Crank No Start - Honda PGM-FI Main Relay
ฝัง
- เผยแพร่เมื่อ 15 ส.ค. 2019
- This is video on crank no start issues on a Honda. A crank no start can be caused by many things including a bad PGM-FI (Programmed Fuel Injection) Main Relay. If the main relay goes bad, it can cut off the fuel injectors and the fuel pump. The exact vehicle in this video is a 2000 Honda Civic LX Sedan. Enjoy!

I have a 2000 Honda accord ex v6 that has a crank no start
@@travondewayne2758 year old video that doesn't get seen apparently. Did you ever figure it out?
Bro, I have a problem with my Honda CR-V it cranks but wont start, and I have changed the distributor, we have spark but not start.
What could be the problem??
@@egvideos7093 did you get it going.?
.in FEW AND ONLY A FEW, Remove the ECU WIGGLE THE IMMOB. CHIP. IT'S VERTICAL& HAS 12PINS. RAPIDLY WIGGLE UNTIL IT BREAKS CLEAN. IF THIS DIDN'T WORK GET AN EMULATOR IMMOB.BYPASS CHIP ONLY USING PIN.1-4-8-10-11-12..REINSTALL AND G LUCK
I spent 2 years getting an associates degree at an auto trade school. Spent 8 weeks in electrical theory and operations class. I have never heard a wiring diagram explained so simply. Thank you. The industry needs more teachers like you.
Very. You

Once you understand how the relay works the diagnostic procedure becomes much easier. Your a Honda expert!
I agree! Congrats on 3k subscribers Wyatt and thanks for the comment!
This sir is the best video on Honda fuel systems ever, thanks so much
Excellent video sir. The diagrams and short precise explanation make this one of the best how to videos on any platform out there. Thank you for sharing!
Glad this video is still up. Been having the crank/no-start issue on my '04 Pilot for a while. Intermittent but happening more frequently. Finally decided to take it in to the dealer. A month-long wait to get in. Searched and found this video. Thought, what the heck, why not try it out. Got the part, installed it, haven't had it happen again. Cancelled the dealer visit the day before. Probably saved me 400 bucks.
Thank you for putting the part number in the description! Mine just went on the fritz out of nowhere! I could not find PGM-FI main relay anywhere because they have them listed as fuel pump relays because that's pretty much what they are but I wanted to make %100 sure I got the right part since I had to order online and got it for $24.99 off of RockAuto, which is a Godsend because I start work next week and needed it fast and cheap!
👍
I've just watched the video and it helped me start my client's CRV.
Africa, Namibia 🇳🇦
Wow I love the way how you beautifully explained and educated us about the PGM-Fi main relay you're really amazing. We highly respect and appreciate you sir
Been struggling with my 98 crv for ages until I saw this. Thank God for the internet
Where is it located? I’ve got a 99
@@alexandermueller4115 in between the dashboard and passenger door compartment
@@widaro7066 I found it, thank you!
Thanks for this. Honda shut down on me twice. 2nd time in the middle of an 1800 mile trip from Idaho to Alabama. Managed to get it restarted and to a napa. Bought the part..and boom. Rolling again.
This has the same engine setup as a 97 Honda civic. Great info for me, put this into file for later if needed. Thanks for the great info.
Glad it helped, thanks for the comment!
Very well done video. Refreshing to see one done correctly and succinctly.
Thanks!
Really good video, COMPLETE information and you made it clear and understandable. Thanks a bunch
Thanks for the comment 👍!
YOU’RE THE MAN. TAPPED ON MINE AND IT STARTED RIGHT UP!! 2001 Accord +300k still kicking
👍
Had that exact same problem where my 93 Del Sol wouldn't start when hot outside. That solved my issue thank you!
Thanks for simplifying the problem-solving issue.
That was super easy. Love the extra details!
Very well done. Informative with no frills. Thank you. And please do not forget MAUI.
Thanks for the info!!!
Just had a crank no start symptom on my 99' civic lx after a cold 5 degree night. I took this main relay out, set it inside to see if letting it warm up would do anything. Plugged it back up after it warmed up a bit and she fired right up! time to get a new relay.
👍
Thx Big Dog! I'm going to make that fix as soon as the part comes in through the mail
👍
Good info as always Dave. Thanks.
