My Car has been running fine with no problems whatsoever, and one day I came out to start it up and it just wouldn't crank up, and I noticed the check engine light was on. So I just gave up trying to start it, came out the next day and it cranked up. I drove it, parked it, next time I came out to start it, same thing, Check engine light. I replaced the main relay, Tested the fuel pump, and it's fine. After trying to start it , with the ignition on, the check engine light randomly goes off, the relay clicks and the fuel pump starts wizzing, The car will Run fine, and when I turn it off and back on, the check engine light takes only a few seconds to click off, and the fuel pump starts whizzing. But when I try to start it in the morning, the check engine light will not click off. Does this have something to do with the ignition key switch, or the CPU? Any information would be very helpful, Thank's alot!

And one more thing, a couple times the windshield wipers came on when turning the ignition on, and they weren't turned on, I wiggled the key and they stopped.

 

You may have a faulty ignition switch. What year and model Civic do you have?

 

A 92 civic

 

First, use information at this website to retrieve your CEL code:

Second, the picture tells you how to troubleshoot the ignition switch. Note that you may need to wiggle the key as you mentioned to reveal the potential fault.

thanks going to check in the morning .

 

Well, tried to check the CEL number, but the light stays on and doesn't blink, and also the Oil and Temp light are on with the cel.

 

these lights are normal to be on when u turn ur key on and engine isnt runing. sounds like it to me that u have a short some where just take a look under ur dash at wires anything rigged???(not factory) relay could be goin bad or bad ignition switch.

 

This outcome with the CEL indicated that the ECU back up system is in effect (see picture). You may need a new ECU.
