-green-key-light-not-coming-on-problem-solved.312177/
this is make work . just resolder the existing one . the one from the junk yard shud be resoldered any way cause it's used even if it works . at this point you'll have a spare. it duzent look lyk itll fit anyway .
I have a 2001 civic same thing as 02 03 04 05 there are no main relay anywhere except 2 blue relays on the passenger side below the dasboard (fuel pump relay) the main relay are not equal 5th, 6th generation to 7th generation. Below 2000 relay doesnt match in any part store online ebay autozone google etc. my question is where is the main relay located in a civic 2001-2005???? THIS VIDEO DOESNT NOT MATCH any part store...
@@tongo117 thank goodness! My Honda Accord started doing like your video a few months back, I'd start it in evening or cloudy weather & it would start. Then, afew weeks later, it started all the time which was great! However, about 2 weeks ago, I pulled into driveway, was gone for ten minutes & car would not start at all, no turn over, no 'almost' starting but nothing, just a few click sounds. Neighbor tried to jump battery but nothing, battery pretty new. But yet, my lights, would come on, windows worked, turn signal, most of the times I've tried anyway. I'm desperate for help. I'm 55 years old, alone & lost my job cuz of car, now I have to walk to a crap job & I'm disabled! Obviously, I have no money for tow, dealership or garage at this point. Thanks to your video, I'm pretty sure it started with a bad main relay switch but now, it almost seems like something got disconnected or idk, it happened from one minute to another! I don't know where else to turn &trust me, I've asked around for a mechanic to look at my Honda and diagnos it but people are not reliable! It proves I have no one to help as I'm contacting you in GA, I'm in Southeastern Virginia! ! Sad hey? Just a really bad time right now. Any ideas sir?? Could the main relay finally have broke? By the way, when I price those, it's from $14 to $70+, so I don't know why that is? Thanks so much for replying! !
@@ericramming thank you for your input, I really appreciate it! Believe it or not, I'm STILL working on the darn thing!! It's become an obsession! LOL!
I know this post was a few years ago, but I’m having the same issue with my ‘96 Accord EX, random no crank, no start. Made a short video on how I get it to start, takes me about 15-20 seconds to start it, after getting it to start trouble goes away for some time until it randomly shows up again, it doesn’t matter what weather or temperature. Haven’t gotten a chance to troubleshoot it yet. Here’s a link to how I get it to start. th-cam.com/video/bMJ8eT7x2nw/w-d-xo.html
been having the same issue for the past year. randomly wont start with same strong cranking. its like a luck of the draw to make it start. sometimes leaving it be for one hour then coming back. would start like nothing happened. wierd. replaced my spark plug wires cause i saw the contacts was rusted. didnt help
mine was arced all over, and i cleaned it up and just re soldered the cracks and then i just reworked all of them and it worked perfectly afterwards !!!!!!!
Prelude's also have this issue. All you have to do is resolder the connections and you're good to go!

Awesome repair video.

@@johnlibonati7807 my goodness. not even the mechanics can fix it in one try
@@kickboxer8173 mine was the ecu. Bought one on ebay for $80. Ran like new after I plugged it in.
I hope this is the fix for the car I got
@Peanutbutter Man, I did this and still did not hear the fuel pump but when I jumped the plug the fuel pump come on and stay on, do you have any suggestions?
What is the usual symptom of having a
bad main relay aside from having no start?... Is the check engine light lit?...
no check engine light.. my symptom was no start when interior of car was hot.. the soldered joints on the relay expand a little when heated and that can expose cracks in the solder.. which can lead to no start.. with mine, when then interior cooled off my car started and ran fine.. check out this video.. main relay issue starts around 5.25.. th-cam.com/video/6CMZ4g8n0FQ/w-d-xo.html

I jump start that high which wire do I use ain't it the two top four you have to put them two and
why woukd it start if i sat for a while and eventually heard the click. I knkw it's my main relay as I held it in my hand tbis morning while i was waiting for it to engage and felt it engage in my hand.

do you encounter any problems with the gear shift locking while you are doing this?
No. I did not have any problem with gear shift lever locking.. If that's what yours is doing you may have an issue with your ECU (engine control unit) or TCU (transmission control unit).. Both are located under carpet on the passenger side floorboard.. At least that's where they are on my 95 Accord..

lots of rz 0158's out there:www.ebay.com/sch/i.html?_nkw=rz%200158
Anyone know what else OTHER THAN the main relay, bad fuse, or FP? Would cause same thing??
Edit: (no power to FP)
bad computer?? th-cam.com/video/MUKbdrdVMyA/w-d-xo.html
Should I unhook the battery before I swap this out?
I never have but it would probably be safer that way.. Not safer injury wise but safer from the possibility of shorting something out..
@@tongo117 Thanks! You the man!
I'm having g a crank no start with my 2001 honda accord. Would a faulty main relay causes the green key light not to come on also?
My 95 Accord does not have the green key light so I can't help you from my experience.. However, the link below will take you to similar issue with a 2000 Honda Odyssey..

Green key light is immobilizer? Could be on due to relay
You could also just re-solder it for like 50 cents. Have done it twice
will this relay have the same probblem on the the new honda accord let me no thank
smart man
What about a part number??
this is make work . just resolder the existing one . the one from the junk yard shud be resoldered any way cause it's used even if it works . at this point you'll have a spare. it duzent look lyk itll fit anyway .
same problem here my 2001 civic does not start.
