On the last trip I made my car (Honda Civic 2004 Sedan VP) had trouble starting. It clicked as if it had trouble getting power but eventually started up although the key light was on.

I drove home as it was late at night. Now when I put key in ignition and turn nothing happens at all. No lights, no power, nothing.

A mechanic mentioned when I was getting new tires that my spark plugs were going to need to be changed soon. I have also recently replaced battery a month ago.

I am wondering if bad spark plugs could be the reason for this and would replacing them solve the issue? Also with the keylight turning on previously does this mean that my key needs to be reprogrammed at the dealership. I was able to drive with the light on previously and also have an additional key I have not tried.

  • You might need a new mechanic. Replacing the spark plugs when there is no power sounds fishy. I'd check the ignition key switch.

    That was a comment made at the place that replaced my tires not my regular mechanic. I figured I would have it checked at my upcoming maintenance.

  • Im pretty sure it is linked to the battery connection since it started to be intermittent on your last trip. Check the connection, there is probably some corrosion that you can simply clean and it'll work again. Sep 8, 2015 at 22:31

The spark plugs will certainly not be causing this problem. Check the battery connections.

Some garages will carry out battery checks for free, so this is an easy way of getting the connections checked.

  • You should elaborate on exactly what the OP should be checking WRT the battery connection. Be specific. I agree with what you said, just realize most people when they ask questions like this don't know exactly what your expecting with your answer or they wouldn't have asked the question in the first place.

    @paulster - thanks for the advice. I do think it can be dangerous encouraging people to do something that they don't understand. If they don't know how to check connections on the battery, they would be best asking someone to check them for them.

  • I would also suggest going to a garage. They often do battery checks for free, so they would (hopefully!) tighten the connections. I've edited this in

    @HandyHowie - Just because someone isn't knowledgeable does not mean they aren't capable. Let them decide what they can do. People come to a site like this expecting complete answers. People don't come to this site wanting to see "take it to a mechanic". Sep 7, 2015 at 21:28
  • I'd love to take it to a mechanic as is my intention, but I'd like to avoid having it towed there if possible. I will check battery connections when the rain stops. I'm assuming you mean checking connections for corrosion and tightness.