Thanks Mike!
Excellent video! Really helpful, thanks!
Glad it was helpful!
Many, many 🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼 thanks
For the schooling this afternoon
Glad it helped, thanks for the comment!
Thanks for the tips regarding main relay
You bet 👍!
This was explained so well. My 99 civic occasionally won't start, but cranks over well. Then it might be weeks before it happens again. I was thinking that maybe the igniter was bad.
Thanks for the comment!
Bad igniters usually stop working when they get hot. When they cool down again they will usually work for awhile until they get hot again. If your car won't start when the engine is cold, it may not be the igniter. My '98 Civic had a recall on its igniter around 2003.
Excellent video thank you for your work
Dave I like your store. Have added quite a few items to my wish list. I like the stinger smoke machine. Seeing as how my cars are getting older but very well maintained it looks like a good machine for the DIYer. Have quite a few of the tools because I purchase as I see you use them. Will also follow you on Twitter. 👍👍👍
It looks like a decent little smoke machine, and a lot less money than the OTC one that I have. I appreciate the support Arthur!
That hat is dope! I'm following you on Amazon now. You'll have to tell me about the first time someone recognizes you and asks for a selfie (yeah, I don't count). Great video!
I'm almost famous! ok, not really!
Thanks for the tips i learned something today so its not a wasted day
👍
Thank you, very useful information
👍
Sheesh! Thank you for the knowledge! That is much appreciated!
Bravo my good man. I do believe you just solved my issue on my 98 Honda CRV. Took off from work and drove a block or so and Blaahhh, no power and 5-10 MPH. Misfire and just suddenly ran horrible. Found the insulation on distributor gone where wires come out of distributor and replaced distributor, cap and rotor and still no run.Spark to cylinders and fuel to filter but didnt check fuel injectors. Great video dude.
I appreciate the comment, thanks!
Hi Dave, hoping you can help me here. 92 honda prelude with 95 honda accord engine swap about 5 years ago (f22b2 now) I have replaced wires, plugs, external coil, and distributor and It will randomly not get spark (still turns over but no fire). Grounds look good, no cracks or burns in ecm board. I'm completely stumped and have no ideas left PLEASE lmk if you can point me in the right direction.
I have a 95 civic dx. It will sometimes run for a day before shutting off randomly or 3 minutes after I start it in the am, then I get a crank no start for a few minutes before deciding to start. Sometimes it happens at high rpms sometimes while holding the throttle steady. You think this could be a main relay starting to give out?
Great video bro
Great help on my 96 honda crv
Well done!
Could the PGM-FI relay cause any transmission issues? The program I use is suggesting I check the relay. It just seems odd to me it wants me to check that. No fuel issues on the Honda I'm working on.
2007 honda civic, will start for 2 seconds then shut off. At times it will run again with no issue. Would this be caused by a faulty relay?
You are so amazing I'm subscribed now thank you sooo much
Very helpful tips 👌
Thanks 👍!
My 1987 Honda SI is having difficult crank / no starts with a cold and warm engine. And yesterday my PGM FI light came on, for the second time in a month. My mechanic says it’s the starter. My research indicates a possible bad ETC sensor, on maybe a main relay- which brought me here. Any thoughts?
Very good and simple
👍
Good video and informative
Thanks!
Well done.
Thanks 👍!
Thank you so much
Had some solder joints crack/go bad on my furnace relay. Reflowed with fresh solder and all is well. Saved me $250.
Thanks for the input!
Great video thanks
Hello mate I'm just asking if there's a starter cut relay on automatic transmission on 1996 honda civic? Thank you🙏
Have taken my '08 Honda Civic to three mechanics and no luck; cranks but no start. After I crank it a number of times and turns on, the exhaust smell is very strong and pungent. Not sure what this could be. I adjusted the valves as one mechanic recommended. Any tips? Thanks.
Thanks for sharing!👍👍👍
You bet 👍!
Nice Info , i geus i have the same problem with my Honda Deauville NT 700. tumbs up'.
Very helpful....Thanks a bunch
Glad it helped, thanks for the comment!
Hi!
