My Civic wouldn't start this morning...put key in ignition and turned it to the second position...idiot lights were normal, heard the fuel pump as usual, but also heard terribly loud clicking noises from the left side under the dash. Also heard clicking noises when turning key to start position. Tried all the accessories and they worked...power windows went up and down as normal, stereo played, power door locks worked. Hooked up a battery charger/starter...showed no draw of amps and light indicated full charge. Any ideas? Starter relay? Help!!!

 

its your main relay!!!!
do a search and type in "Main Relay" or something.
The Main relay controls the power to the fuel pump and injectors, it does click if the relay is fried. do you live in hot weather?, that usually does a number on relays!!!! so sweat.

 

There's been a lot of posts like this lately. A lot of them were the main relay.

 

and if it was a begining motor swap it does the same thing if all the grounds are not connected properly on the engine bay.. we did the same thing with a zc sohc vtec into a delsol.. ... just maybe still a noob though.. but check it anyways nothing to loose..

 

If it's the main relay, does it crank but not fire? Mine doesn't even crank. Just the clicking noises.

 

if it is not rotating over then it might be your starter

 

THats ur starter.
