Proper ignition system evaluation begins by answering three basic diagnostic questions:
1. When you turn the ignition switch to ON (not START), does the Check Engine Light (CEL) come on and then go off after 2 seconds? If not, the problem is with the ACG (ALT) (S) fuse, in the under-dash fuse/relay box; ECM (perform the K-Test, below); Main Relay; or the Ignition Switch. Perform tests in that order.
2. When the CEL goes out, do you hear and/or feel the Main Relay "click"? If not, repair or replace the Main Relay.
3. During the 2 second interval that the CEL is on, do you hear the fuel pump in the gas tank run? If not, check the fuel pump.
Jump main relay connector terminals 5 and 7, turn ignition on, and listen for the fuel pump. If you don't hear it run, then there truly is a problem. Remember, relatively few Honda fuel pumps fail. In fact, I have never seen one, even though many people, at first, suspect they have one.
Be sure and test all under-dash and under-hood fuses with a test light or multimeter. Here's how:

Particularly, focus on the ACG (S) (ALT) fuse.