Just had a question, my cars main relay is fine and works normally, however my car sometimes decides to not start and continues to blow the 15a EFI/EM fuse and does this for about 3-7 fuses before the car decides to start again, not sure if it’s a problem with a short in the wiring or if it’s the main relay, fuse doesn’t blow when the main relay is unplugged
i have a montero sport (diesel) w/c has the same symptoms and when i scanned it, it threw out a p0628 code. is that the same code these honda emits when they have a bad main relay?

My main pgm fi relay yellow with black. Line melted n white with green line melted at the same time when turn to acc then if u just turn the key to start acg s 15 amp fuse pop.. changed new wire harness new relay still melting ??
Hi,You think this PGM relay would cut spark as well if its not working?great video by the way...!!
I have a 97 Honda Accord 4 cyl. it turns over but wont start! The gas guage shows it has less then a 1/4, regardless if key is in or not! not sure what that means? I put two more galeons in to test, it still wont start. what should I do first? Thanks Paul
@Big Dog50001 Automotive how do I get to a 06 crv main relay? I think it's right side of steering wheel behind the dash but don't know how to find it
Would this be same for a 1988 Acura integra RS?... I'm having a crank no start issues when the weather is warm outside ... when I know the car works, I will quietly hear the fuel pump engage.
My Honda wouldn't start so replaced the main relay. Started right up but now still on hot days it has a long crank before running. When it's cool it starts right up. Do you have any idea what that would be? I notice on the relay I got its just solder joints, no boxed relays like the original
Will a blown main relay wipe out the ecu 15a fuse? The set up is an obd0 b16a.
I have a 2007 accord that has a electrical issue, several meter lights will come on and the Navi will lose its code sometimes radio will also. The car has not stalled on me yet I have replaced several parts and a couple relays. Any idea what I should try next?
Have an 05 are my relays in different locations or is it on the driver's side in one unit
I tried looking at my main relay to diagnose a crank no start condition. I left the main relay housing bolted into the dash because it was so high and hard to get to (98 accord). I figured to just pry the inner circuit board out of the housing, using a screwdriver in the little indents. But as soon as I pulled the circuit board out it SPARKED and left a little burn. I realized I left the keys in the ignition which was a bad move. The way I was pulling the circuit board out, the gold contacts were sorta loosening from the wire connector…
Basically, im expecting my main relays fried but im wondering if my ECM could have been shorted… because I noticed my OBD2 Port wont communicate with a scanner.
What if i can bang my steering wheel and then the thing will start, usually just when the cab of the car is hot, doesnt happen in the winter as much.
Any idea what part around the key switch that could cause that?
Thank you!
👍
Nice video! How did you get the bolt off? I been trying with a 10mm wrnch with no luck it wants to strip it away..although I must say mine is underneath my hood latch on the floor so very hard to get to as the bolt is high up there..so I gotten it off changed relay unfortunately still hasn't fixed my issue. I do have an appointment tomorrow not looking forward to pay 80$ on a tow for under a mile away any other advice would be greatly appreciated..
Use vise grips. And some pb blaster. Works like a charm
Will it make a tapping noise if it's gone bad?
I have a 2000 accord dx. My fuel pump relay doesn't have any small relay s on the inside of it. So is it the wrong one for the car. Problem is a no start
Man this one got me for awhile. Power to the pump connector unplugged. Connect the plug to fuel pump and no power. This one is under the dash nowhere to be seen lol, at least I know its either that relay OR the PCM
Excellent video Big Dog!
Thank you, I appreciate the comment Joe!
I have a 1996 Honda accord lx 2.2l sometimes when I put the ignition switch to the on position it takes a while to hear the fuel pump activate then it will start I know when it activates cause the check engine light will go off does that has to do with the sensor you've talked about or could it be the ecm?
Another channel says it the computer on the passenger's side. ..I think. Peantbutter something channel.
I replaced it n it still doesn’t turn my fuel pump on but when I take it out and test it it works please help
So my 2004 Honda a cord ex sedan 2.4l when I goto start it it starts but sometimes cold start it makes a weird eletric sound and click it’s coming from the fuse box under the drivers side steering wheel
What I heard on what the immobilizer actually does is kill the power on
the wire going to the fuel pump itself. That's why the engine turns over
without starting. If so that would either be before of after the relay. Mine still works, but losing the key, and or a problem with the immobilizer is a big problem.
am having an issue with my immobiliser system,comes on fine sometimes but the next time you may want to use the car it wont show
Would It cut off pump and injectors at the same time
hello i have a civic with crank no start. turn ignition on and its click. When you start the car you will here the relay clicking as well. Is that normal?
