2009 Accord 2.4L starts but then turns off by itself with ignition on. Sounds like no fuel, but it will start again and stop running again. Sometimes I can get it to run for a second with gas. No codes. I checked for vacuum leaks, bad connections, battery, etc. Would a worn key cause it to start but not keep running?

 

A worn key wouldn't cause this. A worn key would not turn on the location switch.

Does the car always shut off quickly? Or does it randomly shut off while driving?
