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?
