Q: Engine cranks, but won't turn over

asked by on May 29, 2017

When I turn the ignition key, car engine will crank but not turn over to start. Earlier in the day, car would jerk while accelerating from a complete stop. Also, while decelerating, there is a slight hesitation in the car automatically downshifting. I have replaced the throttle body about 2 months ago. I was thinking it could be the fuel pump?

My car has 143000 miles.
My car has an automatic transmission.
