Hi everyone! I'm a VW guy but recently bought my first Civic, and I love it.

Yesterday I installed a new head unit, amp, and sub in the civic. Nothing I haven't done a hundred times before. (I did blow a 7.5A fuse, but replaced it and everything seemed to work fine again.)

I went to start the car after I was done and it won't crank. All dash lights come on, HVAC powers up full strength, but I get nothing when I turn the key, not even a click. I used an external 12v trickle charger to make sure it wasn't the battery, and I'm still getting the same problem. I pulled and checked all the fuses under the dash and in the engine compartment, no luck there.

Any ideas?

 

UPDATE: I push started the civic and it started right up. Drove up and down the highway until the IMA battery was 3/4 charged or so, then came home. Tried starting the car immediately after shutting it off, and nothing. Same problem.

The clutch is fully depressed, maybe I jiggled loose a clutch sensor wire in there somewhere?

Is it the original battery? My 2003 civic won't run if the the 12 volt battery is weak. It's on it's 3rd battery.

 

I'm not sure, I've only owned the car for a few months. It was seemingly well taken care of, but I don't have any service history. The battery up until this point has seemed strong. I've push started and driven it twice now, hoping to charge the 12v battery, and I also trickle charged it for 3 hours, and I still don't even get a click when trying to start it.

Weird thing is, when I drive it, the auto-stop works fine, shutting off the engine at stoplights, and then restarting when I shift into gear. So the electric starter seems to work fine...

One more thing: The airbag light comes on and stays on as I drive.

 

there is no electric starter on this car. The hybrid uses the ima system/batteries in the trunk to start the car. If the ima system system can't start the car, the 12volt battery is used to power the backup (normal regular car) starter. you'll be able to hear the difference.
There have been numerous recalls on these hybrid civics for the airbags, software updates and cvt issues.
