Dear sir/mam,

I have the car listed above in India. Recently it has been acting problematic. After driving it for a bit it starts jerking and refuses to take acceleration. I understood that the fuel pump was heating up so I put an adjacent electronic fuel pump. But the car still refuses to take the acceleration after being driven a bit. Kindly help please.
