honda accord 1999 stalling problem fix for everyone

Hello Freeze/Gabby,

I unfortunately have the same problem. I have been putting up with the problem for longer then a year though. Thankfully my car has only stalled on me when slowing down to a stop and not while moving at higher speeds. The thought of that happening would give me nightmares. Additionally, I normally can tell when the engine is going to stall as I can feel difference when I start breaking. When it does stall, I put the car back into park and turn the car off and then restart. I have not had a problem starting the car back up after this problem occurs. I too have had mine taken in for the recall in 2002 for the ignition switch but had the problem reoccur again a few weeks later.

One question, is the starter relay and fuel relay the same thing? I am willing to explore either or if it is not too expensive if this will give me peace of mind.

Additionally there was a post by a user named Vince.Lum who said the following:

"Hi Digiti, no my VIN didn't fall under the recall but had my dealer
change that but the problem still existed. But now I've had the main
fuel relay switch changed and I've not stalled in over 2 weeks!!!"

Hi guys,

This is all pretty interesting stuff. “Accord99”, I have the same problem when it stalls---it seems to re-start everytime. A few weeks ago, I had a mechanic tell me to take note of three things the next time the car stalls. First, when the engine is in the process of stalling, does the engine light comes on. This is not the same as when the car comes to a complete stop. At that point, the entire dash board lights. If the engine light comes on when the car is stalling, you should be able to bring it to a mechanic with the right diagnostic machinery to locate the problem because of the memory codes in the engine computer. Second, when the car stalls, does it re-start if you keep it in park. In my case, I am turning it over three or four times before it actually re-starts for good because I am quickly trying to throw it into drive from park. Third, again when the car is in the process of stalling and is slowing down, check the tacometer. If the tac goes straight to zero, your problem is more likely electrical. If the tac slowly moves to zero as the car stops like the odometer does, it is more likely a fuel related issue. Of course, these three things are not the easiest things to do if you are on the highway and moving at 75mph (that is how my last stall occurred). You want to make safety your primary concern and steer out of traffic. But if you can, check the tacometer. “Unfortunately”, I have not been able to check this stuff out because my car has not stalled in over a month. I guess that means I am due for one soon, so I will keep you guys posted.

As for whether the starter relay and the fuel relay are the same, I do not think they are (but I am not certain of this). I do know that the main relay and the fuel relay are one in the same. “Accord99”, I know you quoted Vince.Lum who said the main relay solved his problem. I had this changed before Xmas but it did not fix my problem. Since November, I have also changed the ignition coil, distributor, and wires. I also had my ignition switch changed by Honda as part of the recall over four years ago, but none of that worked for me. I am assuming my ignition switch is OK, but after fours years, who knows! As for the cost of changing the main relay, it set me back about $100 by having a mechanic do it. The part itself was about $60 when purchased through Honda.

I am starting to think my problem is the fuel pump (which is what I originally thought). Then again, someone else in this forum changed that part and it did not work for them! Honda also does not think it’s the pump, but they have been wrong before. I’ll keep you all posted with my progress (or lack of it).

Gabby (frustrated, as usual!!!)

Hi Gabby,

I appreciate the extended information. As far as the dash lights are concerned. When my engine stalls, all the lights on the dash would light up. If not all of them, most of them. I dont know if this is important, but recently I have had to hold the starter longer to get the car to turn over (has occured twice now). I'll post again if there are any developments.

Hey folks,

My first post here. I have a 99 Accord Coupe V6. I had it stalled on my two times in the past couple of months while driving on the freeway... luckily I was on the slow lane when it happened. I had it happen 3 days just in the past three days.

The stall occurred without any warnings whatsoever. The engine just cut out quietly and suddenly. Pressing down on the paddle yield no response. On the dashboard, there were not immediatly display of any lights (ie. battery, etc.). Once the car comes to a complete stop, the rest of the lights with come on. It will take 2-3 trys to get it started again but what I found was if you let it sit for about a minute and start it again, it will come up pretty much every time. The car would run find after that.

Anyway, I call my dealer on Tuesday. Since I had the recall done back in 2002, I would have to pay ($250 total) this time around. He said that the problem is the harness part that's right behind the ignition switch that's causing problem. Over time, that part would wear out and would result in stall. I call Honda corporate in Los Angeles and complain about this. My question to them was what's the point of the recall if the recall does not fix the problem as stated. Their basic answer is that recall repair can only take place once.

I decided to do this myself. It happens that my cousin sells auto parts and he happen to have one of those ignition harness. I replace it yesterday. So far this morning, no problem. Only time will tell.

One last thing, I took apart the old harness just to check. The contact plate in it seems to wearing out abit... but not too much. However, I notice that the plate was being supported both two small springs and one of them seems to be weakening. This may result in it not having full contact... just my thought.

Hope this helps someone.

Thanks

Update....

Well folks... changing the harness did not solve my problem. I had it happened to me twice today... one to work and twice return from work. During the 2nd time, I remember seeing the tac slowly moving towards zero.

