What causes a 2010 honda civic to shut down immediately after it starts
Could be many things especially with today's modern computerized systems. The best thing to do is get it towed to a dealer or a reputable mechanic to diagnose it properly for you. You could check the fuses and or relays under the dash and under the hood for anything related to the ignition system. See if there are any obvious blown fuses and or loose relays.
Could be the fuel pump also or a clogged fuel filter.
