I have a 92 Civic LX that has problems starting under certain conditions. If I try restarting it within a couple of minutes after shutting it off, it will often not start. I then often have to let it sit for a few minutes before it will start. Also, on hot sunny days it will sometimes not start. The starter will turn fine, but the car won't start.

I have tried a number of things to fix this, but nothing has worked. I've replaced the ICM and the Coil, but that did not do anything for it. Any ideas?

 

alternator

 

WHen the car doesnt start, turn the key into the "ON" position and wait for the check engine light to go out. When it does, you should hear the main relay click at the exact same time the light goes out. If you don't, replace the main relay.

 

How old is the battery?

 

i would have to concur, main relay.

 

the main relay loves to get finicky with heat. It will either be heat from driving it, or heat from sitting in the sun. Replace it and you'll be in the clear. If you're caught with it not starting between now and when you get one, reach under the dash, flick it really hard, and it normally aloows the relay to click back over so it will start properly.
