91 civic, 4, lx, sed., 1.5 dpfi

my car runs fine, but every so often, it cuts out gives an engine light and loses maybe a little or maybe almost all power, and cycling the key once makes it run fine again. ecm flashed hello but no code, so there is no code or it didnt store it it sounds like. any ideas?

From your description, it sounds like you could have a bad ignition switch.

Does the dash sometimes go dark when it dies--no warning lights, no electrical?

Do all of the gauges go dark when in the ON position but if held between the on and start position they light up?

Car runs fine when key slightly held at start position?

If it's not the ignition switch, then it's likely the main relay.

Based on what you just said, I would suspect the main relay. Let's see if others agree.

On your Civic, it's probably located in the same position as shown on the CRX diagram:

In this order on Hondas, most major electrical problems are caused by main relays, igniters, coils, and ECMs. If I were you, I would go ahead and replace your igniter, coil, and main relay, just because of the age of your Civic. I would also replace your plugs with new NGKs, if they have more than 20,000 miles on them.
