I have a 2007 Honda Civic with 1.8 liter in it. Used the car night before was a little sluggish but seem to clear out .go out to go to work next morning started and shut right off. Did some testing later that day and would run off carb cleaner so thought was fuel pump. Replaced pump and still does same thing. Any suggestions?

Might be flooded? Try starting with the gas pedal fully depressed. This shuts off injectors and allows maximum amount of air into the cylinders.

For future reference test as much as possible before replacing parts. A fuel pressure test would have revealed if the fuel pump is working correctly or not.
