I have a '94 honda civic dx 1.5l and it has an intermitent no start problem. I changed the coil, rotor, cap, ignition wires and spark plugs. After I did this the car started no problem.next day same thing happened. It would not start. About an hour later without doing anything to the car, it started up again. Is there anything that would cause the car to have this problem. Now at the moment its starts up fine but I think it will happen again and I need to solve this problem before I get stuck somewhere.

I would replace three items, to restore reliability:

. Ignition Control Module (ICM) and coil:

. Main relay--located left of the fuse box, wedged against left kick panel and above the hood latch. Remove fuse box cover and lower dash panel for access.
