First check whether the battery connectors and terminals are tight and clean. Also check for any loose ground wires in the engine compartment, including the one connected to the thermostat housing. Another possibility is that the ignition switch on the steering column is bad.

Welcome to a great site for Honda owners.

Do you know about the Main Relay Problem with hondas?
for those that don't read on.

I will assume that you have followed the standard advice that you are going to get at the outset of any troubleshooting journey. Plugs, wires, cap, rotor, fuel filter, tune up.

I have a 90 civic that I bought a couple of years ago,
my first honda. Great looking, well maintained ( as in a full folder of info on everything that had everbeen done to the car) 175,000 miles, new for a honda.

I got it for 600 bucks, it was a steal.
Until the weather got hot outside.

When thetemperature was above 80, and you stopped at Quicky Mart,and then tried to restart in 5 min. You never knew if it would start. The engine would crank just fine, but no spark. No CEL, no fault codes, and the fuel pump ran.

Let it cool off for 15 min, it would start and run just fine.

I searched this site and found that there were a lot of people having weird problems with starting and stalling.
A large number of them were related to the main relay.

All electrical power goes through the main relay; fuel pump, ignition switch, ecu, spark plugs. This thing gets hot!
And I mean hot to the touch.

The solder joints from the factory were not that good, and with repeated heating and cooling they tend to fail when hot.
They cool off for a while, and remake connection, and everything works again.

You can pry the main relay apart and reheat the connections and usually fix some starting and stalling problems.

This seems to be an almost universal problem with honda's
that everyone fixes and then forgets about.

There is info inthe problem solve areathat will help if this is your problem. And a lot of the guys here can point you in the right direction.

Good Luck

You are correct when you say that the main relay controls the fuel pump. It also controls power to the fuel injectors and ECU, but not the spark plugs, ignition switch, or most other electrical components.

i had your problem last summer in my cadillac. i switched the wires to my battery from side post to top post and i didnt get one of the wires tight so it moved around with the vibrations and would loose electrical contact and i would loose everything. sometimes only for a split second, others i would have to drop it into neutral real quick and try to restart it. not fun when you're on the highway. anyway i tightened my ground wires and it took care of the problem. so like ronj said, check your terminals and grounds first then move on from there if that doesnt fix it.

98civ, have you taken the car in for the recall of the ignition switch? you can double check with american honda. you can evencheck it on the website by punching in your VIN #. but it is a known issue for the car to just turn off even at highway speeds and so they will replace it free of charge if yours was not done earlier.

When you find the problem please post the answer.

RonJ and everyone else are spot onwith checking the electrical connections. Withweird electrical problems the first thing I do is check the connections. Even if they look clean, I still clean them again. it only takes a thin film of oxydation to cause problems. And it's free.

I need RonJ's advice on my problem, and I mean no disrespect. But I need to make clear what I mean when I say that the main relay controles all electrical power.

There are 7 connections on the Main Relay.
They deliver 9 signals, 2 of the connectors have double wires.

Ignition, Battery, Ground, Start Switch, Fuel Pump, and 2 ECU
connections that actually provide power to 4ECU inputs.

After you check all the electrical connections in the engine compartment,if you still have the problem,I would suggest the relay.The relay solder joints are a known problem,and if you lost either the battery, or the ground connection, I would expect the car to die, and perhaps lose power to variousareas.

One of these connections goes to the ECU that controles
spark signal, and so some people have strange spark problems.Terminal 1 and 2 are battery and ground, and these are the ones that I would reheat the solder connections and see if that helped. It's free. Ron J provided me a link to a site that had instructions that solved my problem. Once again with so many inputs, into a known bad connection it only makes sense to take the relay out, pry it apart, and reheat the solder connections inside.

I know this is an old post but if this helps someone... I was having the exact same problem, well low and behold it is a safety recall issue. Thank you mundy5 for the suggestion, my garage had incorrectly diagnosed the problem, you just saved me a bunch of $$$.

Important Safety Recall: Ignition Switch

Dear Accord, Civic, CR-V, Odyssey or Prelude Owner:


This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

What is the reason for this notice?
Honda Motor Co., Ltd., has determined that a defect relating to motor vehicle safety exists in the ignition switch on certain 1997 thru 2000 Honda automobiles. Electrical contacts in the ignition switch can wear prematurely due to high electrical current passing through the switch. Worn out ignition contacts could cause the engine to stall without warning. Although the engine will restart in most cases, if your engine stalls while driving in traffic or at highway speeds, you're at risk of being involved in a crash. Difficulties starting the engine (for example, hard-to-start, stalls immediately after starting, etc.) may indicate that the ignition switch is failing.

What should you do?
Call any authorized Honda dealer, and make an appointment to have your vehicle repaired. The dealer will install an improved ignition switch, free of charge. Please plan to leave your vehicle at the dealership for half a day to allow the dealer flexibility in scheduling.
