Crank No Start - Honda PGM-FI Main Relay
HTML-код
- Опубликовано: 2 окт 2024
- 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.?

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

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!
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
I use to unhook it from my 95 accord everytime i left the car. Who needs an alarm system? Hhaha
Nice!
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!

That was super easy. Love the extra details!
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
WELL ... My 2002 Honda Odyssey would DIE as I was driving and then a few minutes later i was able to start it up and drive . I took it to Honda in hopes to get it fixed = they call a day later and said it was working perfectly and to pick it up ??? I looked up the problem and found it was the MAIN RELAY - I told Honda to replace it ( they laughed and said a RUclips video can't fix a car) ...They charged me $480 dollars to install that part ! Autozone sells that exact same part for $80 dollars and it just plugs in under the dash board !!!! I now have 500 miles on it on city streets and heavy stop n go traffic on the expressways and ITS WORKING
2000crv ex 5 speed morning staring ok like 35 m driving it put it off no want to staring ogaing way like 25 m maby lilte be mired and stared thing it the main realay thank s much
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
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.
What if the relays work would the computer be bad
My 2006 GMC envoy. Will start when it's cooler outside but when it's hot outside or if been driven and warmed up the car will crank but not start
Will this relay failure give you no spark?
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.
Really good video, COMPLETE information and you made it clear and understandable. Thanks a bunch
Thanks for the comment 👍!
Hello sir what's the problem of my Honda Civic matic the engine is good but when I put it into reverse or drive it won't run at all?
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
I have a 2004 Honda Accord EX 3.0. The car starts, but all the gauges except for the green key do not work. The dash lights up when you start the car, then fades out. No wipers, no turn signals, no power windows, no AC compressor. Car gear shift will not leave Park. All fuses inside and out test okay with meter.
I've just watched the video and it helped me start my client's CRV.

