Listen for two clicks when you put the key in the number two position, one when the check engine light comes on and one when the check engine light goes off. If you dont hear it click try tapping on it while putting the car in the number 2 position.

Do you have a factory service manual? Here's how to test your pump using the main relay.



Not 100% sure whether or not it confirms the main relay is bad or not though.

Found this though: http://www.tegger.com/hondafaq/mainr...ing/index.html

Are you getting any type of cranking/starting noise? Does the panel light up? Check the grounds and battery first. Best of luck!
