Q: I accidentally put diesel in a gas tank and drove like for 2 blocks.then it stoped.it does start up but does it completely. And si

The fuel system will have to be thoroughly cleaned and that’s about it. A gasoline engine will not run on diesel. Your car was running during those 2 blocks on the gasoline that was in the fuel lines. Once the diesel was drawn into the system by the fuel pump your engine shut down. There is no engine damage but the tank will have to emptied, all lines purged including the fuel rail, the fuel filter changed (if the filter is external) and best practice would be to remove all of the fuel injectors from the fuel rail and send them to a lab, such as Mr. Injector, for cleaning and replacement of the internal filter baskets in the injectors. On car cleaning of injectors is not nearly as good as off car cleaning in a special purpose ultrasonic cleaning machine and on car cleaning will not clean, let alone replace the tiny internal filter in each injector. The filters need to be replaced. The refurbishment of your fuel system can be performed as a mobile service, at your location, if you desire.
