I have a 1999 Honda Accord that occasionately shuts off while driving down road. First thought it just ran out of gas but running out of gas would not shut all electrical systems down. Anyone have any ideas?

First, check for a faulty MAP sensor, which controls ignition timing and air/fuel mixture through inputs to the ECM. Problem most likely with the electrical side of the MAP sensor, rather than the vacuum. However, both are easy to check out. Turn ignition on and check for 5v. going between + reference wire and - ground. Check for 5v. also going between the + signal wire and - ground. If you don't have 5v., then the problem could be with the computer not delivering the necessary 5v. to the MAP sensor. Second, check out your main relay.

Let me know if this solved your problem.

It sounds like it might also be the ignition switch. There is a recall on 97-2002 Accords and CR-Vs because of the faulty ignition switch, which can cause the car to stall in the middle of driving, like someone just pulled the plug on it. I'm having the same problem with my '95 Accord, which has the same ignition switch, but for some reason was left out of the recall. I was having the "Hot Soak" starting problem (main relay, prob.) but now it won't stay started at all. I had noticed my needles and guages die intermittently but they came right back. Then it just died while I was driving it, and I've only been able to get it to start again by messing with the ignition switch, which I hope to be able to replace soon. I will check the MAP sensor, as well, though. Where is info on checking the MAP sensor?

i had the same problem on my 95lx ... it was the electrical portion of the ignition switch. took me about 1 1/2 hours to swap out and the part ws $44 at the dealer. hell of a cheap fix for such an enormous problem. thanks for the post on this, guys, it really helped me narrow down my problem!

That's finally what fixed mine, too. That things should be recalled, IMHO. It's to squirrely a part to have so much potential for sudden and total wipeout!

My car has had the same "engine shut off" problem since 2000 or 2001 which I have taken to the dealer twice and each time they did not find a problem. Now I am well beyond my warranty and will have to pay for the repair.

I called Honda [1-800-999-1009] to see if my vehicle was included in the recall, it was not. I was told that if enough cars were reported to have had this issue seperate from the production line that recieved it, a recall could be sent out. If your car is under the recall and you have paid for the repair they will reimburse you for the cost.

Everyone should check to see if their accord falls under the recall listed below. If your car is not covered get the problem documented with Honda Corp by calling and reporting it and what you paid to fix it even if you did the repair yourself.

I have an appointment tomorrow for a possible starter solenoid contact issue [my car won't start at the first attempt] I am wondering if this is related to the ignition switch issue. either way if my car dies in traffic and I can't restart it I am screwed, it's a very dangerous situation.

I learned a lot about this in my call and how Honda handles these issues. If anyone wants to know more let me know...

Check the ignition on the car, where the keys goes...for me it was worn out probably too heavy a key ring. Its an easily fixed problem...about a $20 part. THe dealership couldn't figure it out.
The car turns off while your driving...I bet if you hold the key forward the car will stay on.
