I have a 1991 Honda Civic Hatchback. A few times I put the key in the ignition switch, turn it, and click! Nothing.. If I keep trying it, eventually it does click and start.

Now this usually happens when I've been driving for awhile, and then shut it off and let it sit. It happens the most when the weather is fairly hot, and the car is sitting in it. Like when I go grocery shopping.

I read somewhere, that the main relay could cause this, and that sometimes the solder joints separate, causing the relay to work intermittently. And that you can take out the relay, and re-solder the joints to fix it. So I tried that, but it still does the same thing.

So I'm not sure about what would cause that. (Ignition switch?)

Another problem this car has, is after starting, and driving for roughly 10 minutes, the engine bogs down, and almost dies. If I floor it, it speeds up and runs fine, and I have no more problems.

I thought.. fuel filter. Since I never have replaced it.

So I replaced it, and put it all back together. Tried driving it again, and it now bogs down a lot more. It still runs better when I floor it, but then it returns to bogging down shortly after. It seemed to run better before I replaced the filter. Any ideas on this?

Prior to the fuel filter replacement. When I was on the freeway, and driving at higher speeds, the check engine light came on after de-accelerating from 65 to 55 or under.

It happened, after holding a higher speed for more than 10 to 15 minutes.

Then when I dropped the speed, that's when the light came on. If I pulled over, turned off the ignition switch, then restarted, and got on the freeway again, the light stayed off for awhile, but then repeated the same process all over again.

Could it be the O2 sensor? I'm running out of things to try here.

Other than all of the things listed above, the car is great! Gas mileage is about 30 miles per gallon.

So I don't know what it could be. I haven't checked the codes, I'm not sure what type of code reader to get OBD I or OBD II? Or even if those readers will work or not with my car.


Thank you.

. Check for codes, when the Check Engine Light comes on:

Reset the ECM, after you fix whatever is causing the CEL to come on, by disconnecting the negative battery cable for 10 seconds.

. Replace main relay, which is located just above the fuse box.

. Replace the Ignition Control Module (ICM) and coil:
