Car starts after pumping gas approximately 10 times.
Pumping the gas pedal is only exercising your leg. This car is fuel injected.
I suspect the fuel pump’s anti-backflow valve has failed and maybe the pump is close behind. Try truning the key ON, but not start, back OFF. Repeat this 3-4 times listening for the hum of the fuel pump under the rear seat. Then try and start the car. If it starts right up it it is the anti-backflow valve. Have the fuel pressure checked as well as the fuel pressure regulator.
