I have replaced the distributor cap, rotor button, plugs, wires, fuel filter and fuel pump. I can crank my car and will run for about half of the day, and wll cut off a few times but will start back up and then all of the sudden will shut it self offand then will not start! HELP! I am ready to throw a cynderblock throug the windshield and say to hell with the mother fu***r

 

Have you looked at the main relay? That's one of the most common ignition related problems with that generation of Civics.

When it won't start, does it just keep cranking but never actually start? When that happens, do you hear a low hum from the back seat area when the key is turned to the point right before it would start?
