@rywire I got a Honda Civic ek b16a Vtec 1997 model Problem that I noticed is that when I turn my ignition on fuel pump prime all the time (non stop ) and car starts perfect my understanding is that the fuel pump need to go off with a click it doesn’t do that.i just need help with having the fuel pump go on and go off again once relay clicks
Tqsm for your great information really helpful till i recover back my honda down pass one weak.Finally i found constant supply for main relay drop to 4volts and i fix back to 12volts frm 15Amp fuse box later all check light gone and i can start up engine well.My relay same numbering as urs too.tqsm sir🙏🥰💕
Wow new subscriber and a very clear explanation of how the relay functions . I own two Hondas and I had trouble with one and was a cracked solder joint on the board . Repaired board and no problems since . And yes I keep a spare handy . Thank you for sharing this very important function of each pin . 👍. Artie
Exactly what I needed to find, Now I get to go out and figure this out on a 93' Accord. New fuel pump, Filter and relay but no fuel pump working. I know the pin 1 power is connected and always hot. Hopefully I'll find it now that I know where and how to look. Thanks for this video
Great video. I've got all of that working as you mentioned in the video but pin 7 (relay to fuel pump). I checked it with the red probe to pin seven and black probe to ground and turned the key on but still no volts reading. Did I do it wrong or I've got a stuffed up relay or something? Thanks
I just finished the swap on my 99 dx.. however I am not getting any power to wire #3 with ignition on.. with ignition off it has continuity as well with ignition on but no power.. ignition switch has power to all wires, main relay is good, ecu is good.. they have been tested on a different car.. I have 3 grounds on engine bay (transmission case, valve cover, and intake manifold) fuses are all good.. I’m am running the Rywire budget harness V2 with the Hybrid Racing conversion harness.. any ideas?
Hi is the immobiliser built in the main relay as well. Lost all the keys. Cut a blade/key, but won't start car. Do you know if a HONDA ACCORD 1992, 2.2, has immobiliser module. If so do you know where the immobiliser unit will be. Thanks.
Is it bad if u constantly pull it out to prevent theft ?? And is that relay grounded to the car ? Aski g so i dont have to constantly unscrew it just to pull it...can it just sit lose on side of glove box ??
I have a 2002 honda civic lx 1.7 with the key in the on position not cranking just on , the fuel pump stays priming and wont shut off, any ideas if it might be the main relay ..? Ive checked the blue relay and brown relay behind the glove compartment and they seem to be doing their job , please help
Great video and information I did not know. I think my K swap harness is wired for all this but who knows. It is an old car so will buy a spare. Thanks
hello, thanks for the video. i have a Del sol vtec turbocharged. it starts perfectly even after parked for long time, but after around 20/30 minutes run i can hear a clicking coming from the relay and the engine hiccups. could this be caused by some old wire or something? thank you
Hi my Honda Civic 2.2 diesel the year 2007 mk8 is not going to sleep when I drove for less than 10 minutes it seems that the main relay is still energies until I switch the ignition on and off than the main relay will denergies any ideas what cause the main relay to stay energies
@@NateInSaTx sure . The oem Honda main relay dose 2 separate function. One fuel and one as your main power source. If you can find a wire diagram for the oem main relay you will see 2 different function. Hope this helped you
Merci monsieur...Traduction en français..Is it the same process for a Honda jazz 2005 ..I have the same problem.Can you help me Sir. MERCI Monsieur.. How to find this swith and where is it situated..Merci... Watching from France... Monsieur..
I have a 98 Honda Accord DX and my slot three on the main relay actually has two yellow wires positive and negative identified or what has a straight one doesn't but they're both yellow and there's definitely two wires
I did the test for ground and I didn’t have no beeping sound, I don’t know what else to do, my ecu is not turning on and my fuel pump is not activating and im not having check engine light on the dash, I even bough a new relay from jdi company and I still have no power on the ecu
No you don’t. The main things you need are the OBD1 Distributor and the ECU along with the MPFI wiring. You can even use your original injectors, as long as you keep the Resistor box.
Probably not, but it is the first thing to check for a crank no start. You can still crank the engine with a bad main relay but when they are bad you won't hear the fuel pump prime when you turn the key.

