That is the fuel pump inertia cut-off switch. That is good insight to the fact tht you ran it off the road. It usually takes a good "Ding" to shut them off, but it is worth checking.
The on e for the Sedan is on the hatchback or wagon is in the right rear cargo area above the rear wheel well. On sedans it is on the right side of trunk behind right strut tower. You might have to access it via a cover and it is usually a push button reset. The shortcut I gave you to the diagnostic walk through has a procudure for checking it as it is not just as simple as puching it in to see if it works.
This is from the article just under the picture of the fuel pressure test gauge video;
"To check for this condition locate the inertia switch, if the cut off switch has been active it will have a white or red indicator at the top of the switch. Push this indicator down to disarm the cut off switch, if the indicator does not move down it is not activated and is not the problem.)" From, "How to Chechk a Car that Cranks but Won't Start Problem"
That is proper procedure to check the inetrtia switch which was in the link I gave you.