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!
Hi,You think this PGM relay would cut spark as well if its not working?great video by the way...!!
@big dog50001 automotive my car will backfire after driving for a while then won’t start for thirty minutes and then I’ll run. Could this be the cause? Thanks
Possible, but unfortunately quite a few things could cause that. I would verify that the Engine Coolant Temperature (ECT) sensor is reporting the correct temperature to engine computer (need a code reader or scan tool for that).
Okay bought a new fuel pump relay installed it still no power to the fuel pump. So I unplugged it went to go check the plug connector for power. I'm getting power to the ignition wire no power to the fuel pump I'm just wondering if this could be a ECM PCM problem
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
Very well done video. Refreshing to see one done correctly and succinctly.
Thanks!
Good info as always Dave. Thanks.
Thanks Mike!
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?
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.
Excellent video! Really helpful, thanks!
Glad it was helpful!
I have a 2000 Honda Civic that was doing exactly what you were describing. I went out and located the PGM FI relay. I then tried to start the car, and it did not start. We tapped the relay, and she fired right up. Normally I would have to wait 20 minutes. Went to the parts store and purchased one, installed it and the car runs great now. Thank you for this video. You saved me so much time and effort. Thank you for posting the video.
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.
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
Amazon says PGM-FI Main Relay 39400-S10-003 is not compatible with 2000 Civic EX (5 speed).
Does mine has one?
😂😂😂 amigo that system is call more weight to any car i have the base CRX duel point fuel injector system pgm-fi with a 272 Delta cam regrind and 10 pound flywheel and 2 stage clutch kit header bore head y8 head gasket and others things and i can say my is real fast and the duel point fuel injector system pgm-fi work beautiful in my settings the reason is because the segundary manifold runner are shorter than primary runners meaning work beautiful with the higher rpm cam and is not any problem with fuel delivery at all and i put my to 72 to 75 RPM range all the time because i put crowler springs and retainers and like i said before i don't have problems with fuel delivery at up plus the pmg-fi system is a lot lighter and easy to maintenance then the multiple fuel injector system and less cheaper to maintenance and like i said from junkyards parts and im a backyard mechanic nobody teach me crap i learn my own self to build car by using logic and common senses and understanding the law of nature i port the manifold mild way inside out and build my own airflow system but i can say i hate multiple injectors system a lot of computer crap sensors etc and all for air and fuel ratios jjjj 😁 really for real hell know CCR born in the byouooooo take care gd video amigo
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.
Afternoon, My Name is Craig from South Africa, How to Bypass The PGM Relay on a 2012 Honda Accord 2.4l
What can be the issue if we replaced the fuel pump now getting over a 100 psi fuel pressure? 2000 honda civic ex 1.6 d16y8
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 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
One of the easiest subscriptions ever!!!!!
Is it possible that the PGM FI module can contribute to a no spark issue?
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
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.
I crank but won’t start I sprayed strarter fluid it runs for few sec then dies it’s an Acura tl 04 changed fuel pump still same problem and I can hear it prime
Great explanation 👌 i have this same issue but my main relay clicks like a machine gun when i turn the key to on. Any idea what this could be? I tried another relay and had the same issue
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.
👍
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?
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!
My accord crank no start but I’m getting fuel to the injectors and take gas’s feed out and crank have fuel flow I can not find the reason why she does not want to start
Will a blown main relay wipe out the ecu 15a fuse? The set up is an obd0 b16a.
The video should be called if you can’t here the fuel pump this what you should check
Thanks for stopping by!
Saved me from selling my civic😂 thank you
👍
wish this was my case..../:
im getting toooo much fuel/ plugs are wet with gas.
and dont know how or what else i can do.
Mine lost power while driving, and then i had to floor it to start it. And hardly start..and now wont start anymore
not one of these videos have anyone showing the actual start and the noise its making. Vital part of the diagnostic
Changed the main relay and still crank no start.. I have no power going to the dash
where does that really go??
Would It cut off pump and injectors at the same time
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!
I have a 1998 Honda crv . It will start them randomly die. Wil start up possibly drive for few days . Then randomly die . Now few months later it will either start then immediately die or just turn over and die instantly? Tried switching main relay , but that didn’t work. Any help would be greatly appreciated.
There are a few things that can cause this, so it would need some troubleshooting. A quick check on the ignition switch that I like to do (not foolproof though): Start vehicle and get it running (in park), then wiggle key around in the run position and try to get car to stall. If you can repeatedly get it to stall by wiggling key in the run position then a bad ignition switch is what I would be leaning towards.
@@BigDog50001 I tried this . While it was running it had no effect. I was leaning towards fuel problem. It’s not main relay, I gonna check fuel pressure. I will just keep going down the list until I nail it down
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
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.
With that relay cause it to not to deliver fuel properly...
Where is the ECM relay on a 2005 Honda element ?
what if im getting too much fuel?
For the algorithm 🤓🥳💪👏🤙🤔😎
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
I have a 2011 v6 accord. Got a check gas cap message and shortly afterwards p0456 canister code but car was fine. Bought a new Honda gas cap put it on and 24 hrs later p0456 and lean both bank p0171 and 174. Now car won’t even start. Anyone please?
Very well done. Informative with no frills. Thank you. And please do not forget MAUI.
I hope this is what's wrong with my 97 Civic I replace three distributors thinking that's it each time. Thank you for this video I'm going to try replacing this
Automatic or 5 Speed?
@@angelisone 5 speed it's running now they said it was a PCM they had to replace it but now it's idling really rough
@@jdmchickkustomz9417 PCV & PCV Hose & that Black Box (cleaned) replaced?
Remove the hose to get to the Throttle (flapper) and clean the outside as well as the inside.
Check all rubber hoses for cracks/worn
1. coolant low or air in system
2. air idler control valve (screen dirty/seal), replace seals
3. fast idle thermal valve, remove & clean & replace 2 O-rings
4. Intake Manifold's gasket & Fuel Injectors O=rings
5. all O-rings/gaskets/hoses/seals should be replaced
And in the Accord 2002 where is location?
Porque el mio tiene un ruido raro al dar ingnicion
Verified that having 1993 Honda Accord tapping on the main relay in the video under the steering column does temp fix the issue.
I had a 90 Civic with the glass lift back base model, for two years I was plagued with it not starting, we would park the car in the morning and ride share, get back in the car at the end of the day, very hot outside, no start 45 minutes of trying, it would always start in the morning (cold), I took it to the dealer, they charged me 450 bucks and it still not work, hot and stuck. The parts guy at the dealer figured it out, Fuel Relay Switch, it looks different than the one shown.
I have a Honda Amaze diesel, my car is not cranking and not turned on ignition too after covered approximately 1000km. Any one know about this concern comment.
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 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.
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
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
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?
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
1990 Honda civic in mint condition driving it at 35 miles an hour sounded like it ran out of gas all the test I’ve done have shown it is not the fuel pump I even though I put replace the fuel filter. All the test of shown it’s not the fuel pump the check engine light does not come on whatsoever which makes me feel that it is the main relay which I hopefully will be working on it today yes I’m a female
Nice Info , i geus i have the same problem with my Honda Deauville NT 700. tumbs up'.
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
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.
Can a bad pGM fi affect automatic transmission shifting problems
Doubtful. Hondas typically have 2 PGM-FI relays and they usually control power to a lot of components including fuel delivery. Typically if one or both relays drop out the vehicle will not start or will stall out.
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 ??

Where was this part located? I’m having trouble finding it on my 2005 Honda Pilot
They should be under left (driver's) side dash area, to the left of the steering column. There should be two of them, one for fuel pump and one for fuel injectors.
Had that exact same problem where my 93 Del Sol wouldn't start when hot outside. That solved my issue thank you!
