Rolled back I turned car off. Now it will not start.

Hi and thanks for using 2CarPros. Com.

If when placed in park, the vehicle still rolled, then there is an issue with the shifter linkage. If the transmission is not actually in park or neutral, it will not start.

You need to check the linkage at the transmission (under the hood) to see if it is moving when you have a helper shift the gears. Also, there is a park/neutral switch that can go bad, however, the idea that it rolled back in park tells me it did not fully shift into park.

Here are directions for repairing the park switch. It shows where the cable attaches to the shift linkage on the transmission and how it comes apart for repair. Make sure the linkage is moving before you take anything apart and let me know what you find.