Brooooo I remember you from 2004 when I needed. A obd0-obd1 jumper harness
Your an o g in the game
Great video. Not a lot of people realize there are 2 relays in a main relay.
Very true!
That JDI main relay conversation is not a good idea as far as the fuel pump running at all times go ?
@@albono780 I dont suggest any aftermarket solutions when it comes to that.

Hermano, beautiful video very very well explained,its a first time somebody explained like that.God bless you.
Thanks Ryan. This might be my issue. 00 Integra with 07 K20Z3 swap. Cylinder 2 and 4 not firing.

ground the solid black
You explained it just perfectly.
So could i tap my positive wire from my IAB's into my IACV yel/blk for a +12v? Or will this end up interfering with the voltage?
This video is really helpful i got my crv fixed!!
Hi is the immobiliser built in the main relay as well.
Lost all the keys. Cut a blade/key, but won't start car.
Do you know if a HONDA ACCORD 1992, 2.2, has immobiliser module. If so do you know where the immobiliser unit will be.
Thanks.
Do you have a video just like this on the obd1 relay for the early delsol like a 93 d series???
i have a 95 Civic Coupe. Hope I won't need to replace the relay anytime soon.
This video helped me out. Thank you!

So I could connect a defroster 12v to the fuel main relay as a kill switch at pin 5
Thanks for telling us what to do when we order a new harness and it doesn’t come with a main relay plug 😢

Glad it was helpful!
Thanks Ryan! This should help sort out intermittent no start.

There are a few companies now that make a Honda main relay adaptor harness to convert it to a regular automotive relay.
This video was designed for oem Honda main relays, thanks
It will work You will need to add 2 relays so that it can work correctly .
@@albono780can you elaborate?

Do you know what could cause #6 to have no power during an attempt to start. All other slot tests match your video.
My 97 civic when I try to start it the horn blows and I have no power going to the starter what would cause that
The main fuse goes wild with clicks when I'm trying to start it
My 98 v6 dont start I have another accord 02 and try the main relay and work on the 02.

Hey bro name is ronnie. I have a 2001 Honda odyssey with the main clicking.im getting gas to fuel rail but no spark from plug. Help me please
If I were to convert this to a 4 or 5 pin relay how would I do that?
Dont, use the relay honda intended
I did the test for ground and I didn’t have no beeping sound, I don’t know what else to do, my ecu is not turning on and my fuel pump is not activating and im not having check engine light on the dash, I even bough a new relay from jdi company and I still have no power on the ecu
Ground pin 2 on main relay and turn ignition on second position to see if ECU is on and fuel pump is priming.
@@channtriatoun3844 I will try that thanks
Did this help your situation? I’m having the similar issue
@@bandotarzan4160 my problem was that I had the plugs on the ecu connected in the wrong port lol
👍🏻👍🏻👍🏻
Could you show us how to replace that relay with a regular relay?
Can we swap it out or rewire it with a diff one good question
Please keep honda relay
97 ek gsr swap
Rywire harness
I’m getting 12v thermostat ground/main relay ground/driver side shock tower ground
HELP ME PLEASE!!!
If I use a rywire harness to obd1 convert my EF (sticking with the stock engine), will I need to change my main relay to the later pinout too?
No.
no, this video was made for 92-01 chassis...
No you don’t. The main things you need are the OBD1 Distributor and the ECU along with the MPFI wiring.
You can even use your original injectors, as long as you keep the Resistor box.
@@the4thgen_tfl gotcha.
Thank you
U are the fucking man fixed my car 🙏🏾🙏🏾
I'm not getting a beep on the black wire
Could this relay be part of a no crank no start situation?
Yes very alot..if you know how to solder you solder the points first before going out to buy one unless youre rich of course
Probably not, but it is the first thing to check for a crank no start. You can still crank the engine with a bad main relay but when they are bad you won't hear the fuel pump prime when you turn the key.
Or the ecu is bad
If the u think the ecu is bad you pop off the lid and get a hair blow dryer and use it til the fuel pump primes
My PIN 2 is only getting 2.5 volts can anyone help?
Well not on the older Hondas they're under the steering column under the steering wheel
How if don't have power on the white wire
bad fuse?
Just swap my rsx it only cranks no start all grounds connected
Thus I'm having a starting issue
Hell I might be able to drive my car again
Need some help

Wtf..ebay lol