Anyway, I think the fuel pump may be the next thing for me to look into.

Well... another update...

Replaced the fuel pump... still no stall. I am totally lost now. The only thing left now is whether the OS Sensor and cat converter have anything to do with with cause I have been driving a while with the engine line on. OBD code came back with something about the cat and os2 sensor. I don't believe this should be connected to the stall in any way... but this is just my opinion.

Anyone have any suggestions

All,

Just want to give something back after spending the past 3 weeks troubleshooting my 99 Accord V6 Coupe w/ 210K miles... waaaahhhh!!! I have done the two recalls from Honda back in 2002. Hope my stuff here can be helpful to folks with similar problem. So here I go!

I started getting P0420 and P0401 over a year ago. I ignored it because it is mostle related to emission stuff... at least that's what I was told initially. But lately my car has been stalling while driving on the freeway without any warning whatsoever. The engine just dies but I still have steering and braking capabilities. It started to freak me out. I did quite a bit of research and found various good and conflicting responses (like getting a new Cat Conv) from people out there. A honda dealer wanted to charge $250 just to replace the EGR valve. Rather than spending the money and not knowing if it is going to sovlve the problem... which I have seen alot people saying, I decided to do one thing at a time thinking that solving one issue may remove another. This is what I did:

1. Thinking it might be the fuel pump (or maybe the juel injection), I had my local machenic ($40) do that work for me. They injected so cleaner into the fuel tank (I think) to help burn out the craps that were in there. Well, this didn't help as I was still experiencing the same problem.

2. I than proceeded to replace the ignition harness. This is the part right behind the ignition switch. I got this from my cousin for free cause he sells parts. That didn't help either.

3. I replace (DIY) the EGR valve with a brand new one for $50. Hey, that removed the P0420 code. But the P0401 remains and the car continue to stall.

4) I than found information about EGR Port clog issue on the net. This is a know issue and Honda had announce it at one point. The title is "Accord Warranty Extension: EGR Port Clogging". If you want to do this yourself, you can do a search for ATB 21179-23317 on Google. Honda charge your a few 100 bugs for this. If you have not done this and your warranty is out, you will need to buy the kit as described in that document. Since my car already has it done before, all I need to do is do another EGR Port cleanup. This is basically to remove carbon from the clogged port. MAN! more than 2/3 of the port was all blocked out with carbons. We gave it a good cleanup. I also replaced the main relay wit a brand new one ($40). Finally, I clear the ECU.

If I knew it earlier, I think I should have only performed step 3 and 4. So far, I have driven it more than 110 miles and things seems to be okay. I am keeping my fingers crossed.

Hope this helps.

Hi ultragc.

I also have a 1999 Accord V6 coupe, but lesser miles than your, only 132,000 m on mine. My Accord has similar problem of engine keeps on stalling. It happened twice last week but each time it happened, I was able to restart the car and drove home. Mine tends to stall when I slow down to make a turn. All the lights on the dashboard, or most of them, are on when it stalls.

Your solution of cleaning out EGR port may help to solve my problem. So how do you clean out the port, just remove the EGR valve and spray cleaning solvents directly into the port? And what kind of solvents do you use.

FYI, I already replaced the ignition switch sometime in 2003, part of Honda recall. I also replaced the EGR valve at around 70k miles when the check engine light came on. Luckily, it was still under warranty for the V6.


Thanks for your help.

Hi Accord99JoJa,

Sorry for the late reply. I've been out. You shoud perform step-4 first. Just do a google search for ATB 21179-23317 and you will find the document to perform a DIY.
 >> Stay informed about: honda accord 1999 stalling problem fix for everyone 

Ultrac,

Thanks for your reply.

But this step 4 is already been done about 2 years ago by Honda dealer. It was still under warranty back then.

Any thought. Thanks.

Well, I had my done a 2 to 3 years prior as well. Believe me, this thing clogs up pretty quickly... especially if you drive alot. If you cay DIY, chances are you will see the tube is fill with carbons.

Hi
everyone, I am a new egistered member and read all of the post concerning this problem a few weeks ago when I was having similar problems with my 1999 Accord. Mine was stalling and the engine dieing at slow speeds or when I was coming to a stop. It would always start right back up. Sometimes it would just stall like it was about to die and some of the dash lights would come on and the little warning alarm would start beeping . After reading all the post on here about this problem, I decided to replace the "main relay" under the dash. It still continued to stall and die and after a few weeks, it started to die and when you tried to restart it, it would start up and then die, over and over again. I discovered that I could put the ignition switch in the number 2 ( II) position and jiggle the switch until the dash lights come on and then it would start and run fine. After talking to a representative at
American Honda and getting a case number, they advised that I call my dealership and talk to the Service Manager and they would pay for another ignition switch recall. ( I had this replaced in 2005 on a recall). So yesterday I took it back to the dealer and they replaced the ignition switch (faulty) with a new on for free and that solved all my problems. Hope this helps someone. Dan
