The fuel pump control module is controlled by the ECM - engine control module , Possibility of DTC'S stored ! You need to take to Chevy Dealer !
The engine control module (ECM) supplies voltage to the fuel pump control module (FPCM) when the ECM detects that the ignition is ON. The voltage from the ECM to the FPCM remains active for 2 seconds, unless the engine is in Crank or Run. While this voltage is being received, the FPCM closes the ground switch of the fuel pump and also supplies a varying voltage to the fuel tank pump module in order to maintain the desired fuel rail pressure.

could be a fuse or blown bulb or a short in the switch

The low voltage accessory battery and high voltage hybrid drive battery are in the trunk area. If hit from behind the hybrid battery may have been damaged. The high voltage battery is the one that actually starts the car. This battery is too high voltage for a normal person to check. Call the dealer so they can get in the shop to fix with the right kind safety procedures.
