What year is the car, some have 2 fuel pumps, I think the cars with one fuel pump is located under the rear seat drivers side, you can hot wire the pump to see if it's working.
On the reality show Texas cars, they just went thru this in the end it turned out to be a bad throttle body, but they did get the car running, In the end they wound up selling the car for less than they paid for it because they didn't want to spend $1700.00 for a throttle body.
I don't know anything about them I'm just repeating what I saw.
