2007 Volkswagen Beetle starts & shuts down



car starts for 1/2 second and shuts down, all electric works except dash, fuel ,rpm blinker, etc


Are you quite certain you have enough fuel?

1/3 of a tank, or more?

Do you have another key to try?

It sounds like either a fuel problem, or the pcm may be seeing an unauthorized starting attempt


thanks my other key fixed it