Hey I have a 99 civic and my injectors are getting no power ,fuel pump is sending fuel to the fuel rail ,cranks has spark ,starts on starting fluid ,I already checked/switched pgm-fi still nothing car was running fine till it didn’t want to start you do have any idea ?what could be the issue thanks in advance
Great video man, nice wiring description
Thanks!
Thanks!
I missed this comment when it was posted, thank you for the support!!
Thank you , very good explanation , very clear
I appreciate the comment, thanks!
03 Acura TL crank no start, has new fuel pump and if I spray starting fluid in the intake it will start up and I can turn it off and start it again but hour later it won’t start again...does that sound like relay issue???
Hello. Did you ever find out your issue? I have a 2004 Honda Pilot with a new fuel pump but still a crank no start. It starts but an hour later it won’t start.
Iam having issues with my 2000 Honda Civic. I installed new fuel filter, fuel pump. Engine cranks but won’t start. I took the relay apart and on bottom of it the left side one of the shiny silver things was like a bronze copper color? Any help would help a lot. Thanks oh btw every couple hours the car would start but would have a hard time staying at idle and if I give it gas it would like sputter and die eventually.
Unfortunately is sounds like it needs some troubleshooting done, anything I tell you would just be a guess.
Thank you
No problem 👍!
D4 light flashing, car ran good 2 weeks ago never used it since... Tried to start it this weekend light was flashing. It was low on gas so I thought I'd put 4 gallons in. Tried to start it it was cranking but no start, the gas have didn't even move.... Please help...
I took off the main relay, I'm going to resolder and try again
You are awesome. Great, easy and simple elaboration. Short words and to the point.
my car won't crank but the main relay works I can hear the pump and click on main relay, when I turn the key it's just click, do you think possible is the starter relay
I'm having the same issue. Crank no start. I changed a lot of things, distributor assembly, plugs, wires, fresh grounds, checked the map sensor, IAC valve is clean? I stopped cause all I could think was the body control module. I'll check this first before anything else:)
hi i got pgm light on some time while I'm driving when light on car no acceleration no power what's yr suggestion please, thanks
Awesome thanks
love your videos how to remove flasher on 2012 honda crv ex
If you are referring to the Hazard/Turn Signal circuit, they typically do not have a separate replaceable flasher relay. Those models are normally MICU (Multiplex Integrated Control Unit) controlled circuits, which work from input signals from the combination switch/turn signal switch or hazard button/switch. MICU is a smart module inside the under DASH driver's fuse box. There is a relay circuit board inside the under HOOD fuse box that is part of the taillight circuit but those are not normally serviceable without replacing the entire fuse box. Most common issue is a Turn Signal Switch (Combination Switch) failure but MICU failures and wiring issues can also happen. A MICU failure usually means the entire under dash fuse box needs to be replaced. Thanks for the comment!
Great video again! Can I ask, where do you get wiring diagrams for the Hondas? I looked for them everywhere, I can't get any of them.
I pay (a lot) for service info, including wiring diagrams. Thanks for the comment!
@@BigDog50001 Sure, I tought to pay. But to who? I couldn't find any reliable service.
@@PeterM0911 He won't tell you, but I can help you with that. Alldata / identifix or shopkey. All are great, but one these data programs have fantastic wiring diagrams you can highlight for exact locations of components.
Thank u sir👌
Thanks for the comment!
I replaced the engine on my civic lx at first the relay wasn't working because I did have the ground in correctly now no start the pump comes on I can here it I took 1 spark plug off and started it ot I saw spark so I'm clueless
My 2004 Honda Accord has a crank but no start I was told it was my timing belt but my timing belt isn’t broke....where will my pgm fi main relay located on my car please help bc I need my car
Thumbs up, subbed👍
Amazon says PGM-FI Main Relay 39400-S10-003 is not compatible with 2000 Civic EX (5 speed).
Does mine has one?
what if im getting too much fuel?
