most likely your egi main relay is bad--it is lh under dash--large grey relay with brown connectorup and towards seat left from brake pedal--it activate fuel pump and are really common to go out--40.00 to 65.00 depending where you get it-p/n 39400-sm4-003 for honda
it is the main relay, i had the same problem
